[0043] 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.

[0044] Fig.1 shows a network to which the scheme in the embodiments of the present disclosure is applicable. As shown in Fig.1, the network includes a UE 11 and a network side device 12. The UE 11 may be a terminal device such as 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 types of the UE 11 will not be particularly defined herein. The network side device 12 may be a base station, e.g., a micro base station, a Long Term Evolution (LTE) evolved Node B (eNB), or 5th-Generation (5G) New Radio (NR) NB, or a small base station (e.g., a Low Power Node (LPN) pico base station, or a femto base station), or an Access Point (AP). In addition, the base station may also be a network node consisting of a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be appreciated that, the types of the base station will not be particularly defined herein.

[0045] As shown in Fig.2, the present disclosure provides in some embodiments a measurement gap determination method which includes: Step 201 of receiving, by a UE, measurement configuration information transmitted from a network side device, the measurement configuration information being measurement configuration information of one or more SS blocks actually transmitted on at least one BWP, the UE operating at a BWP on which no SS block is transmitted during the reception of the measurement configuration information; Step 202 of determining, by the UE, one or more measurement gaps for the measurement of the one or more SS blocks on the at least one BWP in accordance with the measurement configuration information; and Step 203 of measuring, by the UE, the one or more SS blocks on the at least one BWP in the one or more measurement gaps.

[0046] The at least one BWP may include other BWPs in a same component carrier as a BWP at which the UE operates.

[0047] The measurement configuration information may be an index, a frequency position or a time-domain position of each SS block, which will not be particularly defined herein.

[0048] In the embodiments of the present disclosure, the UE May determine a transmission position of each SS block in accordance with the measurement configuration information of the SS block, and then determine the one or more measurement gaps for the SS block. It should be appreciated that, the actually-transmitted SS block may be understood as an SS block actually transmitted on the BWP. In the embodiments of the present disclosure, a transmission timing of the one or more SS blocks will not be particularly defined, e.g., the one or more SS blocks may be transmitted after Step 202.

[0049] In addition, in the embodiments of the present disclosure, the UE may be a narrow-band UE, and the narrow-band UE may be a UE operating at one or more BWPs.

[0050] When receiving the measurement configuration information, the UE may operate at the BWP on which no SS block is transmitted, and receive the measurement configuration information of the BWP on which the SS block is actually transmitted from the network side device. In the embodiments of the present disclosure, the network side device may configure a plurality of BWPs for each carrier in a semi-static manner, and each BWP may be configured to transmit or not transmit the SS block. The narrow-band UE may be configured to operate at a serving BWP on which no SS block is transmitted.

[0051] The determining the one or more measurement gaps for the measurement of the one or more SS blocks on the at least one BWP in accordance with the measurement configuration information may include determining, by the UE, a transmission position of each SS block actually transmitted on the at least one BWP in accordance with the measurement configuration information, and determining the one or more measurement gaps for the measurement of the actually-transmitted SS blocks.

[0052] Through the above steps, the UE may determine the one or more measurement gaps for the measurement of the one or more SS blocks on the at least one BWP in accordance with the measurement configuration information of the one or more SS blocks. As a result, it is able to set the measurement gaps merely at time-domain positions where the SS blocks are actually transmitted and not set the measurement gaps at time-domain positions where no SS block is actually transmitted, i.e., to reduce the quantity of the measurement gaps, thereby to prevent the service for the UE from being interrupted as possible, and improve the communication performance of the UE.

[0053] In a possible embodiment of the present disclosure, the measurement configuration information of the one or more SS blocks actually transmitted on the at least one BWP may include measurement configuration information of N SS blocks in M SS blocks actually transmitted on the at least one BWP, the N SS blocks may be first N SS blocks in the M SS blocks ranked in a descending order of detection probabilities, the detection probabilities may be detection probabilities of the UE for the SS blocks, N is an integer greater than or equal to 1, and M is an integer greater than or equal to N.

[0054] The M SS blocks may be SS blocks possibly detected by the UE, e.g., beam directions for the transmission of the M SS blocks may cover a position of the UE. In the embodiments of the present disclosure, the network side device may estimate the SS blocks possibly detected by the UE in accordance with the beam directions for providing data services for the UE and the beam directions configured on the other BWPs for actually transmitting the SS blocks. For example, the network side device may determine the position of the UE in accordance with the beam directions for providing the data services for the UE, determine a correspondence between the beam directions configured on the other BWPs for the actually transmitting the SS blocks and the position of the UE, so as to determine the corresponding SS blocks possibly detected by the UE. Then, the network side device may select the first N SS blocks from the SS blocks possibly detected by the UE and ranked in a descending order of the detection probabilities. The first N SS blocks may be SS blocks most possibly detected by the UE and selected by the network side device in accordance with the beam directions for actually transmitting the SS blocks and the position of the UE.

[0055] In the embodiments of the present disclosure, merely the measurement configuration information of the N SS blocks may be transmitted to the UE, so it is able to further reduce the quantity of the measurement gaps for the UE.

[0056] In a possible embodiment of the present disclosure, the measurement configuration information may include at least one of an index of each of the at least one BWP on which the SS block is actually transmitted, a frequency position of each of the at least one BWP on which the SS block is actually transmitted, and a transmission configuration of each SS block actually transmitted on each of the at least one BWP. The transmission configuration may include at least one of an index of each actually-transmitted SS block in a SS block set, a time-domain position of each actually-transmitted SS block in the SS block set, a transmission period of the SS block set, a time offset of the SS block set, a carrier spacing of each SS block, and a CP of each SS block. The SS block set may be a SS block set to which each SS block actually transmitted on the at least one BWP belongs.

[0057] The index of each of the at least one BWP may be an index of each BWP in a component carrier where the BWP at which the UE operates and on which no SS block is transmitted is located, and the frequency position may also be a frequency position in the component carrier.

[0058] The SS block set may also be called as an SS burst set.

[0059] It should be appreciated that, in the embodiments of the present disclosure, when the measurement configuration information merely includes the indices, the UE May determine the frequency position and the transmission configuration in accordance with a pre-acquired correspondence among the indices, the frequency positions and the transmission configurations. In addition, when the measurement configuration information merely includes the frequency position, the UE may determine the index and the transmission configuration in accordance with the pre-acquired correspondence. When the measurement configuration information merely includes the transmission configuration, the UE may determine the index and the frequency position in accordance with the pre-acquired correspondence. Identically, the transmission configuration may also merely include at least one of the index or the time position of each actually-transmitted SS block in the SS block set, the transmission period of the SS block set, the time offset of each SS block set, the carrier spacing of each SS block, and the CP of each SS block, which will not be particularly defined herein.

[0060] In addition, the measurement configuration information may be notified by the network side device to the UE through broadcasting system information or through UE-specific Radio Resource Control (RRC) signaling, e.g., through Remaining Minimum System Information (RMSI) or Other System Information (OSI).

[0061] In the embodiments of the present disclosure, the UE may accurately determine the at least one BWP and the transmission configuration of each SS block actually transmitted on the at least one BWP in accordance with the measurement configuration information, and then accurately determine the one or more measurement gaps for the measurement of each actually-transmitted SS block, so as to further reduce the quantity of the measurement gaps for the UE.

[0062] In a possible embodiment of the present disclosure, the measurement configuration information may further include at least one of an index table of the BWPs to be measured by the UE, a SS block set to be measured by the UE in each BWP in the index table, an RRM measurement period of each BWP in the index table, a start time of the RRM measurement for each BWP in the index table, and a stop time of the RRM measurement for each BWP in the index table, and a measurement report period.

[0063] In the embodiments of the present disclosure, through the additional measurement configuration information, it is able to facilitate the UE to further reduce the quantity of the measurement gaps. This is because, the UE may determine the measurement gaps in which the SS blocks needs to be actually transmitted by the network side device in a more accurate manner in accordance with the additional measurement configuration information.

[0064] In a possible embodiment of the present disclosure, the determining, by the UE, the one or more measurement gaps for the measurement of the one or more SS blocks on the at least one BWP in accordance with the measurement configuration information may include: when the at least one BWP includes one BWP, determining, by the UE, a measurement gap pattern for the measurement of the one or more SS blocks on the BWP in accordance with the measurement configuration information, the measurement gap pattern including at least one local measurement gap of the BWP; or when the at least one BWP includes at least two BWPs, determining, by the UE, measurement gap patterns for the measurement of the one or more SS blocks on the at least two BWPs in accordance with the measurement configuration information, the measurement gap patterns including a measurement gap pattern of each of the at least two BWPs, and the measurement gap pattern of each BWP including at least one local measurement gap of the BWP.

[0065] When the at least one BWP includes one BWP, it may be understood as that the UE is configured to measure the SS blocks on merely one BWP, and when the at least one BWP includes at least two BWPs, it may be understood as that the UE is configured to measure the SS blocks on a plurality of BWPs.

[0066] When the measurement gap pattern includes at least one local measurement gap of the BWP, the measurement gap pattern may consist of at least one local measurement gap of the BWP. The measurement gap pattern of each BWP may include a measurement gap pattern for the measurement of the SS block on the BWP.

[0067] In addition, the measurement gap pattern may be determined within the transmission period of the SS block, and the network side device may actually transmit one or more SS blocks within one local measurement gap. For example, the local measurement gap may be equal to a sum of a transmission time of T SS blocks and a tuning time at each of two sides of the T SS blocks, where T is an integer greater than or equal to 1, and when T is greater than 1, the T SS blocks may be consecutive in a time domain.

[0068] The tuning time may be a Radio Frequency (RF) tuning time, e.g., the RF tuning time may be set as X (X is greater than or equal to 1) Orthogonal Frequency Division Multiplexing (OFDM)) symbols. The transmission time of the SS block may be 4 or 5 symbols, which will not be particularly defined herein. As sown in Fig.3, taking one BWP as an example, within the transmission period of the SS block set (here, the transmission period of the SS block set may also be called as the transmission period of the SS block, because they are identical), there are eight candidate transmission positions for the SS blocks, i.e., one SS block set includes eight candidate transmission positions for the SS blocks, and there are merely five actually-transmitted SS blocks. Hence, the measurement gap pattern on the BWP may include a local measurement gap 1 and a local measurement gap 2.

[0069] In the embodiments of the present disclosure, the local measurement gaps and the corresponding measurement gap patterns may be determined accurately, so it is able to further reduce the quantity of the measurement gaps.

[0070] In a possible embodiment of the present disclosure, no data service may be provided by the network side device for the UE in the one or more measurement gaps.

[0071] In this regard, the measurement of the SS blocks may not be adversely affected by the data service, so as to improve the measurement performance.

Next, the UE may determine the one or more measurement gaps for the measurement of the one or more SS blocks on the at least one BWP in accordance with the measurement configuration information. Then, the UE may measure the one or more SS blocks on the at least one BWP in the one or more measurement gaps. The one or more measurement gaps may be determined merely in accordance with the measurement configuration information of the one or more SS blocks on the at least one BWP, as compared with the related art where periodical measurement gaps are provided, it is able to reduce the quantity of the measurement gaps.
