    BACKGROUND



    [0002] With the development of communication technologies, researches on 5th Generation (5G) have been made. Radio access of 5G is called New Radio (NR). In an NR/5G system, due to application of multiple beams technology, in order for User Equipments (UE) to be successfully paged, a network side sends a paging message to the UEs in a beam sweeping manner. That is, the network side needs to send the paging message on different analog beams. When the number of beams need to be swept is N, the network side needs to repeatedly send the paging message for N times, which may increase a paging delay. Furthermore, if a single paging message may not complete the paging for all UEs at one time, a plurality of paging messages need to be sent, which, together with the N beams need to be swept, may further increase the paging delay.

    SUMMARY

    DETAILED DESCRIPTION



    [0022] For making the characteristics and technical contents of the embodiments of the disclosure understood in more detail, implementation of the embodiments of the disclosure will be described below in combination with the drawings in detail. The drawings are only adopted for description as references and not intended to limit the embodiments of the disclosure.

    [0023] In the current LTE related art, in a system, one PDSCH is scheduled by DCI sent through a Physical Downlink Control channel (PDCCH) which is scrambled by a Paging-Radio Network Temporary Identity (P-RNTI), and a single PDSCH carries one paging message. The paging message may include paging notifications for a plurality of UEs. Based on this, in a 5G/NR system, according to the technical solutions of the embodiments of the disclosure, a plurality pieces of DCI may be sent at the same time, although a single piece of DCI still only allocates and schedules one PDSCH to carry one paging message, if the paging message still includes paging notifications for a plurality of UEs, more users may be notified within the same time, compared with that in the current LTE related art. In addition, the UE may also be scheduled outside a minimum UE bandwidth range to receive the PDSCH, such that scheduling opportunities are increased by increasing frequency-domain resources available for paging, which may further reduce a paging delay.

    [0024] Based on the above contents, the technical solutions of the embodiments of the disclosure will be described below through a plurality of atypical embodiments.

    Embodiment 1



    [0025] Referring to FIG. 1, an information transmission method provided in the embodiment of the disclosure is illustrated. The method may be applied to a network-side device paging UE, for example, a gNB in 5G. The method may include the following steps.

    [0026] In S101, a paging message is sent according to information associated with at least one target UE to which the paging message needs to be sent, wherein paging messages corresponding to target UEs with same information are carried on a same PDSCH.

    [0027] It is to be noted that, at a present moment, the network-side device, when sending the paging messages, may encapsulate the paging messages, which correspond to the target UE with the same information, into the same DCI. And then, if a plurality pieces of DCI may be sent at the same time, multiple PDSCHs may be sent within the same time and more users may be notified, such that a paging delay may be reduced.

    [0028] For the technical solution in FIG. 1, the information associated with the target UE includes any one of:
    a P-RNTI corresponding to the target UE, a Control Resource SET (CORESET) corresponding to the target UE or a search space corresponding to the target UE.

    [0029] Preferably, for the information, all target UEs may be associated with respective P-RNTIs, CORESETs or search spaces according to attribute parameters of the UEs.

    [0030] During specific implementation, all UEs may be classified according to the attribute parameters of the UEs. After at least one UE category is obtained, a P-RNTI, CORESET or search space is set for each UE category. For example, the attribute parameter of the UE may include at least one of: attribute parameters, through which the UE may be classified according to a specific classification strategy, of the UE such as an identifier of the UE, the category of the UE and capability information of the UE.

    [0031] Through the above specific implementation process, it may be obtained that a corresponding relationship between the UE and the information associated with the UE may be as follows. A single target UE only corresponds to a single P-RNTI, CORESET or search space; and a single P-RNTI, CORESET or search space corresponds to at least one target UE. As shown in FIG. 2, the information is the P-RNTI, the number of the UEs is 5. It may be obtained by classification according to the attribute parameters of the UEs that UE#1, UE#3 and UE#4 correspond to the same P-RNTI#1, and that UE#2 and UE#5 correspond to the same P-RNTI#2.

    [0032] Based on the information associated with the target UE, preferably, the technical solution shown in FIG. 1 may further include a process of notifying the information to the UE, and specifically including the following operations.

    [0033] A P-RNTI, CORESET or search space corresponding to the UE is notified to the UE through a system message, a broadcast message or Remaining Minimum System Information (RMSI).

    [0034] Or, a candidate set of P-RNTIs, CORESETs or search spaces corresponding to the UE is notified to the UE through the system message, the broadcast message or the RMSI.

    [0035] Or, a P-RNTI, CORESET or search space corresponding to the UE is notified to the UE through dedicated signaling.

    [0036] Or, the candidate set of P-RNTIs, CORESETs or search spaces corresponding to the UE is notified to the UE through the dedicated signaling.

    [0037] Or, the P-RNTI corresponding to the UE or the candidate set of the P-RNTIs corresponding to the UE is determined according to provisions of a set communication protocol.

    [0038] It is to be noted that sending the candidate set of P-RNTIs, CORESETs or search spaces corresponding to the UE, to the UE may enable the UE to select the P-RNTI, CORESET or search space corresponding to the UE from the candidate set.

    [0039] For the technical solution illustrated in FIG. 1, the operation that the paging messages are sent according to the information associated with the at least one target UE to which the paging message needs to be sent includes the following operation.

    [0040] The paging messages, corresponding to the target UEs with the same information, of all paging messages are carried on the same PDSCH, physical DCI corresponding to each PDSCH corresponding to the information corresponding to the target UE.

    [0041] For the above contents, it can be understood that, taking the P-RNTI as an example, the network-side device determines the paging messages required to be sent according to the target UEs presently required to be paged. Then the network-side device may send, according to different target UEs, at least one PDSCH carrying the paging messages at the same time, such that there may be DCIs in an amount the same as the number of the PDSCHs, and each piece of DCI corresponds to a different P-RNTI, that is, different target UEs may be distinguished.

    [0042] For the UE, the UE may detect, according to the P-RNTI corresponding to the UE, whether the DCI sent by a network side includes DCI sent to the UE itself at its own Paging Occasion (PO). Therefore, for the target UE, even though the network-side device sends a plurality of pieces of DCI at the same time, each target UE still only needs to monitor one piece of DCI, which avoids increase of the processing complexity of a UE side. However, for the network-side device, more paging messages may be sent at the same time, such that the paging delay may be reduced when relatively more UEs need to be paged. In addition, when the information associated with the UE is notified through a message configured by a system, the network may flexibly configure, according to states of the UEs in the current network, a few pieces of information to be used to distinguish a plurality of UEs.

    [0043] For the technical solution illustrated in FIG. 1, by scheduling a frequency-domain resource of the PDSCH, scheduling a frequency-domain resource required by the UE to receive PDSCH is implemented, such that a requirement of compressing time resources by use of more frequency-domain resources may be met, and the paging relay is reduced. Therefore, the method further includes that: a frequency-domain resource of the PDSCH is scheduled according to a set scheduling strategy, and scheduling indication information is generated. Specifically, the following specific implementation modes are atypically and exemplarily included.

    Specific implementation mode 1



    [0044] A frequency-domain bandwidth for transmission of the PDSCH carrying the paging messages is scheduled to be less than or equal to a minimum bandwidth. A frequency-domain position for transmission of the PDSCH carrying the paging messages is scheduled within a present minimum frequency-domain range of the target UE. The scheduling indication information is generated, the frequency-domain bandwidth, indicated in the scheduling indication information, of the PDSCH being less than or equal to the minimum bandwidth, and the frequency-domain position of the PDSCH being within the present minimum frequency-domain range of the target UE.

    [0045] As illustrated in FIG. 3, taking two pieces of DCI to schedule two PDSCHs as an example, if the frequency-domain bandwidth of the PDSCH is scheduled to be less than or equal to the minimum bandwidth, it may be understood that the minimum bandwidth is a minimum UE bandwidth specified in a protocol. When the frequency-domain position of the PDSCH carrying the paging messages is scheduled within the present minimum frequency-domain range of the target UE, all the UEs in an idle state may directly receive the paging messages.

    [0046] However, it is to be noted that, in a 5G/NR system, UE additionally has an inactive state, besides the idle state and a connected state. A terminal in the inactive state is only connected with an access network, but is not connected with a core network. Therefore, not all the UEs need to be paged are in the idle state, and furthermore, not all the target UEs' present bandwidths are within the minimum UE bandwidth. Based on this, the following specific implementation mode 2 and specific implementation mode 3 are provided.

    Specific implementation mode 2



    [0047] The frequency-domain bandwidth for transmission of the PDSCH carrying the paging messages is scheduled to be less than or equal to the minimum bandwidth.

    [0048] Part of the frequency-domain position for transmission of the PDSCH carrying the paging messages are scheduled within the present minimum frequency-domain range of the target UE, and the other part of the frequency-domain position of the PDSCH are scheduled outside the present minimum frequency-domain range of the target UE. Or, the frequency-domain position of the PDSCH is scheduled outside the present minimum frequency-domain range of the target UE.

    [0049] The scheduling indication information is generated. The frequency-domain bandwidth, indicated in the scheduling indication information, of the PDSCH is less than or equal to the minimum bandwidth. Part of the frequency-domain position of the PDSCH is within the present minimum frequency-domain range of the target UE, and the other part of the frequency-domain position of the PDSCH is outside the present minimum frequency-domain range of the target UE. Or, the indicated frequency-domain bandwidth of the PDSCH is less than or equal to the minimum bandwidth and the frequency-domain position of the PDSCH is outside the present minimum frequency-domain range of the target UE.

    [0050] Furthermore, if the present bandwidth of the UE is the minimum bandwidth, the target UE needs to tune its own Radio Frequency (RF) parameter to receive the PDSCH. Thus, a time interval meeting a certain condition needs to be set between the DCI and the PDSCH, to ensure enough time for the UE to tune RF and demodulate the PDSCH. Therefore, the method further includes the following operation.

    [0051] A time interval between the DCI and the PDSCH is set according to a set time interval setting strategy. Correspondingly, the DCI may indicate the time interval between the DCI and the PDSCH.

    [0052] As illustrated in FIG. 4, a frequency-domain bandwidth of a PDSCH which is scheduled by DCI transmitted through a PDCCH#1 is less than or equal to the minimum bandwidth, and a frequency-domain position of the PDSCH is outside the present minimum frequency-domain range of the target UE. A frequency-domain bandwidth of the PDSCH which is scheduled by DCI transmitted through a PDCCH#3 is the minimum bandwidth, part of a frequency-domain position of the PDSCH is within the present minimum frequency-domain range of the target UE, and the other part of the frequency-domain position of the PDSCH is outside the present minimum frequency-domain range of the target UE.

    [0053] According to the specific implementation mode, more frequency-domain resources may be used, such that more time resources are reduced, and the paging delay is reduced.

    Specific implementation mode 3



    [0054] A frequency-domain bandwidth for transmission of part of the PDSCH carrying the paging messages is scheduled to be less than or equal to an actual bandwidth or reported bandwidth of the target UE.

    [0055] It is to be noted that the reported bandwidth may be supported bandwidth information directly reported by the UE. For example, the UE directly reports that the supported bandwidth is 20MHz, then the network-side device may send the paging message to the UE within the reported 20MHz bandwidth. Or, the reported bandwidth may be which bandwidth that can be supported by the UE. For example, assuming that the system specifies three bandwidths for certain transmissions, and B1<B2<B3, then the UE may report that B2 in the three bandwidths is supported.

    [0056] The scheduling indication information is generated, the frequency-domain bandwidth, indicated in the scheduling indication information, of the part of the PDSCH being less than or equal to the actual bandwidth or reported bandwidth of the target UE.

    [0057] As illustrated in FIG. 5, a bandwidth of a PDSCH which is scheduled by DCI transmitted through a PDCCH#1 is greater than the minimum bandwidth, but less than or equal to the actual bandwidth or reported bandwidth of the target UE. It is to be noted that, in a practical application process, bandwidths of many UEs may be greater than the minimum bandwidth, but may not exceed their actual bandwidths or reported bandwidths. Based on that the frequency-domain bandwidth for transmission of the part of the PDSCH is scheduled to be less than or equal to the actual bandwidth or reported bandwidth of the target UE, for supporting paging transmission of this form, the method further includes the following operation.

    [0058] An actual bandwidth capability of the target UE or a part of bandwidth capability that may be supported by the UE is interacted with other network-side devices. It may be understood that, when the network-side device in the embodiment is the gNB, other network-side devices may be network elements in a core network.

    [0059] Through the elaborations about the technical solutions of the embodiment, a plurality pieces of DCI are sent at the same time. Although only one PDSCH is allocated and scheduled to carry a paging message for a single piece of DCI, if the paging message still includes paging notifications for a plurality of UEs, more users may be notified within the same time, compared with the conventional LTE related art, such that the paging delay may be reduced. In addition, the UE is scheduled outside the minimum UE bandwidth range to receive the PDSCH, such that frequency-domain resources available for paging are increased to increase scheduling opportunities, and the paging delay may further be reduced.

    Embodiment 2



    [0060] Based on the same inventive concept as the abovementioned embodiment, referring to FIG. 6, a method for information transmission provided in the embodiment of the disclosure is illustrated. The method is applied to UE. The method includes the following steps.

    [0061] In S601, a paging message corresponding to the UE is received according to information associated with the UE.

    [0062] For the technical solution illustrated in FIG. 6, the information includes at least one of:
    a P-RNTI corresponding to the UE, a CORESET corresponding to the UE or a search space corresponding to the UE.

    [0063] During specific implementation, all the UEs may be classified according to their own attribute parameters, and each UE category may have corresponding information, for example, a P-RNTI, a CORESET or a search space. For example, the attribute parameter of the UE may include at least one of: attribute parameters, through which the UE may be classified according to a specific classification strategy, of the UE such as an identifier of the UE, the category of the UE and capability information of the UE. Thus it may be seen that a corresponding relationship between the UE and the information may be as follows: a single UE only corresponds to a single P-RNTI, CORESET or search space; and a single P-RNTI, CORESET or search space corresponds to at least one UE.

    [0064] Based on the information associated with the UE, a process of notifying the information associated with the UE may further be included, and specifically including the following operations.

    [0065] The P-RNTI, CORESET or search space corresponding to the UE is determined through a system message, a broadcast message or RMSI.

    [0066] Or, a candidate set of the P-RNTIs, CORESETs or search spaces corresponding to the UE is determined through the system message, the broadcast message or the RMSI.

    [0067] Or, the P-RNTI, CORESET or search space corresponding to the UE is determined through dedicated signaling.

    [0068] Or, the candidate set of the P-RNTIs, CORESETs or search spaces corresponding to the UE is determined through the dedicated signaling.

    [0069] Or, the P-RNTI corresponding to the UE or the candidate set of the P-RNTIs corresponding to the UE is specified according to a set communication protocol.

    [0070] It may be understood that the UE may select its own P-RNTI, CORESET or search space from the candidate set.

    [0071] For the technical solution illustrated in FIG. 6, the operation that the paging message corresponding to the UE is received according to the information associated with the UE may specifically include the following operations.

    [0072] DCI is received according to the information.

    [0073] A PDSCH is received according to the DCI.

    [0074] The paging message is acquired from the PDSCH.

    [0075] In the above implementation mode, the operation that the DCI is received according to the information includes the following operation.

    [0076] At a PO of the UE, the DCI sent by a network side is detected based on the information associated with the UE, and the DCI is received.

    [0077] With reference to the technical solution of the foregoing embodiment, since the network side schedules a resource of the PDSCH, a specific implementation process that the PDSCH corresponding to the DCI is received according to scheduling indication information, carried in the DCI, of the PDSCH may atypically and exemplarily include the following specific implementation modes.

    Specific implementation mode 1



    [0078] The PDSCH is received within a present minimum frequency-domain range of the UE according to a minimum bandwidth.

    Specific implementation mode 2



    [0079] The PDSCH is received within the present minimum frequency-domain range of the UE and outside the present minimum frequency-domain range of the UE according to the minimum bandwidth.

    [0080] Or, the PDSCH is received outside the present minimum frequency-domain range of the UE according to the minimum bandwidth.

    [0081] Furthermore, if a present bandwidth of the UE is the minimum UE bandwidth, the UE needs to tune its own RF parameter to receive the PDSCH, and thus a time interval meeting a certain condition needs to be set between a PDCCH and the PDSCH, to ensure enough time for the UE to tune RF and demodulate the PDSCH. Therefore, after the DCI is received according to the information, the method further includes the following operation.

    [0082] If a present bandwidth of the UE is within the minimum frequency-domain range, RF is tuned within a time interval indicated by the scheduling indication information of the PDSCH.

    Specific implementation mode 3



    [0083] Part of the PDSCH is received according to a bandwidth less than or equal to an actual bandwidth or reported bandwidth of the UE.

    [0084] It may be understood that the above three specific implementation modes correspond to the three specific implementation modes for scheduling the resource of the PDSCH in the foregoing embodiment, and elaborations about the detailed contents are omitted in the embodiment.

    Embodiment 3



    [0085] Based on the same inventive concept as the foregoing embodiments, referring to FIG. 7, a composition of a network-side device 70 provided in the embodiment of the disclosure is illustrated. The network-side device 70 includes a sending part 701, configured to send a paging message according to information associated with at least one target UE to which the paging message needs to be sent, the paging messages corresponding to the target UEs with the same information being carried on the same PDSCH.

    [0086] In the solution, the information associated with the target UE includes any one of:

    [0089] In the solution, the sending part 701 is further configured to schedule a frequency-domain resource of the PDSCH according to a set scheduling strategy and generate scheduling indication information.

    generate the scheduling indication information, the frequency-domain bandwidth, indicated in the scheduling indication information, of the PDSCH being less than or equal to the minimum bandwidth, and the frequency-domain position of the PDSCH being within the present minimum frequency-domain range of the target UE.

    [0091] In the solution, the sending part 701 is specifically configured to:
