DETAILED DESCRIPTION



[0013] In order to make the objects, the technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in a clear and complete manner in conjunction with the drawings and embodiments. Obviously, the following embodiments merely relate to a part of, rather than all of, the embodiments of the present disclosure, and based on these embodiments, a person skilled in the art may, without any creative effort, obtain the other embodiments, which also fall within the scope of the present disclosure.

[0014] Fig.1 shows a radio resource configuration system. As shown in Fig.1, the system includes a UE 11 and a base station 12. The UE 11 may be, e.g., a mobile phone, a tablet personal computer, a laptop computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID) or a wearable device. It should be appreciated that, the type of the UE will not be particularly defined herein. The base station 12 may be a 5G base station (e.g., gNB, 5G New Radio (NR) Node B (NB)). It should be appreciated that, the type of the base station will not be particularly defined herein.

[0015] It should be appreciated that, functions of the UE 11 and the base station 12 will be described hereinafter in conjunction with the embodiments.

[0016] In addition, in the embodiments of the present disclosure, the UE 11 and the base station 12 may each support Dual Connectivity (DC) architecture including two cell groups, i.e., an MCG and an SCG, and support a DPCP duplication function, so as to generate the following different bearer types.

[0017] MCG bearer: a PDCP entity, an RLC entity and an MAC entity corresponding to the MCG bearer, as shown in Fig.2.

[0018] SCG bearer: a PDCP entity, an RLC entity and an MAC entity corresponding to the SCG bearer, as shown in Fig.2.

[0019] Split bearer: a PDCP entity corresponding to the split bearer is located in one cell group, and two RLC entities and two MAC entities corresponding to the split bearer are located in different cell groups, as shown in Fig.3.

[0020] Duplicate bearer: one PDCP entity, two RLC entities and one MAC entity corresponding to the duplicate bearer are located in one cell group, as shown in Fig.4.

[0021] In Figs.2 and 4, the architecture for the UE is taken as an example.

[0022] The present disclosure provides in some embodiments a radio resource configuration method applied for a base station which, as shown in Fig. 5, includes the following steps.

[0023] Step 501: acquiring an arrival time of each data packet, the arrival time including a time when the data packet arrives at an SDAP layer, a time when the data packet arrives at a PDCP layer, a time when the data packet arrives at the PDCP layer and is placed into a reordering window, a time when the data packet arrives at an RLC layer, or a time when the data packet arrives at an MAC layer.

[0024] Each data packet may be a downlink data packet or an uplink data packet. In addition, during the calculation of an average delay of the downlink data packets, the arrival time may include the time when the data packet arrives at the SDAP layer, the time when the data packet arrives at the PDCP layer, the time when the data packet arrives at the RLC layer, or the time when the data packet arrives at the MAC layer. During the calculation of a proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than a predetermined delay threshold, the arrival time may include the time when the data packet arrives at the PDCP layer or the time when the data packet arrives at the PDCP layer and is placed into the reordering window.

[0025] Step 502: acquiring a delivery time or a reception time of each data packet, the delivery time being a time when the data packet is transmitted from the PDCP layer to a high-layer protocol entity, and the reception time being a time when the data packet has been received successfully.

[0026] During the calculation of the average delay of the downlink data packets, Step 502 may include acquiring the reception time of each data packet, and during the calculation of the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold, Step 502 may include acquiring the delivery time of each data packet. The time when the data packet has been received successfully may be understood as a time when a feedback has been received successfully from a UE.

[0027] In addition, the high-layer protocol entity may be a protocol entity in a protocol stack higher than the PDCP layer.

[0028] Step 503: calculating an average delay of the downlink data packets within a certain time period or a proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period based on the arrival time and the delivery time or the reception time, the average delay of the downlink data packets including within a certain time period, one or more of the average delay of the downlink data packets by a same UE, in a same bearer type, in a same transmission path, on a same RB, and in a same QoS flow.

[0029] Step 503 may be understood as calculating the average delay of the downlink data packets within a certain time period based on the arrival time and the reception time, or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period based on the arrival time and the delivery time.

[0030] In addition, in the embodiments of the present disclosure, the average delay of the downlink data packets may be understood as an average delivery delay of the downlink data packets. The average delivery delay may be an average value of differences between the arrival time and the reception time (i.e., the time when the feedback has been received from the UE successfully) of each downlink data packet within a certain time period.

[0031] It should be appreciated that, the data packet in Steps 501 and 502 may be any data packet within the time period. In the embodiments of the present disclosure, each data packet within the time period may refer to that mentioned in Steps 501 and 502, and thus will not be particularly defined herein. To be specific, a delivery delay of each uplink data packet within the time period may be calculated so as to calculate the average delay of the downlink data packets within a certain time period, or the reordering delay of each downlink data packet at the PDCP layer within the time period may be calculated so as to calculate the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period.

[0032] In addition, the average delay of the downlink data packets received by the same UE within a certain time period may be an average delivery delay of the downlink data packets for the same UE within the time period. The average delay of the downlink data packets of the same bearer type within a certain time period may be an average delivery delay of the downlink data packets of a certain bearer type (e.g., the MCG bearer, the SCG bearer, the split bearer or the duplicate bearer). The average delay of the downlink data packets transmitted on the same RB within a certain time period may be an average delivery delay of the downlink data packets received on a certain RB within the time period. The average delay of the downlink data packets for a same QoS flow within a certain time period may be an average delivery delay of the downlink data packets for a certain QoS flow within the time period.

[0033] It should be appreciated that, in the embodiments of the present disclosure, an average delivery delay of the downlink data packets with a same QoS Class Identifier (QCI) may also be calculated.

[0034] Step 504: performing radio resource configuration based on the calculated average delay or proportion.

[0035] When the delivery delay of the downlink data packet for one UE is greater than the predetermined delay threshold, the base station may quickly schedule the downlink data transmission for the UE, so as to reduce the delivery delay of the data packets for the UE. For another example, when the delivery delay of the downlink data packet for one UE is smaller than the predetermined delay threshold and the downlink data packets are being transmitted to the UE, the base station may preferentially schedule the downlink data transmission for the other UEs, so as to reduce the downlink delivery delay for the other UEs while appropriately increasing the downlink delivery delay of the UE, thereby to reduce the delivery delay of the data packets in the entire network.

[0036] When the reordering delay of the uplink data packets from one UE at the PDCP layer is greater than the predetermined delay threshold, the base station may set a smaller value for a reordering timer, so as to reduce the reordering delay of the uplink data packets from the UE at the PDCP layer. For another example, when the reordering delay of the uplink data packets from one UE at the PDCP layer is smaller than the predetermined delay threshold, the base station may set a larger value for the reordering timer, so as to reduce the quantity of the uplink data packets discarded due to the expiration of the reordering timer while appropriately increasing the delivery delay of the uplink data from the UE.

[0037] It should be appreciated that, the above examples are merely for illustrative purposes, and in the embodiments of the present disclosure, the radio resource configuration will not be particularly defined. Through the above steps, it is able to reduce the delivery delay at the UE.

[0038] In the embodiments of the present disclosure, the arrival time of each data packet may be acquired, and the arrival time may include the time when the data packet arrives at the SDAP layer, the time when the data packet arrives at the PDCP layer, the time when the data packet arrives at the PDCP layer and is placed into the reordering window, the time when the data packet arrives at the RLC layer, or the time when the data packet arrives at the MAC layer. Next, the delivery time or the reception time of each data packet may be acquired, the delivery time may be the time when the data packet is transmitted from the PDCP layer to the high-layer protocol entity, and the reception time may be the time when the data packet has been received successfully. Next, the average delay of the downlink data packets within a certain time period or the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period may be calculated based on the arrival time and the delivery time or the reception time, and the average delay of the downlink data packet may include within a certain time period, one or more of the average delay of the downlink data packets by the same UE, in a same bearer type, in a same transmission path, on a same RB and in a same Qos flow. Then, the radio resource configuration may be performed based on the calculated average delay or proportion. As a result, it is able to acquire, through calculation, the delay adapted to the functions introduced into the 5G communication system, and perform the radio resource configuration based on the calculated delay, thereby to improve the performance of the communication system and further reduce the delivery delay of the data packets in the network.

[0039] As shown in Fig.6, the radio resource configuration method may include the following steps.

[0040] Step 601: acquiring the arrival time of each data packet, the arrival time including the time when the data packet arrives at the SDAP layer, the time when the data packet arrives at the PDCP layer, the time the data packet arrives at the RLC layer, or the time when the data packet arrives at the MAC layer.

[0041] In the embodiments of the present disclosure, the data packet may be a downlink data packet. In Step 601, the time when each downlink data packet arrives at the SDAP layer, the time when each downlink data packet arrives at the PDCP layer, the time when each downlink data packet arrives at the RLC layer or the time when each downlink data packet arrives at the MAC layer may be acquired during the transmission of the downlink data packet.

[0042] Different arrival times may be acquired depending on different bearer types and different protocol entities of the base station. For example, when the base station includes an SDAP entity, the time when the downlink data packet arrives at the SDAP layer may be acquired; or when the base station does not include the SDAP entity, the arrival time when the downlink data packet arrives at the PDCP layer may be acquired; or when the split bearer is provided but the base station does not include PDCP entity, the time when the downlink data packet arrives at the RLC layer may be acquired; or when the downlink data packet is a Media Access Control Service Data Unit (MAC SDU) or a Media Access Control Packet Data unit (MAC PDU), the time when the downlink data packet arrives at the MAC layer may be acquired.

[0043] Due to different bearer types and different protocol entities of the base station, in Step 601, it is able to acquire different arrival times based on the bearer types, thereby to calculate the delay in a more flexible manner and meet the requirement of the 5G communication system in a better manner.

[0044] Step 602: acquiring the reception time of each data packet, the reception time being the time when the data packet has been received successfully.

[0045] The time when the data packet has been received successfully may include a time when an RLC feedback of the data packet has been received successfully or a time when a PDCP feedback of the data packet has been received successfully.

[0046] The time when the RLC feedback of the data packet has been received successfully may be a reception time when the base station has received a feedback indicating that the data packet has been successfully received from the UE at the RLC layer, and the time when the PDCP feedback of the data packet has been received successfully may be a reception time when the base station has received a feedback indicating that the data packet has been successfully received from the UE at the PDCP layer. Of course, in the embodiments of the present disclosure, the reception time may also be a time when a Hybrid Automatic Repeat reQuest (HRA) feedback has been received successfully, which will not be particularly defined herein.

[0047] Step 603: calculating the average delay of the downlink data packets within a certain time period based on the arrival time and the reception time, the average delay of the downlink data packets including, within a certain time period, one or more of the average delay of the downlink data packets by the same UE, in a same bearer type, in a same transmission path, on a same RB and in a same Qos flow.

[0048] During the calculation of the average delay of the downlink data packets, the delivery delay of each downlink data packet for which the feedback has been received successfully may be calculated in Steps 601 and 602, and then the average delivery delay of all the downlink data packets for which the feedbacks have been received successfully may be calculated, e.g., through the following equation:

where meanings of the items in the equation are shown in Table 1.
Table 1
M(T, qci) average delay of the data packets
tArriv(i) arrival time of data packet i
tAck(i) reception time of data packet i
i data packet i
I(T) the total quantity of the data packets within a time period for a measurement item
T the time period for the measurement item


[0049] During the calculation of the average delivery delay of the downlink data packets, the data packet for which no indication information indicating that the data packet has been received successfully (i.e., no feedback has been received successfully) shall not be taken into consideration. For example, in the above equation, the data packet i is a downlink data packet for which the feedback has been received successfully. In addition, all the data packets mentioned hereinabove may merely include the downlink data packets for which the feedbacks have been received successfully.

[0050] In addition, in a situation where a duplicate data packet has been transmitted (e.g., the data packet i has been retransmitted twice), the data packet i with the shortest delivery delay may be taken into consideration. In this way, it is able to prevent the delivery delay of the same data packet from being calculated several times, thereby to improve the calculation accuracy. In addition, when the shortest delivery delay is used, it is able to calculate the average delivery delay in a more effective manner.

[0051] In a possible embodiment of the present disclosure, the downlink data packets may include one or more of a Service Data Adaptation Protocol Service Data Unit (SDAP SDU), a Service Data Adaptation Protocol Packet Data Unit (SDAP PDU), a Packet Data Convergence Protocol Service Data Unit (PDCP SDU), a Packet Data Convergence Protocol Packet Data Unit (PDCP PDU), a Radio Link Control Service Data Unit (RLC SDU), a Radio Link Control Packet Data Unit (RLC PDU), an MAC SDU and an MAC PDU.

[0052] When the base station includes the SDAP entity, the downlink data packets may include the SDAP SDU and/or the SDAP PDU. When the base station does not include any SDAP entity, the downlink data packets may include the PDCP SDU and/or the PDCP PDU. When the split bearer is adopted and the base station does not include any PDCP entity, the downlink data packets may include the RLC SDU and/or the RLC PDU. In some other scenarios, the downlink data packets may include the MAC SDU and/or the MAC PDU.

[0053] In the embodiments of the present disclosure, it is able to calculate the delays of different downlink data packets based on bear type for the base station, so as to meet the requirement of the 5G communication system, thereby to improve the performance of the 5G communication system.

[0054] Step 604: performing radio resource configuration based on the calculated average delay.

[0055] When the delivery delay of the downlink data packet for one UE is greater than the predetermined delay threshold, the base station may quickly schedule the downlink data transmission for the UE, so as to reduce the delivery delay of the data packets for the UE. For another example, when the delivery delay of the downlink data packet for one UE is smaller than the predetermined delay threshold and the downlink data packets are being transmitted to the UE, the base station may preferentially schedule the downlink data transmission for the other UEs, so as to reduce the downlink delivery delay for the other UEs while appropriately increasing the downlink delivery delay for the UE , thereby to reduce the delivery delay of the data packets in the entire network.

[0056] It should be appreciated that, the above examples are merely for illustrative purposes, and in the embodiments of the present disclosure, the radio resource configuration will not be particularly defined. Through the above steps, it is able to improve the performance of the communication system, and further reduce the delivery delay of the data packets in the network.

[0057] As shown in Fig.7, the radio resource configuration method may include the following steps.

[0058] Step 701: acquiring the arrival time of each data packet, the arrival time including the time when the data packet arrives at the PDCP layer, or the time when the data packet arrives at the PDCP layer and is placed into the reordering window.

[0059] In the embodiments of the present disclosure, the data packet may be an uplink data packet. The reordering window may be a reordering window arranged at the PDCP layer and configured to reorder the disordered data packets. In Step 701, the time when the data packet arrives at the PDCP layer or the time when the data packet arrives at the PDCP layer and is placed into the reordering window may be acquired, so as to calculate a time when the uplink data packets are reordered at the PDCP layer.

[0060] Step 702: acquiring the delivery time of each data packet, the delivery time being a time when the data packet is transmitted from the PDCP layer to the high-layer protocol entity.

[0061] Step 703: calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period based on the arrival time and the delivery time.

[0062] In Step 703, the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold within a certain time period may be selectively calculated according to the requirements of the network, the services or the UE, so as to perform the radio resource configuration flexibly. In addition, it should be appreciated that, when calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold, different predetermined delay thresholds may be adopted. In other words, two predetermined delay thresholds may be provided, a larger one may be used for the calculation of the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than the predetermined delay threshold, and a smaller one may be used for the calculation of the proportion of the uplink data packets whose reordering delay at the PDCP layer is smaller than the predetermined delay threshold. In this way, it is able to calculate the delay in a more accurate manner. Of course, in some scenarios, a same predetermined delay threshold may be adopted, which will not be particularly defined herein.

[0063] In the embodiments of the present disclosure, during the calculation of the proportion, the reordering delay of each uplink data packet at the PDCP layer may be calculated in Steps 701 and 702, and this reordering delay may be equal to a value acquired by subtracting the arrival time from the delivery time of the uplink data packet. For example, the proportion may be calculated through the following equations:

where meanings of the items in the tULdelay(i, qci) = tDeliv(i, qci) - tArrival(i, qci) equations are shown in Table 2.
Table 2
M(T, qci) the proportion of the data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold
nExcess(T, qci) the quantity of the data packets whose reordering delay within a time period T is greater than or smaller than a predetermined delay threshold tULdelay(i, qci)
nTotal(T, qci) the quantity of the data packets transmitted within the time period T
tULdelay(i, qci) the delay of the data packet i from the arrival time to the delivery time
tDeliv(i, qci) the delivery time of the data packet i
tArrival(i, qci) the arrival time of the data packet i
i the data packet i within the time period T
T the time period for the measurement


[0064] In a possible embodiment of the present disclosure, the uplink data packets for the calculation of the proportion may include all the uplink data packets received within the time period, the uplink data packets from the same UE, the uplink data packets with the same QCI, the uplink data packets on the same bearer, the uplink data packets in the same QoS flow, the uplink data packets transmitted on the same RB and through the same path, the uplink data packets in the same cell group, or the uplink data packets of the same bearer type.

[0065] Based on the above uplink data packets, it may be calculated that the proportion of the above uplink data packets to: all the uplink data packets received within the time period; or the uplink data packets received from the same UE within the time period; or uplink data packets with the same QCI received within the time period; or the uplink data packets received on the same bearer within the time period; or the uplink data packets for the same QoS flow received within the time period; or the uplink data packets received on the same RB and through the same path within the same time period; or the uplink data packets for the same cell group received within the time period; or the uplink data packets of the same bearer type received within the time period.

[0066] Step 703 may include: calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to all the uplink data packets received by the base station within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station from the same UE within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets with the same QCI received by the base station within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station on the same bearer within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets in the same QoS flow received by the base station within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station on the same RB and through the same path within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets in the same cell group received by the base station within the time period; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets of the same bearer type received by the base station within the time period.

[0067] The calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station on the same RB and in the same path within the time period may include: calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station on a certain split bearer and through a certain path within the base station; or calculating the proportion of the uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold to the uplink data packets received by the base station on a certain duplicate bearer and in a certain path within the time period.

[0068] In this regard, it is able to calculate the proportion in a more accurate manner, thereby to meet the requirements on the new functions introduced into the 5G communication system, and improve the performance of the communication system.

[0069] In a possible embodiment of the present disclosure, the uplink data packet may include one or more of a PDCP SDU, a PDCP PDU and an RLC SDU.

[0070] In the embodiments of the present disclosure, it is able to calculate the proportion of different uplink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold, thereby to improve the system flexibility.

[0071] In another possible embodiment of the present disclosure, the uplink data packets for the calculation of the proportion may include: one uplink data packet among the uplink data packets which have been received repeatedly within the time period; or the uplink data packets received within the time period and located in the reordering window, and the uplink data packets located within the reordering window but ignored due to the expiration of the reordering timer at the PDCP layer. A reordering delay of the ignored uplink data packet may be a time value of the reordering timer, and the reordering window may be a data packet sequence window.

[0072] In the embodiments of the present disclosure, for the uplink data packet which has been received repeatedly, merely one reordering delay of the uplink data packet at the PDCP layer may be calculated. To be specific, a first-time reordering delay of the uplink data packet at the PDCP layer may be calculated, i.e., the uplink data packet received at the other times may not be taken as the data packet for the calculation of the proportion, so as to ensure the correct proportion.

[0073] In addition, during the calculation of the proportion, merely the delay of the data packets received within the time period and in the reordering window may be calculated, and the discarded data packet i outside the reordering window may not be taken into consideration. In other words, the calculated proportion is merely the proportion of the data packets in the reordering window, so as to accurately reflect the performance of the PDCP layer.

[0074] In addition, during the calculation of the proportion, the delay of the data packet ignored due to the expiration of the reordering timer may be the time value of the reordering timer, so as to prevent the occurrence of such a situation where it is impossible to calculate the proportion when some data packets are ignored due to the expiration of the reordering timer. Furthermore, the value (the time value) of the reordering timer may be taken as the delay of the ignored data packet, so as to ensure an effect of the reordering timer. This is because, when the data packet is ignored by the reordering timer, it means that the delay of the data packet exceeds the time value of the reordering timer.

[0075] For example, data packets 1 to 10 may be located in the reordering window. When the data packet 10 has currently been received but the data packet 8 has not been received, the reordering timer may be started during the reception of the data packet 10. When the data packet 8 has not been received yet before the expiration of the reordering timer, the value of the reordering timer may be taken as the reordering delay of the data packet 8. When the data packet 8 has been received before the expiration of the reordering timer, it may belong to the data packets received within the time period and located in the reordering window.

[0076] Step 704: performing radio resource configuration based on the calculated proportion.

[0077] For example, when the reordering delay of the uplink data packets from one UE at the PDCP layer is greater than the predetermined delay threshold, the base station may set a smaller value for the reordering timer, so as to reduce the reordering delay of the uplink data packets from the UE at the PDCP layer. For another example, when the reordering delay of the uplink data packets from one UE at the PDCP layer is smaller than the predetermined delay threshold, the base station may set a larger value for the reordering timer, so as to reduce the quantity of the uplink data packets discarded due to the expiration of the reordering timer while appropriately increasing the delivery delay of the uplink data from the UE.

[0078] It should be appreciated that, the above examples are merely for illustrative purposes, and in the embodiments of the present disclosure, the radio resource configuration will not be particularly defined. Through the above steps, it is able to improve the performance of the communication system, and further reduce the delivery delay of the data packets in the network.

[0079] The present disclosure further provides in some embodiments a radio resource configuration method applied for a UE which, as shown in Fig. 8, includes the following steps.

[0080] Step 801: acquiring an arrival time of each data packet, the arrival time including a time when the data packet arrives at an SDAP layer, a time when the data packet arrives at a PDCP layer, a time when the data packet arrives at the PDCP layer and is placed into a reordering window, a time when the data packet arrives at an RLC layer, or a time when the data packet arrives at an MAC layer.

[0081] During the calculation of a proportion of uplink data packets each with a delivery delay, the arrival time may include the time when the data packet arrives at the SDAP layer, the time when the data packet arrives at the PDCP layer, the time when the data packet arrives at the RLC layer, or the time when the data packet arrives at the MAC layer. During the calculation of a proportion of the downlink data packets whose reordering delay at the PDCP layer is greater than or smaller than a predetermined delay threshold, the arrival time may include the time when the data packet arrives at the PDCP layer or the time when the data packet arrives at the PDCP layer and is placed into the reordering window.

[0082] The arrival time of each uplink data packet acquired by the UE may refer to the arrival time of each downlink data packet acquired by the base station as shown in Figs. 5-6, and the arrival time of each downlink data packet acquired by the UE may refer to the arrival time of each uplink data packet acquired by the base station as shown in Figs.5 and 7, which will not be particularly defined herein.

[0083] Step 802: acquiring a delivery time of each data packet, the delivery time being a time when the data packet is transmitted from the PDCP layer to a high-layer protocol entity, a time when the data packet is transmitted to a physical layer PHY, a time when the data packet is transmitted through an air interface, or a time when a feedback of the data packet has been received successfully.

[0084] During the calculation of the proportion of the uplink data packets each with the delivery delay, the delivery time may include the time when the data packet is transmitted to the physical layer PHY, the time when the data packet is transmitted via the air interface, or the time when the feedback of the data packet has been received successfully. During the calculation of the proportion of the downlink data packets each with the reordering delay at the PDCP layer, the delivery time may include the time when the data packet is transmitted from the PDCP layer to the high-layer protocol entity.

[0085] The time when the feedback of the data packet has been received successfully may include a time when an HARQ feedback has been received successfully, a time when an RLC feedback of the data packet has been received successfully or a time when a PDCP feedback of the data packet has been received successfully.

[0086] Step 803: calculating the proportion of the data packets whose delay is greater than or smaller than a predetermined delay threshold within a certain time period based on the arrival time and the delivery time, the delay of the data packets including the reordering delay of the downlink data packets at the PDCP layer or the delivery delay of the uplink data packets, the proportion including one or more of a proportion in data packets for the UE, a proportion in data packets on a same RB, a proportion in data packets in a same QoS flow, a proportion in data packets received on a same split bearer and in a same path, a proportion in data packets received on a same duplicate bearer and in a same path, a proportion in data packets in a same cell group, and a proportion in data packets of a same bearer type.

[0087] Step 803 may be understood as calculating the proportion of the downlink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold or calculating the proportion of the uplink data packets whose delivery delay is greater than or smaller than the predetermined delay threshold based on the arrival time and the delivery time. Different predetermined delay thresholds may be adopted, so as to improve the calculation accuracy. Of course, in some scenarios, a same predetermined delay threshold may also be adopted.

[0088] The meaning of the calculation of the proportion in the data packets received by the UE, the proportion in the data packets on the same RB, the proportion in the data packets in the same QoS flow, the proportion in the data packets received on the same split bearer and in the same path, the proportion in the data packets received on a same duplicate bearer and in a same path, the proportion in the data packets in the same cell group or the proportion in the data packets of a same bearer type may be that, the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets for the UE may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets on a certain RB may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets for a certain QoS flow may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets on a certain split bearer and through a certain path may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets on a certain duplicate bearer and through a certain path may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets for a certain cell group may be calculated; the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold to the data packets of a certain bearer type may be calculated.

[0089] Step 804: transmitting the calculated proportion to the base station, so that the base station performs the radio resource configuration based on the proportion.

[0090] After the calculation of the proportion, the UE may report the calculated proportion to the base station, so that the base station performs the radio resource configuration based on the proportion.

[0091] When the delivery delay of the uplink data packet for one UE is greater than the predetermined delay threshold, the base station may quickly schedule the uplink data transmission for the UE, so as to reduce the delivery delay of the data packets for the UE. For another example, when the delivery delay of the uplink data packet for one UE is smaller than the predetermined delay threshold and the uplink data packets are being transmitted, the base station may preferentially schedule the uplink data transmission for the other UEs, so as to reduce the uplink delivery delay for the other UEs while appropriately increasing the delivery delay of the uplink data for the UE, thereby to reduce the delivery delay of the data packets in the entire network.

[0092] When the reordering delay of the downlink data packets for one UE at the PDCP layer is greater than the predetermined delay threshold, the base station may set a smaller value for a reordering timer, so as to reduce the reordering delay of the downlink data packets for the UE at the PDCP layer. For another example, when the reordering delay of the downlink data packets for one UE at the PDCP layer is smaller than the predetermined delay threshold, the base station may set a larger value for the reordering timer, so as to reduce the quantity of the downlink data packets discarded due to the expiration of the reordering timer while appropriately increasing the delivery delay of the uplink data from the UE.

[0093] It should be appreciated that, the above examples are merely for illustrative purposes, and in the embodiments of the present disclosure, the radio resource configuration will not be particularly defined. Through the above steps, it is able to reduce the delivery delay at the UE.

[0094] According to the embodiments of the present disclosure, through the above steps, it is able to acquire, through calculation, the delay adapted to the functions introduced into the 5G communication system, and perform the radio resource configuration based on the calculated delay, thereby to improve the performance of the communication system and further reduce the delivery delay of the data packets in the network.

[0095] As shown in Fig.9, the radio resource configuration method for the UE may include the following steps.

[0096] Step 901: receiving configuration information for calculating the delay of each data packet from the base station. The configuration information may include one or more of a measurement item identifier, a to-be-measured object identifier, and a report trigger configuration.

[0097] The measurement item identifier may include a measurement item identifier for the delivery delay of each uplink data packet or a measurement item identifier for the reordering delay of each downlink data packet at the PDCP layer.

[0098] The measurement item identifier for the delivery delay of each uplink data packet may be used to indicate the UE to calculate the delivery delay of the uplink data packet, and the measurement item identifier for the reordering delay of each downlink data packet at the PDCP layer may be used to indicate the UE to calculate the reordering delay of the downlink data packet at the PDCP layer.

[0099] The to-be-measured object identifier may be used to indicate the UE to measure a specific object, and it may include one or more a QoS flow identifier, a split bearer path identifier, a duplicate bearer path identifier, a bearer type identifier and a cell group identifier.

[0100] The cell group identifier may be MCG or SCG, and the bearer type identifier may include at least one of an MCG bearer, an SCG bearer, a split bearer and a duplicate bearer.

[0101] Through the to-be-measured object identifier, it is able to indicate the UE to calculate the delay of the specific object, thereby to improve the system flexibility. In addition, it is able to prevent the UE from measuring all the objects, thereby to reduce the power consumption of the UE.

[0102] The report trigger configuration may be a trigger condition for triggering the UE to report a calculation result. For example, the report trigger configuration may include a predetermined delay threshold, a predetermined proportion threshold, a predetermined reporting condition, and a period of a periodical reporting operation.

[0103] The predetermined reporting condition may include one or more of a first predetermined condition, a second predetermined condition, a third predetermined condition and a fourth predetermined condition.

[0104] To be specific, upon the receipt of the report trigger configuration, the UE may parse the above contents so as to acquire one or more of: a configuration indicating that the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is greater than the predetermined delay threshold meets the first predetermined condition; a configuration indicating that the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is smaller than the predetermined delay threshold meets the second predetermined condition; a configuration indicating that the proportion of the data packets whose delivery delay within a certain time period is smaller than the predetermined delay threshold meets the third predetermined condition; a configuration indicating that the proportion of the data packets whose delivery delay within a certain time period is greater than the predetermined delay threshold meets the fourth predetermined condition; and a configuration indicating the periodical reporting operation.

[0105] The first predetermined condition may be a condition where the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is greater than the predetermined delay threshold is greater than or smaller than the predetermined proportion threshold.

[0106] The second predetermined condition may be a condition where the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is smaller than the predetermined delay threshold is greater than or smaller than the predetermined proportion threshold.

[0107] The third predetermined condition may be a condition where the proportion of the uplink data packets whose delivery delay within a certain time period is greater than the predetermined delay threshold is smaller than the predetermined proportion threshold.

[0108] The fourth predetermined condition may be a condition where the proportion of the uplink data packets whose delivery delay within a certain time period is smaller than the predetermined delay threshold is greater than or smaller than the predetermined proportion threshold.

[0109] In addition, for the periodical reporting operation, the UE may directly report the calculation result periodically, i.e., at a predetermined interval, or may periodically report the calculation result when the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is greater than the predetermined delay threshold is greater than the predetermined proportion threshold, or may periodically report the calculation result when the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is greater than the predetermined delay threshold is smaller than the predetermined proportion threshold, or may periodically report the calculation result when the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is smaller than the predetermined delay threshold is greater than the predetermined proportion threshold, or may periodically report the calculation result when the proportion of the data packets whose reordering delay at the PDCP layer within a certain time period is smaller than the predetermined delay threshold is smaller than the predetermined proportion threshold, or may periodically report the calculation result when the proportion of the uplink data packets whose delivery delay within a certain time period is greater than the predetermined delay threshold is greater than the predetermined proportion threshold; or may periodically report the calculation result when the proportion of the uplink data packets whose delivery delay within a certain time period is greater than the predetermined delay threshold is smaller than the predetermined proportion threshold; or may periodically report the calculation result when the proportion of the uplink data packets whose delivery delay within a certain time period is smaller than the predetermined delay threshold is greater than the predetermined proportion threshold; or may periodically report the calculation result when the proportion of the uplink data packets whose delivery delay within a certain time period is smaller than the predetermined delay threshold is smaller than the predetermined proportion threshold.

[0110] Through the report trigger configuration, it is able to indicate the UE to report the calculation result flexibly, thereby to save the functions and the transmission resources of the UE.

[0111] In a possible embodiment of the present disclosure, the configuration information may further include one or more of time window information about the time period, a predetermined delay threshold in the report trigger configuration, predetermined conditions in the report trigger configuration, and a period of the periodical reporting operation.

[0112] The predetermined delay threshold in the report trigger configuration may include the delay threshold corresponding to the reordering delay of the data packets at the PDCP layer and/or the delay threshold corresponding to the delivery delay. The predetermined conditions in the report trigger configuration may include one or more of the first predetermined condition, the second predetermined condition, the third predetermined condition and the fourth predetermined condition.

[0113] Of course, the above information may be defined in a protocol or pre-configured by the UE. For example, the time window information about the time period may be 10ms, the predetermined delay threshold may be 10ms, the predetermined proportion threshold may be 10%, and the period of the periodical reporting operation may be 50ms.

[0114] In this regard, it is able to flexibly configure relevant parameters for the UE, so as to improve a radio resource configuration effect.

[0115] It should be appreciated that, in the embodiments of the present disclosure, Step 901 may be optional. For example, the configuration information may be pre-configured by the UE or defined in a protocol. In addition, in Figs.5 to 7, the radio resource configuration method may further include a step of transmitting, by the base station, the configuration information to the UE with a same beneficial effect, which will not be particularly defined herein.

[0116] Step 902: acquiring the arrival time of each data packet, the arrival time including the time when the data packet arrives at the SDAP layer, the time when the data packet arrives at the PDCP layer, the time when the data packet arrives at the PDCP layer and is placed into the reordering window, the time when the data packet arrives at the RLC layer or the time when the data packet arrives at the MAC layer.

[0117] Step 903: acquiring the delivery time of the each data packet, the delivery time being the time when the data packet is transmitted from the PDCP layer to the high-layer protocol entity, the time when the data packet is transmitted to the physical layer PHY, the time when the data packet is transmitted through the air interface, or the time when the feedback of the data packet has been received. The feedback may be used to represent that the base station has received the data packet successfully.

[0118] Step 904: calculating the proportion of the data packets whose delay is greater than or smaller than the predetermined delay threshold within a certain time period based on the arrival time and the delivery time, the delay of the data packet including the reordering delay of the downlink data packet at the PDCP layer or the delivery delay of the uplink data packet, the proportion including one or more of the proportion in the data packets for the UE, the proportion in the data packets on a same RB, the proportion in the data packets in a same QoS flow, the proportion in the data packets received on a same split bearer and in a same path, the proportion in the data packets received on a same duplicate bearer and in a same path, the proportion in the data packets in a same cell group, and the proportion in the data packets of a same bearer type.

[0119] In Step 904, the proportion may be calculated based on the configuration information, and in Steps 902 and 903, the arrival time and the delivery time of the data packet may be acquired based on the configuration information.

[0120] During the calculation of the proportion of the uplink data packets whose delivery delay is greater than or smaller than the predetermined delay threshold, the delivery delay of each uplink data packet may be calculated in Steps 902 and 903, and then the proportion may be calculated through the following equations:

where meanings of the items in the tULdelay(i, qci) = tDeliv(i, qci) - tArrival(i, qci) equations are shown in Table 3.
Table 3
M(T, qci) the proportion of the data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold
nExcess(T, qci) the quantity of the data packets whose delay within a time period T is greater than or smaller than the predetermined delay threshold tULdelay(i, qci)
nTotal(T, qci) the quantity of the data packets transmitted within the time period T
tULdelay(i, qci) the delay of the data packet i from the arrival time to the delivery time
tDeliv(i, qci) the delivery time of the data packet i
tArrival(i, qci) the arrival time of the data packet i
i the data packet i within the time period T
T the time period for the measurement


[0121] During the calculation of the proportion of the downlink data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold, the reordering delay of each downlink data packet at the PCDP layer may be calculated in Steps 902 and 903, and then the proportion may be calculated through the following equations:

where meanings of the items in the tULdelay(i, qci) = tDeliv(i, qci) - tArrival(i, qci) equations are shown in Table 4.
Table 4
M(T, qci) the proportion of the data packets whose reordering delay at the PDCP layer is greater than or smaller than the predetermined delay threshold
nExcess(T, qci) the quantity of the data packets whose delay within a time period T is greater than or smaller than a predetermined delay threshold tULdelay(i, qci)
nTotal(T, qci) the quantity of the data packets transmitted within the time period T
tULdelay(i, qci) the delay of the data packet i from the arrival time to the delivery time
tDeliv(i, qci) the delivery time of the data packet i
tArrival(i, qci) the arrival time of the data packet i
i the data packet i within the time period T
T the time period for the measurement


[0122] It should be appreciated that, in the embodiments of the present disclosure, the calculation of the proportion may not be limited to the above equations, which will not be particularly defined herein.

[0123] In a possible embodiment of the present disclosure, when the delay of each data packet includes the delivery delay of the uplink data packet, the data packet may include one of more of an SDAP SDU, SDAP PDU, a PDCP SDU, a PDCP PDU, an RLC SDU, an RLC PDU, an MAC SDU and an MAC PDU.

[0124] When the delay of each data packet includes the reordering delay of the downlink data packet at the PDCP layer, the data packet may include one or more of a PDCP SDU, a PDCP PDU and an RLC SDU.

[0125] The delivery delay of different data packets may be calculated based on the protocol entity of the UE or the to-be-measured object.

[0126] In the embodiments of the present disclosure, it is able to calculate the delay of different data packets, thereby to improve the delay calculation flexibility.

[0127] In another possible embodiment of the present disclosure, the downlink data packets for the calculation of the proportion may include: one downlink data packet among the downlink data packets which have been received repeatedly within the time period; or the downlink data packets received within the time period and located in the reordering window, and the downlink data packets located within the reordering window but ignored due to the expiration of the reordering timer at the PDCP layer. A reordering delay of the ignored downlink data packet may be a time value of the reordering timer, and the reordering window may be a data packet sequence window.

[0128] The calculation of the proportion may refer to that in the embodiments as shown in Figs.6 and 7 with a same beneficial effect, which will not be particularly defined herein.

[0129] In a possible embodiment of the present disclosure, in the embodiments of the present disclosure, the uplink data packets for the calculation of the proportion may include an uplink data packet with a shortest delivery delay when the uplink data packet has been received repeatedly within the time period.

[0130] In this regard, during the calculation of the proportion of the uplink data packets with the delivery delay, for the uplink data packet that has been received repeatedly, the shortest delivery delay may be taken as the delivery delay of the uplink data packet, so as to ensure the accuracy of the calculated proportion.

[0131] Step 905: transmitting the calculated proportion to the base station, so that the base station performs the radio resource configuration based on the proportion.
