DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the embodiments of the present application will be described in conjunction with the drawings. It should be noted that, if not in conflict, the embodiments of the present application and the features therein can be combined with each other in any manner.

[0038] 1 is a message flow chart of a radio resource configuration method according to an embodiment of the present application. As shown in FIG. 1, the radio resource configuration method applied to a next-generation NodeB (gNB) includes:

[0039] At S110, time sensitive communication (TSC) service indication information is received. The TSC service indication information includes a TSC clock accuracy indication or an indication of whether it is a TSC service.

[0040] At S120, the clock information is transmitted. The clock information is clock information that is generated based on TSC service indication information or an indication that the base station does not support clock distribution.

[0041] In order to achieve accurate clock synchronization between the base station and the radio access network, the base station needs to distribute accurate clock information to the terminal UE. In the embodiment of the present application, the distribution of accurate clock information is performed by the user equipment (UE) or the access and mobility management (AM) system. Sent from the Access and Mobility Management Function (AMF) module It may be triggered according to a request, for example, the UE sends TSC service indication information to the gNB, or the AMF sends TSC service indication information to the gNB.

[0042] In one embodiment, the step of receiving the TSC service indication information includes one of the following manners: receiving the TSC service indication information sent by the UE, receiving the TSC service indication information sent by an Access and Mobility Management Function (AMF) module, or receiving the TSC service indication information sent by the second base station through dedicated signaling.

[0043] For example, in S110, the gNB receives TSC service indication information from the UE or TSC service indication information from the AMF. In S120, the gNB sends precise clock information to the UE to achieve precise clock synchronization between the gNB and the radio access network.

[0044] In one embodiment, the TSC service indication information may be a TSC clock accuracy indication indicating the clock accuracy requirement of the service carried by the UE. In another embodiment, the TSC service indication information may be an indication of whether the service carried by the UE is a TSC service. In the above two embodiments, the clock synchronization requirement of the service carried by the user equipment (UE) is indicated through the TSC service indication information.

[0045] In one embodiment, the clock information includes a designated System Frame Number (SFN) and a time of a designated SFN endpoint boundary generated based on the TSC service indication information.

[0046] The clock information is clock information with an accuracy of less than 1 / 2. The gNB can obtain the clock synchronization requirements of the service carried by the UE based on the received TSC service indication information.

[0047] In one example, the gNB obtains its own accurate clock information, for example, the time of a specified SFN endpoint boundary. The clock information is generated based on the accuracy of the clock information corresponding to the clock synchronization requirements of the service carried by the UE.

[0048] In another example, if the gNB cannot obtain relevant information or cannot generate accurate clock information, an indication that the base station does not support clock distribution is generated to indicate that the base station does not support accurate clock information synchronization.

[0049] In one embodiment, receiving the TSC service indication information sent by the UE includes one of the following manners: receiving the TSC service indication information sent by the UE and carried by a radio link control (RLC) status package; receiving the TSC service indication information sent by the UE and carried by a medium access control control element (MAC-CE); receiving the TSC service indication information sent by the UE and carried by a medium access control (MAC) preamble; receiving the TSC service indication information sent by the UE and carried by a packet data convergence protocol (PDCP) status package; or receiving the TSC service indication information sent by the UE and carried by a radio resource control (RRC) message.

[0050] The TSC service indication information sent by the UE to the gNB can be in the following manners: RLC status package, MAC CE, MAC preamble, PDCP status package, Or it may be carried by one of the RRC messages. Thus, the gNB receives the TSC service indication information sent by the UE through one of the above-mentioned schemes.

[0051] When the TSC service indication is carried by the RLC status package or the PDCP status package, the TSC service indication information in the RLC status package or the TSC service indication information in the PDCP status package needs to be predefined by the standard.

[0052] If the TSC service indication is carried by a MAC CE, the format of the MAC CE carrying the TSC service indication needs to be predefined.

[0053] If the TSC service indication is carried by the MAC preamble, the base station needs to broadcast the preamble resources configured for the TSC service type. When a UE carrying a TSC service selects a preamble resource for the TSC service type, the UE is considered to request a TSC service resource from the base station.

[0054] If the TSC service indication is carried by an RRC message, the RRC message includes at least one of an RRCSystemInfoRequest, an RRC RRCSetupRequest, an RRCResumeRequest, an RRCResumeRequest1, or an RRCReestablishmentRequest.

[0055] In one embodiment, the step of receiving the TSC service indication information sent by the AMF includes one of the following methods: receiving the TSC service indication information carried by common signaling of the NG interface, or receiving the TSC service indication information carried by UE-dedicated signaling of the NG interface.

[0056] The TSC service indication information sent by the AMF to the gNB may be carried by UE-specific signaling of the NG interface or through common signaling of the NG interface. Thus, the gNB receives the TSC service indication information sent by the AMF through one of the aforementioned methods. The NG interface is an interface between the radio access network and the fifth generation mobile communication technology (5G) core network.

[0057] In one embodiment, the clock information transmitted to the user equipment (UE) is in the following ways: RLC status package, MAC CE, downlink control information. The QoS may be conveyed through one of the following: a QoS Configuration Information (DCI), a PDCP status package, downlink RRC signaling, or a broadcast message.

[0058] When the precise clock information is carried by the RLC state package or the PDCP state package, the precise clock information in the RLC state package or the precise clock information in the PDCP state package needs to be predefined by the standard.

[0059] If the TSC service indication is carried by the MAC CE, the format of the MAC CE that carries the accurate clock information needs to be predefined.

[0060] If precise clock information is carried by a DCI, the format of the DCI carrying the precise clock information needs to be predefined.

[0061] If accurate clock information is carried by the RRC message, the RRC message , an instruction to switch from new radio to evolved universal terrestrial radio access network (E-UTRAN) (MobilityFromNRCommand), RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

[0062] In the embodiment of the present application, the clock synchronization requirement of the service carried by the terminal user equipment (UE) is indicated through the time-sensitive communication (TSC) service indication information, and the accurate clock information is distributed to the UE through the base station, so as to achieve the accurate clock synchronization of the radio access network. For the service that requires strong transmission delay sensitivity, this meets the delay requirement of the service during transmission in the radio network.

[0063] In one embodiment, the step of transmitting the clock information includes a step of transmitting the clock information to the UE after the TSC service indication information transmitted by the UE is received, or, if a cell handover is not required, a step of transmitting the clock information to the UE after the TSC service indication information transmitted by the AMF is received.

As shown in FIG. 2, in one embodiment, the UE sends TSC service indication information to the gNB, triggering the gNB to generate precise clock information. The gNB sends the generated precise clock information to the UE.

[0065] 3 is a message flow chart of a radio resource configuration method according to an embodiment of the present application. As shown in FIG. 3, in one embodiment, the AMF sends TSC service indication information to the gNB and triggers the gNB to generate accurate clock information. If no cell handover is required, the gNB sends the generated accurate clock information to the UE.

[0066] In one embodiment, the step of transmitting clock information includes a step of transmitting TSC service indication information to a target base station of the handover after the TSC service indication information transmitted by the AMF is received during the cell handover process.

[0067] Figure 4 is a flow chart showing that in a radio resource configuration method according to an embodiment of the present application, a source cell broadcasts precise clock information to a target cell during a handover process. As shown in Figure 4, in one embodiment, the AMF sends TSC service indication information to a handover source gNB. In a cell handover process, the handover source gNB sends TSC service indication information to a handover target gNB. After the TSC service indication information is received, the handover target gNB sends precise clock information to the UE through broadcasting.

[0068] In one embodiment, the step of transmitting clock information includes a step of transmitting dedicated signaling carrying the TSC service indication information or dedicated signaling carrying a clock information request to the target base station of the handover after the TSC service indication information transmitted by the AMF is received during the cell handover process.

As shown in FIG. 5, in one embodiment, the AMF sends TSC service indication information to the handover source gNB. During the cell handover process, the handover source gNB sends a TSC service indication information or a precise clock information request message to the handover target gNB.

[0070] In one embodiment, the method further comprises: The TSC service indication information carried by the dedicated signaling is configured to indicate the target base station of the handover to obtain clock information of the target base station and send the clock information to the UE, or send the clock information through broadcast.

[0071] Referring to Figure 5, in this embodiment, the TSC service indication information or the precise clock information request message is configured to trigger the handover target gNB to generate dedicated signaling carrying precise clock information. After the TSC service indication information or the precise clock information request message is received, the handover target gNB sends the generated precise clock information to the handover source gNB. After the precise clock information is received, the handover source gNB generates dedicated signaling carrying the precise clock information and forwards the dedicated signaling to the UE.

[0072] In one embodiment, the step of sending the clock information includes a step of sending the clock information to the source base station of the handover after TSC service indication information sent by the source base station of the handover or a clock information request sent by the source base station of the handover is received during the cell handover process.

[0073] Referring to Figure 5, after the TSC service indication information sent by the handover source gNB or the precise clock information request message sent by the handover source gNB is received, the handover target gNB sends the generated precise clock information to the handover source gNB.

[0074] The gNB includes a centralized unit of Next Generation NodeB (gNB-CU) and a distributed unit of Next Generation NodeB (gNB-DU). In one embodiment, the precise clock information carried by the PDCP status package or the precise clock information carried by the RRC message comes from the precise clock information sent by the gNB-DU, or the gNB-CU obtains its own precise clock information.

[0075] In one embodiment, when the next generation NodeB centralized unit (gNB-CU) and the next generation NodeB distributed unit (gNB-DU) are separated, the step of receiving the TSC service indication information sent by the UE includes one of the following methods: receiving, by the gNB-DU, the TSC service indication information carried by a Radio Link Control (RLC) status package, the TSC service indication information carried by a Medium Access Control Control Element (MAC-CE), and the TSC service indication information carried by a MAC preamble sent by the UE, or receiving, by the gNB-CU, the TSC service indication information carried by a Packet Data Convergence Protocol (PDCP) status package, the TSC service indication information carried by a MAC preamble, and the TSC service indication information carried by a Radio Resource Control (RRC) message sent by the UE and forwarded by the gNB-DU.

[0076] Figure 6 is a flowchart showing that in a radio resource configuration method according to an embodiment of the present application, the TSC clock of the Uu interface requests accurate clock information transmitted through dedicated signaling. Referring to Figure 6, the UE transmits TSC service indication information to the gNB-DU. The TSC service indication information can be carried by one of the RLC status package, the MAC CE, or the MAC preamble. The gNB-DU receives the TSC service indication information through one of the aforementioned methods.

Referring to FIG. 8 and FIG. 10, the UE sends TSC service indication information to the gNB-DU. The gNB-DU sends the TSC service indication information to the gNB-CU. The TSC service indication information may be carried by a PDCP status package, a MAC preamble, or an uplink RRC message. The gNB-CU receives the TSC service indication information through one of the aforementioned methods.

[0078] In one embodiment, the step of receiving the TSC service indication information includes a step of receiving, by the gNB-DU, the TSC service indication information sent by the UE, or a step of receiving, by the gNB-CU, the TSC service indication information sent by the AMF and forwarding the TSC service indication information to the gNB-DU.

[0079] The step of transmitting clock information to the UE includes a step of transmitting, by the gNB-DU, clock information generated by the gNB-DU to the UE.

[0080] In the embodiment shown in Figure 6, the UE transmits TSC service indication information to the gNB-DU. The TSC service indication information may be carried by one of the RLC status package, the MAC CE, or the MAC preamble. The TSC service indication information may be a TSC clock accuracy indication (indicating the clock accuracy requirement of the service) or a TSC service indication (indicating whether it is a TSC service).

[0081] Referring to FIG. 6, in one embodiment, before the gNB-DU transmits the clock information to the UE, the method further includes the gNB-DU generating precise clock information based on the TSC service indication information and the clock of the specified system frame number (SFN) boundary. If the TSC service indication information is a TSC clock accuracy indication or an indication that the service carried by the UE is a TSC service, the gNB-DU generates the required precise clock information based on the clock of the specified system frame number (SFN) boundary. In another embodiment, if the gNB-DU cannot obtain the related information or cannot generate the precise clock information, the gNB-DU generates an indication that it does not support precise clock information.

[0082] In summary, the gNB-DU generates the precise clock information or an indication that the precise clock information is not supported, and then transmits the precise clock information or an indication that the precise clock information is not supported to the UE. The precise clock information or an indication that the precise clock information is not supported may be carried by the RLC status package, the MAC CE, or the DCI.

[0083] 7 is a flowchart illustrating a radio resource configuration method according to an embodiment of the present application, in which a TSC clock of an NG interface requests accurate clock information sent through dedicated signaling. In the embodiment shown in FIG. 7, receiving TSC service indication information sent by an AMF includes receiving TSC service indication information sent by an AMF, which is carried by UE dedicated signaling of an NG interface or through common signaling of an NG interface.

[0084] Referring to FIG. 7, the AMF sends TSC service indication information to the gNB-CU through UE-dedicated signaling of the NG interface. The gNB-CU sends TSC service indication information to the gNB-CU through the F1 interface. The UE transfers the TSC service indication information to the gNB-DU through UE-dedicated signaling of the NG interface.

[0085] Referring to Figure 7, in one embodiment, the gNB-DU generates precise clock information based on TSC service indication information from the terminal UE and the clock of a specified system frame number (SFN) boundary. If the TSC service indication information is a TSC clock precision indication or an indication that the service carried by the UE is a TSC service, the gNB-DU generates the required precise clock information based on the clock of a specified system frame number (SFN) boundary. If the gNB-DU cannot obtain the relevant information or cannot generate precise clock information, the gNB-DU generates an indication that it does not support precise clock information.

[0086] In summary, the gNB-DU generates the precise clock information or an indication that the precise clock information is not supported, and then transmits the precise clock information or an indication that the precise clock information is not supported to the UE. The precise clock information or an indication that the precise clock information is not supported may be carried by the RLC status package, the MAC CE, or the DCI.

[0087] In one embodiment, receiving the TSC service indication information includes receiving, by the gNB-DU, the TSC service indication information sent by the UE and forwarding the TSC service indication information to the gNB-CU, or receiving, by the gNB-CU, the TSC service indication information sent by the AMF. Sending the clock information to the UE includes generating, by the gNB-CU, dedicated signaling, sending the dedicated signaling to the gNB-DU, and sending, by the gNB-DU, the dedicated signaling to the UE.

Figure 9 is a flowchart showing that in a radio resource configuration method according to an embodiment of the present application, the TSC clock of the NG interface requests accurate clock information sent through dedicated signaling. In the embodiment shown in Figure 8, the gNB-CU receives the TSC service indication information sent by the UE and forwarded through the gNB-DU. In the embodiment shown in Figure 9, the gNB-CU receives the TSC service indication information sent by the AMF.

[0089] 8, in one embodiment, the UE sends TSC service indication information to the gNB-CU through the gNB-DU.

The uplink RRC message includes at least one of an RRCSystemInfoRequest, an RRCSetupRequest, an RRCResumeRequest1, an RRCResumeRequest, or an RRCReestablishmentRequest.

[0090] In one embodiment, the dedicated signaling carries clock information generated by the gNB-CU. In this embodiment, before the gNB-CU transmits the clock information to the gNB-DU, the method further includes the gNB-CU generating the clock information based on the TSC service indication information and a clock of a specified system frame number (SFN) boundary.

[0091] The dotted lines in FIG. 8 indicate options. In an embodiment without dotted lines, the gNB-DU transmits TSC service indication information to the gNB-CU. After the TSC service indication information is received, the gNB-CU generates precise clock information or an indication that precise clock information is not supported, and transmits the precise clock information or an indication that precise clock information is not supported to the gNB-DU. The gNB-DU then forwards the precise clock information or an indication that precise clock information is not supported to the UE. When the precise clock information is transmitted, the reference SFN corresponding to the precise clock information is carried at the same time. The step of generating precise clock information by the gNB-CU includes a step of generating the required precise clock information based on the TSC service indication information from the terminal UE and the clock at the instant of the reference SFN boundary.

[0092] In one embodiment, subject to clock synchronization between the gNB-CU and the gNB-DU, the gNB-CU obtains its own precise clock information, generates dedicated signaling carrying the precise clock information, and sends the dedicated signaling to the gNB-DU.

[0093] If the clock of the gNB-CU and the clock of the gNB-DU are not synchronized, the gNB-CU may request accurate clock information from the gNB-DU, generate dedicated signaling carrying the accurate clock information, and send the dedicated signaling to the gNB-DU.

[0094] In one embodiment, the method further includes the step of the gNB-DU transmitting clock information generated by the gNB-DU to the gNB-CU when forwarding the TSC service indication information to the gNB-CU. The gNB-CU generates dedicated signaling. The dedicated signaling carries the clock information generated by the gNB-DU.

[0095] Referring to Figure 8, this embodiment corresponds to the dotted line embodiment in Figure 8. The case shown by the dotted line indicates that after a TSC service indication is received from the UE, the gNB-DU triggers the precise clock information to be sent to the gNB-CU, or triggers an indication that the precise clock information is not supported to be generated and sent to the gNB-CU. The gNB-CU generates dedicated signaling to carry the precise clock information or to carry an indication that the precise clock information is not supported, and returns the dedicated signaling to the gNB-DU. The gNB-DU then transmits the dedicated signaling to the UE. When the gNB-DU transmits the precise clock information, the reference SFN corresponding to the precise clock information is carried at the same time. The precise clock information refers to the precise clock information at the instant of the reference SFN boundary.

[0096] Referring to Figure 8, as described above, the gNB-DU transmits precise clock information or an indication that precise clock information is not supported to the UE. The transmission may be carried by one of the PDCP status packages or downlink RRC signaling. The downlink RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

[0097] In the embodiment shown in FIG. 9, the AMF sends UE-dedicated signaling of the NG interface The UE-specific signaling of the NG interface includes at least one of paging, an initial context setup request, a UE context release command, a UE context modification response, a handover request, a path switch request confirmation, a path switch request failure, a PDU session resource setup request, or a PDU session resource modification request.

[0098] The dotted lines in FIG. 9 indicate options. In the case not shown by the dotted lines, after the TSC service indication information is received from the AMF, the gNB-CU generates precise clock information or an indication that the precise clock information is not supported, and sends the precise clock information or an indication that the precise clock information is not supported to the gNB-DU. The gNB-DU then forwards the precise clock information or an indication that the precise clock information is not supported to the UE. When the gNB-CU sends the precise clock information, the reference SFN corresponding to the precise clock information is carried at the same time. The step of generating precise clock information by the gNB-CU includes the step of generating the required precise clock information based on the TSC service indication information from the UE and the clock at the instant of the reference SFN boundary.

[0099] In one embodiment, the method further comprises: After the TSC service indication information sent by the AMF is received, the gNB-CU forwards the TSC service indication information to the gNB-DU or sends a clock information request to the gNB-DU. After the TSC service indication information or the clock information request is received, the gNB-DU sends the clock information generated by the gNB-DU to the gNB-CU. The dedicated signaling carries the clock information generated by the gNB-DU.

[0100] With reference to Figure 9, the above corresponds to the dotted embodiment of Figure 9. In the example of Figure 9, the gNB-DU sending precise clock information to the gNB-CU or generating an indication that precise clock information is not supported and sending an indication that precise clock information is not supported to the gNB-DU may be triggered through one of the following manners: after a TSC service indication is received from the gNB-CU, the gNB-DU sends precise clock information or an indication that precise clock information is not supported, or after a clock information request is received from the gNB-CU, the gNB-DU sends precise clock information or an indication that precise clock information is not supported.

[0101] In response to the TSC service indication or clock information request, the gNB-DU sends precise clock information to the gNB-CU, or generates an indication that precise clock information is not supported and sends an indication that precise clock information is not supported to the gNB-CU. The gNB-CU generates dedicated signaling carrying the precise clock information and returns the dedicated signaling to the gNB-DU. The gNB-DU then forwards the dedicated signaling to the UE. When the precise clock information is sent, the reference SFN corresponding to the precise clock information is carried at the same time. The precise clock information refers to the precise clock information at the instant of the reference SFN boundary.

[0102] In one embodiment, the step of sending, by the gNB-DU, the clock information generated by the gNB-DU to the gNB-CU after the TSC service indication information or the clock information request is received further includes:

[0103] The gNB-DU periodically generates clock information and periodically transmits the generated clock information to the gNB-CU. Alternatively, the gNB-DU generates clock information and transmits the generated clock information to the gNB-CU.

[0104] In one embodiment, the clock information may be periodically generated by the gNB-DU and periodically transmitted to the gNB-CU. In another embodiment, after each TSC service indication information is received, the gNB-DU generates the clock information once and transmits the generated clock information to the gNB-CU.

[0105] Referring to Figure 9, the gNB-DU transmits precise clock information or an indication that precise clock information is not supported to the UE. The transmission may be carried by a PDCP status package or downlink RRC signaling. The downlink RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

[0106] Figure 10 is a flowchart showing that in a radio resource configuration method according to an embodiment of the present application, the TSC clock of the Uu interface requests accurate clock information transmitted through broadcast. In the embodiment shown in Figure 10, the UE sends TSC service indication information to the gNB-DU. The TSC service indication information can be carried by a PDCP status package, a MAC preamble, or an uplink RRC message. The uplink RRC message includes at least one of RRCSystemInfoRequest, RRCSetupRequest, RRCResumeRequest1, RRCResumeRequest, RRCReestablishmentRequest, or FailureInformation.

[0107] In one embodiment, before the clock information is transmitted to the UE, the method further includes the gNB-CU transmitting the clock information carried by a system information block 9 (SIB9) and transmitting a periodic clock information broadcast indication to the gNB-DU through dedicated signaling.

[0108] Referring to Figure 10, the gNB-DU sends TSC service indication information to the gNB-CU, triggering the gNB-CU to periodically broadcast SIB9 carrying accurate clock information. In one embodiment, the indication to periodically broadcast SIB9 may be carried in SIB1. SIB1 is configured for cell access information and scheduling information of SIBs (except SIB1). SIB9 is configured for related information carrying Home eNB (HeNB).

[0109] 10, the gNB-CU carries SIB9 carrying precise clock information and periodically transmits SIB9 to the gNB-DU. Further, an instruction to periodically broadcast SIB9 carrying precise clock information is carried in downlink dedicated signaling.

[0110] In one embodiment, the method further includes: after the periodic clock information broadcast indication is received, the gNB-DU reconstructs the clock information carried in the SIB9 generated by the gNB-CU, and based on obtaining its own clock information, writes the clock information carried in the SIB9 as the time of the specified SFN endpoint boundary, and sends the SIB9 to the UE via broadcast.

[0111] Referring to Figure 10, the gNB-DU periodically broadcasts SIB9 carrying precise clock information. The precise clock information broadcast by the gNB-DU includes a designated system frame number (SFN). The gNB-DU can update the clock information in SIB9 based on the broadcast opportunity of SIB9, and then transmit the updated SIB9 to the UE through broadcast. In addition, the gNB -The DU sends an instruction to the UE to periodically broadcast SIB9 carrying accurate clock information via downlink dedicated signaling.

[0112] In one embodiment, the gNB-DU sends a periodic clock information broadcast indication of SIB9 carrying clock information to the UE through dedicated signaling.

[0113] Referring to FIG. 10, the gNB-DU periodically transmits clock information to the UE through SIB9, and at the same time transmits an instruction to periodically broadcast the SIB9 carrying the clock information to the UE. The UE reads the clock information in SIB9 to obtain an accurate system clock. The UE's reading of the clock information in SIB9 may be triggered by an instruction to periodically broadcast the SIB9 carrying the accurate clock information in the downlink dedicated signaling, or may be triggered based on the implementation behavior of the UE. For example, when an accurate system clock is required, the UE actively reads the clock information in the received SIB9 to obtain an accurate system clock. The downlink dedicated signaling includes at least one of a PDCP status package, a MAC CE, a DCI, or a downlink RRC signaling. The downlink RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

In the embodiment shown in FIG. 11, the AMF sends TSC service indication information to the gNB-CU through UE-dedicated signaling of the NG interface. The UE-dedicated signaling of the NG interface includes at least one of paging, initial context setup request, UE context release command, UE context modification response, handover request, path switch request confirmation, path switch request failure, PDU session resource setup request, or PDU session resource modification request.

[0115] Referring to FIG. 11, the gNB-CU receives TSC service indication information from the AMF, triggers the gNB-CU to send the TSC service indication information to the gNB-DU, and simultaneously triggers the gNB-CU to periodically broadcast SIB9 carrying precise clock information. In one embodiment, the indication to periodically broadcast SIB9 may be carried in SIB1. As shown by the dotted line in FIG. 11, it is optional for the gNB-CU to send the TSC service indication information to the gNB-DU. In one embodiment, the aforementioned option may be omitted. When receiving the TSC service indication information from the AMF, the gNB-CU is only triggered to periodically broadcast SIB9 carrying precise clock information.

[0116] 11, the gNB-CU carries SIB9 with precise clock information and periodically transmits SIB9 to the gNB-DU. Further, an instruction to periodically broadcast SIB9 carrying precise clock information is carried in downlink dedicated signaling.

[0117] Referring to Figure 11, after the above indication is received, the gNB-DU periodically broadcasts SIB9 carrying precise clock information. The precise clock information broadcast by the gNB-DU includes a specified system frame number (SFN). The gNB-DU can update the clock information in SIB9 based on the broadcast opportunity of SIB9. The gNB-DU can update the clock information in SIB9 based on the SI generated by the gNB-CU. The gNB-DU reconstructs the SIB9 carrier clock information, writes the SIB9 carrier clock information as the time of the specified system frame number (SFN) endpoint boundary based on the acquisition of its own clock information, and sends the SIB9 to the UE through broadcast. In addition, the gNB-DU sends an instruction to the UE to periodically broadcast the SIB9 carrying the accurate clock information through downlink dedicated signaling.

[0118] The UE reads the clock information in SIB9 to obtain an accurate system clock. The UE's reading of the clock information in SIB9 may be triggered by an instruction to periodically broadcast SIB9 carrying accurate clock information in downlink dedicated signaling, or may be triggered based on the implementation behavior of the UE. For example, when an accurate system clock is required, the UE actively reads the clock information in the received SIB9 to obtain an accurate system clock. The downlink dedicated signaling includes at least one of a PDCP status package, a MAC CE, a DCI, or a downlink RRC signaling. The downlink RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

[0119] 12 is a flowchart illustrating a radio resource configuration method according to an embodiment of the present application, in which common signaling of the NG interface requests accurate clock information transmitted through broadcast. In the embodiment shown in FIG. 12, the AMF sends TSC service indication information to the gNB-CU through common signaling of the NG interface. The common signaling of the NG interface includes at least one of an NG setup response, a RAN configuration update confirmation, an AMF configuration update, or an AMF status indication.

[0120] Referring to FIG. 12, the gNB-CU carries SIB9 carrying precise clock information and periodically transmits SIB9 to the gNB-DU. The gNB-DU periodically broadcasts SIB9 carrying precise clock information. The precise clock information broadcast by the gNB-DU includes a specified system frame number (SFN). The gNB-DU can update the clock information in SIB9 based on the broadcast opportunity of SIB9. The gNB-DU reconstructs the SIB9 carrying clock information generated by the gNB-CU, and based on the acquisition of its own clock information, writes the SIB9 carrying clock information as the time of the specified system frame number (SFN) endpoint boundary, and transmits SIB9 to the UE through broadcast.

[0121] The UE reads the clock information in SIB9 to obtain an accurate system clock. The UE's reading of the clock information in SIB9 may be triggered by an instruction to periodically broadcast SIB9 carrying accurate clock information in downlink dedicated signaling, or may be triggered based on the implementation behavior of the UE. For example, when an accurate system clock is required, the UE actively reads the clock information in the received SIB9 to obtain an accurate system clock. The downlink dedicated signaling includes at least one of a PDCP status package, a MAC CE, a DCI, or a downlink RRC signaling. The downlink RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCResume, RRCReject, or RRCSetup.

[0122] In one embodiment, the step of transmitting clock information to a user equipment (UE) is carried out in the following manner: a radio link control (RLC) status package, a medium access control control element ( The method includes transmitting the clock information in one of the following ways: a MAC-CE message, a downlink control information (DCI), a packet data convergence protocol (PDCP) status package, a radio resource control (RRC) message, or a broadcast message.

[0123] When the precise clock information is carried by the RLC state package or the PDCP state package, the precise clock information in the RLC state package or the precise clock information in the PDCP state package needs to be predefined by the standard.

[0124] If the TSC service indication is carried by the MAC CE, the format of the MAC CE that carries the accurate clock information needs to be predefined.

[0125] If precise clock information is carried by a DCI, the format of the DCI carrying the precise clock information needs to be predefined.

[0126] If the precise clock information is carried by an RRC message, the RRC message includes at least one of MobilityFromNRCommand, RRCReestablishment, RRCReconfiguration, RRCRCResume, RRCReject, or RRCSetup.

[0127] 13 is a flowchart of a radio resource configuration method applied to a UE according to an embodiment of the present application. As shown in FIG. 13, the radio resource configuration method applied to a UE according to an embodiment of the present application includes:

[0128] At S210, clock information transmitted by a base station is received. The clock information includes a specified system frame number (SFN) and a time of a specified SFN endpoint boundary generated based on the TSC service indication information. The clock information is clock information with an accuracy of less than one-half.

[0129] Referring to the embodiments shown in Figures 3, 4, 5, 7, 9, 11 and 12, the UE receives clock information sent by the base station. Based on the time of the specified SFN endpoint boundary in the clock information, accurate clock synchronization between the base station and the radio access network is achieved. For services with strong transmission delay sensitivity, this meets the delay requirements of the services during transmission in the radio network.

[0130] 14 is a flowchart of a radio resource configuration method applied to a UE according to an embodiment of the present application. As shown in FIG. 14, in one embodiment, before receiving clock information sent by a base station, S210 includes:

[0131] In S205, TSC service indication information is sent to the base station. The TSC service indication information includes a TSC clock accuracy indication or an indication of whether the service carried by the user equipment (UE) is a TSC service.

[0132] Referring to the embodiments shown in Figures 2, 6, 8, and 10, the UE sends TSC service indication information to the gNB. The gNB generates accurate clock information according to the TSC service indication information, and sends the accurate clock information to the UE.

[0133] In one embodiment, receiving the clock information transmitted by the base station includes receiving the clock information transmitted by the base station through broadcast, receiving the clock information transmitted by the base station through dedicated signaling, or receiving the clock information transmitted by the base station through dedicated signaling. The method includes one of: receiving a periodic clock information broadcast indication transmitted by the base station through the ring; and triggering the clock information transmitted by the base station through the broadcast to be received based on the clock information broadcast indication.

[0134] In the embodiment shown in Figure 8, the UE receives clock information sent by the base station through dedicated signaling. In the embodiment shown in Figure 8, the UE receives a periodic clock information broadcast indication sent by the base station through dedicated signaling, and is triggered to receive the clock information sent by the base station through broadcast according to the clock information broadcast indication.

[0135] In one embodiment, the step of transmitting the TSC service indication information to the base station includes transmitting the TSC service indication information in one of the following manners: an RLC status package, a MAC CE, a MAC preamble, a PDCP status package, or an RRC message.

[0136] The TSC service indication information sent by the UE to the gNB may be carried by one of the following manners: RLC status package, MAC CE, MAC preamble, PDCP status package, or RRC message.

[0137] When the TSC service indication is carried by the RLC status package or the PDCP status package, the TSC service indication information in the RLC status package or the TSC service indication information in the PDCP status package needs to be predefined by the standard.

[0138] If the TSC service indication is carried by a MAC CE, the format of the MAC CE carrying the TSC service indication needs to be predefined.

[0139] If the TSC service indication is carried by the MAC preamble, the base station needs to broadcast the preamble resources configured for the TSC service type. When a UE carrying a TSC service selects a preamble resource for the TSC service type, the UE is considered to request a TSC service resource from the base station.

[0140] If the TSC service indication information is carried by an RRC message, the RRC message includes at least one of an RRCSystemInfoRequest, an RRCSetupRequest, an RRCResumeRequest, an RRCResumeRequest1, or an RRCReestablishmentRequest.

[0141] For a specific implementation of the radio resource configuration method applied to the UE in the embodiment of the present application, reference may be made to the relevant description of the aforementioned radio resource configuration method applied to the base station, which will not be repeated here.

[0142] 15 is a flowchart of a radio resource configuration method applied to AMF according to an embodiment of the present application. As shown in FIG. 15, the radio resource configuration method applied to AMF according to an embodiment of the present application includes:

[0143] At S310, TSC service indication information is sent to the base station. The TSC service indication information includes a TSC clock accuracy indication or an indication of whether the service carried by the UE is a TSC service. The TSC service indication information triggers the base station to generate clock information and send the clock information to the UE.

[0144] Referring to the embodiments shown in Figures 3, 4, 5, 7, 9, 11, and 12, the AMF sends TSC service indication information to the gNB. The gNB generates accurate clock information based on the TSC service indication information and sends the accurate clock information to the UE. The clock information includes a specified system frame number (SFN) and a time of a specified SFN endpoint boundary generated based on the TSC service indication information. The clock information is clock information with an accuracy of less than one-half. The UE receives the clock information sent by the base station. Based on the time of the specified SFN endpoint boundary in the clock information, accurate clock synchronization between the base station and the radio access network is achieved. For services with strong transmission delay sensitivity, this meets the delay requirements of the service during transmission in the radio network.

[0145] In one embodiment, transmitting the TSC service indication information to the base station includes transmitting the TSC service indication information in one of the following manners: dedicated signaling of the NG interface or common signaling of the NG interface.

[0146] Referring to the embodiments shown in Figures 3, 4, 5, 7, 9, 11, and 12, the TSC service indication information sent by the AMF to the gNB may be carried by dedicated signaling of the NG interface or common signaling of the NG interface. The NG interface is an interface between the radio access network and the fifth generation mobile communication technology (5G) core network.

[0147] In one embodiment, the base station includes a gNB-CU. The sending of the TSC service indication information to the base station includes sending the TSC service indication information to the gNB-CU.

[0148] Referring to the embodiments shown in Figures 7, 9, 11, and 12, the AMF sends TSC service indication information to the gNB-CU.

[0149] For a specific implementation of the radio resource configuration method applied to AMF in the embodiment of the present application, reference may be made to the relevant description of the aforementioned radio resource configuration method applied to the base station, and will not be repeated here.

[0150] In another aspect, because IIoT services are highly delay-sensitive, radio resources are generally pre-configured based on service modes to reduce transmission delays. Services perform data transmissions on pre-configured radio resources, so that there is no need to perform resource scheduling on each transmission. Such resource pre-configuration schemes are generally called semi-persistent scheduling (SPS) in downlink scenarios and configured grant (CG) in uplink scenarios. In uplink and downlink scenarios, the operation of radio resource configuration is similar. For ease of description, uplink resource pre-configuration and downlink resource pre-configuration are respectively called semi-persistent resource configuration.

[0151] An embodiment of the present application provides a wireless resource configuration method. In order to save overload in activating or deactivating resources, semi-persistent resource configurations having the same activation or deactivation opportunity can be regarded as one semi-persistent resource configuration group.

[0152] With respect to semi-persistent resource configurations and semi-persistent resource configuration groups, the issue of activation or deactivation coupling between semi-persistent resource configuration groups and semi-persistent resource configurations needs to be considered. In one example, the semi-persistent resource configuration group method requires classifying semi-persistent resource configurations that can be activated at the same time into one group. For example, the table below shows an SPS configuration with a frequency of 60 Hz.

[0153] [Table 1]

[0154] For a service with a frequency of 60Hz, the period = 1s / 60 = 16.667ms. The period is not an integer multiple of the subframe length of 10ms, so the service period cannot be directly configured within the subframe. For example, in the data in the above table, the resource interval is 17 subframes, 17 subframes, 16 subframes, 17 subframes.... In this example, the service is divided into three SPS configurations with a period of 50ms. That is, the service frequency of 60Hz coincides with the subframes in the following configuration method. Multiple SPS configurations can be expressed as follows:

[0155] { SPS1:SPSStartSubframe=0;SPSInterval=50 subframes. SPS2:SPSStartSubframe=17;SPSInterval=50 subframes. SPS3:SPSStartSubframe=34;SPSInterval=50 subframes. } SPSStartSubframe represents the SPS start subframe. SPSInterval represents the SPS transmission interval. To correspond to the same service period, the above three SPS configurations need to be activated or deactivated at the same time.

[0156] 16 is a flowchart of a radio resource configuration method applied to a base station according to an embodiment of the present application and configured to configure a semi-persistent scheduling group. As shown in FIG. 16, the radio resource configuration method applied to a base station according to an embodiment of the present application includes:

[0157] At S410, a mapping relationship between a semi-persistent resource configuration index and a semi-persistent resource group identity is configured for the UE.

[0158] At S420, an activation command or a deactivation command is sent to the UE, and through the activation command or the deactivation command, the semi-persistent resource configuration is activated or deactivated for the semi-persistent resource group identity.

[0159] As described above, the semi-persistent resource configuration group method requires that the semi-persistent resource configurations that can be activated simultaneously are classified into one group. In S410, a mapping between the semi-persistent resource configuration index and the semi-persistent resource group identification information is performed. A relationship is established. In S420, downlink control information (DCI) can be used to transmit information of a semi-persistent resource configuration index or information of a semi-persistent resource group identity, and an activation command or a deactivation command is sent to the UE, so that the semi-persistent resource configuration is activated or deactivated for the semi-persistent resource group identity.

[0160] In one embodiment, the semi-persistent resource configuration index includes a semi-persistent scheduling (SPS) configuration index or a configuration grant (CG) configuration index.

[0161] As mentioned above, in the embodiment of the present application, the uplink resource pre-configuration and the downlink resource pre-configuration are respectively referred to as semi-persistent resource configuration.

[0162] In one embodiment, the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identification information includes a mapping relationship between one semi-persistent resource group identification information and a plurality of semi-persistent resource configuration indexes. Each semi-persistent resource configuration corresponds to a value range of at least one process identification information. The value range includes at least one process identification information. Alternatively, the value range includes a start value of the process identification information and a number of processes.

[0163] Figure 17 is a diagram illustrating the configuration of a semi-persistent scheduling group in a radio resource configuration method according to an embodiment of the present application. As shown in Figure 17, a semi-persistent resource group identity b corresponds to a semi-persistent resource configuration index 1 and a semi-persistent resource configuration index 2. That is, one semi-persistent resource group includes multiple semi-persistent resource configurations.

[0164] In one embodiment, the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identification information includes a mapping relationship between one semi-persistent resource configuration index and multiple semi-persistent resource group identification information. Each semi-persistent resource configuration corresponds to a value range of at least one process identification information. The value range includes at least one process identification information. Alternatively, the value range includes a start value of the process identification information and a number of processes.

[0165] Figure 18 is a diagram illustrating the configuration of a semi-persistent scheduling group in a radio resource configuration method according to an embodiment of the present application. As shown in Figure 18, a semi-persistent resource configuration index (SPS Config index) 2 corresponds to a semi-persistent resource group identity (SPS group identity) b and a semi-persistent resource group identity (SPS group identity) c. That is, one semi-persistent resource configuration can belong to multiple different semi-persistent resource groups.

[0166] In one embodiment, the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identity information being configured for the UE includes:

[0167] The semi-persistent resource configuration index is mapped to the semi-persistent resource group identity through MAC CE or RRC dedicated signaling.

[0168] In this embodiment, through MAC CE or RRC dedicated signaling, the base station maps an SPS configuration index to an SPS group identity, or maps a CG configuration index to a CG group identity.

[0169] For the configuration of the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identity, please refer to the detailed description of the examples of Figures 17 and 18. Referring to Figure 17, the base station maps the SPS configuration index to the SPS group identity through MAC CE or RRC dedicated signaling. In this example, the mapping may be a many-to-one mapping relationship, that is, multiple SPS configurations are mapped to one SPS group identity.

[0170] In one embodiment, the mapping through the RRC dedicated signaling may be that the SPS configuration includes an SPS group identity, i.e., the SPS group to which the SPS configuration belongs is identified in the SPS configuration. In another embodiment, the mapping through the RRC dedicated signaling may be that the SPS group configuration carrying the group identity includes a plurality of SPS configurations and an SPS index corresponding to the SPS configuration.

[0171] In one embodiment, sending the activation command or deactivation command to the UE further includes: downlink control information (DCI) is used to send information of the semi-persistent resource configuration index or information of the semi-persistent resource group identity; and the semi-persistent resource configuration is activated or deactivated for the semi-persistent resource configuration index or the semi-persistent resource group identity based on the activation command or deactivation command.

[0172] SPS activation or deactivation may be performed for an SPS group identity or separately for each SPS index, and similarly, CG activation or deactivation may be performed for a CG group identity or separately for each CG index.

[0173] The base station maps the SPS configuration index to the SPS group identity through MAC CE or RRC dedicated signaling. For a method of indicating the mapping through MAC CE, please refer to Figures 19 and 20.

[0174] One embodiment is shown in FIG. 19, in which the 4 bits marked in dark colors represent an SPS Group ID bitmap. The 12 bits marked in light colors represent an SPS configuration index bitmap. A bitmap is a way of representing a data structure by bits. The 4 bits marked in dark colors in FIG. 19 can represent 16 SPS group identifications. In the 12 bits marked in light colors in FIG. 19, if the value of one bit is 1, it indicates that the SPS group identification represented by the 4 bits marked in dark colors includes an SPS configuration index corresponding to that bit, and if the value of one bit is 0, it indicates that the SPS group identification represented by the 4 bits marked in dark colors does not include an SPS configuration index corresponding to that bit.

[0175] Another embodiment is shown in FIG. 20, in which the 4 bits marked in dark colors represent an SPS Group ID bitmap. The 12 bits marked in light colors represent an SPS configuration index bitmap. In the 4 bits marked in dark colors in FIG. 20, each bit can represent one SPS group identification, and the 4 bits represent a total of four SPS group identifications. For example, the first SPS group identification is represented by the first bit having a value of 1 and each of the other three bits having a value of 0, and the second SPS group identification is represented by the second bit having a value of 1 and each of the other three bits having a value of 0. Similarly, in the 12 bits marked in light colors in FIG. 20, if the value of one bit is 1, it means that the SPS group identification represented by the 4 bits marked in dark colors is the SPS group identification corresponding to that bit. indicates that the SPS group identification information represented by the 4 bits marked in a dark color does not include an SPS configuration index corresponding to that bit, and if the value of 1 bit is 0, it indicates that the SPS group identification information represented by the 4 bits marked in a dark color does not include an SPS configuration index corresponding to that bit.

[0176] In one embodiment, the downlink control information (DCI) is used to transmit the information of the semi-persistent resource configuration index or the information of the semi-persistent resource group identification information, including:

[0177] The value range of the semi-persistent resource configuration index information and the value range of the semi-persistent resource group identification information are set separately, and the semi-persistent resource configuration index information and the semi-persistent resource group identification information information are represented in the DCI by reuse.

[0178] Currently, in the activation or deactivation of the semi-persistent resource configuration, the resource identification information in the DCI can only have at most 4 bits that can represent 16 values. However, the downlink semi-persistent resource configuration index needs at least 8 values, and the uplink semi-persistent resource configuration index needs 16 values. Therefore, in the current radio resource configuration method, there is no single bit to represent the semi-persistent resource configuration group. If the activation or deactivation of the semi-persistent resource and the activation or deactivation of the semi-persistent resource group are supported simultaneously, the reuse method of the resource group identification information needs to be considered. In one embodiment, the method further includes that in the value range of the semi-persistent resource configuration index and the semi-persistent resource group identification information carried by the DCI, each A value of the first part of the value range is set to the index value of the semi-persistent resource configuration index, and each B value of the second part of the value range is set to the index value of the semi-persistent resource group identification information. A and B are positive integers. The first part and the second part do not overlap.

[0179] In one embodiment, in a given value range of DCI resource configuration indices, each of the first A values ​​is set to an index value of a semi-persistent resource configuration index, and each of the last B values ​​is set to an index value of a semi-persistent resource group identity, where A and B are positive integers. The sum of A and B is less than or equal to the number of values ​​in the given value range.

[0180] The SPS configuration index and the SPS group identity need to be represented simultaneously by 4 bits in the DCI, i.e., a total of 16 values. Therefore, the 4-bit values ​​in the DCI need to be reused in one of the following ways:

[0181] In reuse method 1, the value range of the SPS configuration index and the value range of the SPS group identification information may have different configurations. For example, in example 1, the value range of the SPS configuration index is 1 to 8, and the value range of the SPS group identification information is 9 to 16 or 13 to 16. Alternatively, in example 2, the value range of the SPS configuration index is 1 to 12, and the value range of the SPS group identification information is 13 to 16.

[0182] In Example 2 above, the predefined value range of the DCI resource configuration index is 1 to 16. A=12 and B=4 are predefined. Each of the first A values, 1 to 12, is set to the index value of the semi-persistent resource configuration index. Each of the last B values, 13 to 16, is set to the index value of the semi-persistent resource group identification information. A and B are positive integers. The sum of A and B is equal to the number of values ​​in the predefined value range, i.e., 16.

[0183] In one embodiment, the value index of the semi-persistent resource group identification information is calculated by the following method: It is constructed using one of the following:

[0184] In method 1, an index value of the semi-persistent resource group identification in the semi-persistent resource configuration information is configured as an index value of the semi-persistent resource group identification in the DCI. Alternatively, in method 2, an index value of the semi-persistent resource group identification in the semi-persistent resource configuration information is configured as a difference between an index value of the semi-persistent resource group identification in the DCI and a predetermined offset value.

[0185] Method 1 corresponds to the above-mentioned embodiment of reuse method 1. Method 2 corresponds to the following embodiment of reuse method 2. In reuse method 2, the index value of the semi-persistent resource group identity in the DCI is preset by adding the index value of the semi-persistent resource group identity to a predefined offset value.

[0186] In the reuse method 2, the value range of the SPS configuration index and the value range of the SPS group identity may be the same in the configuration. However, the SPS group identity may add a predefined offset value so that it is mapped to the group identity in the DCI. For example, the value range of the SPS configuration index is 1 to 8, the value range of the SPS group identity is 1 to 8, and the predefined offset value "+8" is configured so that the SPS group identity represents the SPS group identity in the DCI. Such a configuration of the SPS group identity may be referred to as the SPS group identity start offset.

[0187] When activation or deactivation is performed, the SPS activation or deactivation may be performed for the SPS group identification or may be performed separately for each SPS index.

[0188] The above method is also suitable for uplink (UL) SPS. That is, the above method is also suitable for CG. For example, the base station maps the CG configuration index to the CG group identity through MAC CE or RRC dedicated signaling. In this example, the mapping may be a many-to-one mapping relationship. That is, one or more CG configurations are mapped to one CG group identity.

[0189] In one embodiment, the mapping through RRC dedicated signaling may be that the CG configuration includes a CG group identity, i.e., the CG group to which the CG configuration belongs is identified in the CG configuration. In another embodiment, the mapping through RRC dedicated signaling may be that the CG group configuration carrying the group identity includes one or more CG configurations and one or more CG indices corresponding to the one or more CG configurations. Please refer to Figures 21 and 22 for how to indicate the mapping through the MAC CE.

[0190] One embodiment is shown in Figure 21, where the 4 bits marked in dark colors represent a CG group identification information (CG Group ID) bitmap, and the 12 bits marked in light colors represent a CG configuration index bitmap. As in Figure 19, the 4 bits marked in dark colors in Figure 21 can represent 16 CG group identification information. In the 12 bits marked in light colors in Figure 21, whether the value of one bit to be set is 1 or 0 indicates whether the CG group identification information represented by the 4 bits marked in dark colors includes a CG configuration index corresponding to that bit.

[0191] Another embodiment is shown in FIG. 22, where the 4 bits marked in dark color represent the CG Group ID bitmap, and the 4 bits marked in light color represent the CG Group ID bitmap. The 12 bits marked in the dark color represent the CG configuration index bitmap. As in FIG. 20, in the 4 bits marked in dark color in FIG. 22, each bit can represent one CG group identification information, and the 4 bits represent a total of 4 CG group identification information. For detailed indication method, please refer to the description of FIG. 20 and will not be repeated here.

[0192] The CG configuration index and the CG group identification information need to be represented simultaneously by 4 bits in the DCI, i.e., a total of 16 values. Therefore, the 4-bit values ​​in the DCI need to be reused in one of the following ways:

[0193] In the reuse method 3, the value range of the CG configuration index and the value range of the CG group identification information may have different configurations. For example, the value range of the CG configuration index is from 1 to 12, and the value range of the CG group identification information is from 13 to 16.

[0194] In reuse method 4, the value range of the CG configuration index and the value range of the CG group identification information may be the same in the configuration. However, the CG group identification information may be added with a predefined offset value so that it is mapped to the group identification information in the DCI. For example, the value range of the CG configuration index is 1 to 12, the value range of the CG group identification information is 1 to 4, and the predefined offset value "+4" is configured so that the CG group identification information represents the CG group identification information in the DCI. Such a configuration of the CG group identification information may be referred to as a CG group identification information start offset.

[0195] When activation or deactivation is performed, the CG activation or deactivation may be performed for the CG group identification information or may be performed separately for each CG index.

[0196] Referring to Figure 18, the base station maps the SPS configuration index to the SPS group identity through MAC CE or RRC dedicated signaling. In this example, the mapping may be a one-to-many mapping relationship, that is, one SPS configuration is mapped to one or more SPS group identities.

[0197] In one embodiment, the mapping through the RRC dedicated signaling may be that the SPS configuration includes a bitmap type SPS group identity indication, where each bit corresponds to one SPS group identity. In another embodiment, the mapping through the RRC dedicated signaling may be that the SPS group configuration carrying the group identity includes multiple SPS configurations and SPS indexes corresponding to the SPS configurations.

[0198] For the method of indicating mapping through the MAC CE, please refer to Figures 19 and 20, and it will not be repeated here.

[0199] Similarly, the SPS configuration index and the SPS group identification information need to be simultaneously represented by 4 bits in the DCI, i.e., a total of 16 values. Therefore, it is necessary to reuse the 4-bit values ​​in the DCI. For the reuse, please refer to the relevant descriptions of the reuse method 1 and reuse method 2 described above, and the description will not be repeated here.

[0200] The above method is also suitable for UL SPS. That is, the above method is also suitable for CG. For example, the base station maps the CG configuration index to the CG group identity through MAC CE or RRC dedicated signaling. The mapping may be one-to-many (i.e., one CG configuration is mapped to one or more CG group identities).

[0201] In one embodiment, the mapping through the RRC dedicated signaling may be that the CG configuration includes a bitmap type CG group identity indication, with each bit corresponding to one CG group identity. In another embodiment, the mapping through the RRC dedicated signaling may be that the CG group configuration carrying the group identity includes multiple CG configurations and CG indices corresponding to the CG configurations. For the indication method of the mapping through the MAC CE, please refer to Figures 21 and 22 and will not be repeated here.

[0202] Similarly, the CG configuration index and the CG group identification information need to be simultaneously represented by 4 bits in the DCI, i.e., a total of 16 values. Therefore, it is necessary to reuse the 4-bit values ​​in the DCI. For the reuse, please refer to the relevant explanations of the reuse method 3 and reuse method 4 described above, and the details will not be repeated here.

[0203] In one embodiment, the method further includes configuring one or more sets of semi-persistent resource configurations for each semi-persistent resource configuration index. Each set of semi-persistent resource configurations corresponds to a value range of at least one process identification information. The value range includes at least one process identification information. Alternatively, the value range includes a starting value of the process identification information and a number of processes.

[0204] In this embodiment, one or more sets of semi-persistent resource configurations are configured for each semi-persistent resource configuration index. Each semi-persistent resource configuration index corresponds to an application scenario of one or more sets of semi-persistent resources. The one or more sets of semi-persistent resource configurations respectively correspond to application scenarios of one or more sets of semi-persistent resources. Each set of semi-persistent resource configurations corresponds to a value range of at least one process identification information.

[0205] Figure 23 is a diagram illustrating the configuration of a semi-persistent scheduling group in a wireless resource configuration method according to an embodiment of the present application. As shown in Figure 23, a semi-persistent resource configuration list (SPS Config List) includes multiple semi-persistent resource configuration indexes (SPS Config indexes). As shown in Figure 23, the semi-persistent resource configuration list includes semi-persistent resource configuration index 1, semi-persistent resource configuration index 2, ..., and semi-persistent resource configuration index a. Taking semi-persistent resource configuration index 1 as an example, multiple sets of semi-persistent resource configurations configured for semi-persistent resource configuration index 1 include semi-persistent resource configuration pattern (SPS Resource Pattern) 1, semi-persistent resource configuration pattern 2, ..., and semi-persistent resource configuration pattern m.

[0206] In one embodiment, configuring a set of one or more semi-persistent resource configurations for each semi-persistent resource configuration index includes configuring a set of one or more semi-persistent resource configurations for each semi-persistent resource configuration index through RRC dedicated signaling.

[0207] In one example, the base station configures multiple sets of SPS resources for one SPS configuration index through RRC dedicated signaling. The SPS resources include at least one of the following contents: an SPS period or an SPS start offset. In one example, one SPS configuration index is configured with multiple sets of SPS resources. The first set of SPS resources is configured with a start time domain position. For other sets of SPS resources except the first set of SPS resources, the resource position of each set of SPS resources is configured as an SPS start offset relative to the first set of SPS resources.

[0208] SPS activation or deactivation is performed on an SPS configuration index. Each activation or deactivation is effective for the SPS resource corresponding to the SPS configuration index. That is, each activation or deactivation is effective for one or more sets of SPS resource configurations corresponding to the SPS configuration index.

[0209] The above method is also suitable for UL SPS. That is, the above method is also suitable for CG. In one example, the base station configures multiple sets of CG resources for one CG configuration index through RRC dedicated signaling. The CG resource includes at least one of the following contents: CG period or CG start offset.

[0210] CG activation or deactivation is performed on a CG configuration index. Each activation or deactivation is effective for the CG resources corresponding to the CG configuration index. That is, each activation or deactivation is effective for one or more sets of CG resource configurations corresponding to the CG configuration index.

[0211] In one embodiment, the method further includes configuring a start value of the process identification information and the number of processes for each semi-persistent resource configuration or each set of semi-persistent resources in each semi-persistent resource configuration. In an application scenario corresponding to each semi-persistent resource configuration or each set of semi-persistent resources in each semi-persistent resource configuration, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. The application scenario for each set of semi-persistent resources includes at least one of the following scenarios: Each set of semi-persistent resources is configured as an SPS, and the period of each semi-persistent resource configuration is a slot, a subframe, a millisecond, or a Hertz, or each set of semi-persistent resources is configured as a CG.

[0212] For a scenario where one semi-persistent resource configuration includes one or more sets of semi-persistent resources, each set of semi-persistent resource configurations has a corresponding process identification range. At least one process identification (ID) of each set of resources needs to be calculated separately. In one embodiment, the process identification range includes at least one of the following contents: a process identification start value and a number of processes. In one embodiment, the process identification range includes at least the number of processes.

[0213] In one embodiment, the process identification information corresponding to the semi-persistent resource time domain location is calculated based on a start value of the process identification information and the number of processes includes the process identification information corresponding to the semi-persistent resource location is calculated based on time domain information of a current time domain location of each set of semi-persistent resources, the number of slots in each radio frame, the number of slots in the current frame, the start value of the process identification information, a period of each semi-persistent resource configuration, and the number of processes, or the process identification information corresponding to the semi-persistent resource location is calculated based on the number of slots in each radio frame, the time domain information of a start time domain location of each semi-persistent resource configuration, a resource location number, the start value of the process identification information, a period of each semi-persistent resource configuration, and the number of processes.

[0214] In one embodiment, the current time domain location is an NR time domain location represented by at least one of the following manners: a system superframe number, a system frame number, a slot number, or a symbol number. The start time domain location of each semi-persistent resource configuration is an absolute time domain location configured through dedicated signaling, a relative time domain location offset by M time units with respect to the time of receiving the DCI activation command, or a time domain location jointly determined based on a time domain offset configured by dedicated signaling and an offset of M time units with respect to the time of receiving the DCI activation command. The time unit may be a radio frame, a subframe, a slot, or a symbol.

[0215] For example, the time domain information of the start time domain location of each semi-persistent resource configuration is indicated through at least one of the following parameters: SFN start time, slot start time, or symbol start time. The SFN start time represents the start radio frame number of the resource in the semi-persistent resource configuration, the slot start time represents the start slot number of the resource in the semi-persistent resource configuration, and the symbol start time represents the start symbol number of the resource in the semi-persistent resource configuration. The value of each of the above parameters may be determined in one of the following manners: an absolute time domain location configured through dedicated signaling, a relative time domain location offset by M time units with respect to the receiving time of the DCI activation command, or a time domain location jointly determined based on the time domain offset configured by dedicated signaling and an offset of M time units with respect to the receiving time of the DCI activation command, where M is a non-negative integer. One of the time units may be a radio frame, a subframe, a slot, or a symbol.

[0216] In the application scenario corresponding to each semi-persistent resource configuration or each set of semi-persistent resources in each semi-persistent resource configuration, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. Examples of calculating the process identification information in different application scenarios are as follows:

[0217] In the first calculation method example, for the downlink SPS, when the period of each semi-persistent resource configuration is within a slot, a hybrid automatic repeat request (HARQ) process is taken as an example. The calculation formula for the process ID of each set of downlink SPS is as follows:

[0218] HARQ Process ID = [floor(CURRENT_Slot / Periodicity)] modulo nrofHARQ-Processes + harqProcessIdOffset.

[0219] HARQ Process ID represents the HARQ process ID. floor is the rounding down operator. periodicity represents the period of the semi-persistent resource configuration. modulo is the modulo operator. nrofHARQ-Processe represents the number of HARQ processes. harqProcessIdOffsetharqProcessIdOffset represents the start value of the process identification information. CURRENT_slot is calculated using Equation 1 or Equation 2 below.

[0220] In Equation 1, CURRENT_slot = [(SFN x numberOfSlotsPerFrame) + slot number within a frame].

[0221] SFN stands for System Frame Number. numberOfSlotsPerFrame stands for the number of slots in each radio frame. number of slots in frame stands for the number of slots in the current frame.

[0222] In Equation 2, CURRENT_slot = [(SFNstart time x numberOfSlotsPerFrame + slotstart time) + N x periodicity].

[0223] numberOfSlotsPerFrame represents the number of slots in each radio frame, SFNstart time and slotstart time represent the starting radio frame number and starting slot number of the SPS resource, respectively. Periodicity represents the period of the semi-persistent resource configuration, where N is a positive integer representing the resource position number, and N>=0.

[0224] One of the above Equation 1 or Equation 2 may be selected to calculate CURRENT_slot based on different application scenarios. Equation 1 is suitable for scenarios where the service period is an integer factor of 10240 ms (e.g., one SFN period). Otherwise, the number of HARQ process IDs in different SFN periods may be different, and the values ​​of HARQ process IDs may be discontinuous across SFN periods, so that the value of CURRENT_slot cannot be calculated using Equation 1. Equation 2 is suitable for service periods of any length.

[0225] In the calculation method example 2, for the downlink SPS, when the periodicity is subframe or millisecond (ms), the HARQ process is taken as an example. The calculation formula of the process ID of each set of downlink SPS is as follows:

[0226] HARQ Process ID = [floor(CURRENT_Slot / Periodicity)] modulo nrofHARQ-Processes + harqProcessIdOffset.

[0227] HARQ Process ID represents the HARQ process ID. floor is the rounding down operator. numberOfSlotsPerSubFrame represents the number of slots in each subframe. periodicity represents the period of the semi-persistent resource configuration. modulo is the modulo operator. nrofHARQ-Processe represents the number of HARQ processes. harqProcessIdOffsetharqProcessIdOffset represents the start value of the process identification information. CURRENT_slot is calculated using Equation 1 or Equation 2 below.

[0228] In the calculation method example 3, for the uplink SPS, the HARQ process is also taken as an example. The calculation formula for the process ID of each set of CG resources is as follows:

[0229] HARQ Process ID = [floor(CURRENT_Slot / Periodicity)] modulo nrofHARQ-Processes + harqProcessIdOffset.

[0230] HARQ Process ID represents the HARQ process ID. floor is the rounding down operator. periodicity represents the period of the semi-persistent resource configuration. modulo is the modulo operator. nrofHARQ-Processe represents the number of HARQ processes. harqProcessIdOffsetharqProcessIdOffset represents the start value of the process identification information. CURRENT_slot is calculated using the following Equation 3.

[0231] In Equation 3, CURRENT_symbol = [(SFNstart time x numberOfSlotsPerFrame * numberOfSymbolsPerSlot + slotstart time * numberOfSymbolsPerSlot + Symbolstart time) + N x periodicity].

[0232] numberOfSlotsPerFrame and numberOfSymbolsPerSlot respectively represent the number of slots in each radio frame and the number of symbols in each slot. SFNstart time, slotstart time, and Symbolstart time respectively represent the start radio frame number of the CG resource, C It represents the starting slot number of the G resource and the starting symbol number of the CG resource. The periodicity represents the period of the semi-persistent resource configuration. N is a positive integer representing the resource position number, where N>=0.

[0233] In the above formula, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. The base station sends radio resource configuration information, such as the start value of the process identification information and the number of processes, to the UE through RRC dedicated signaling. The base station and the UE use the same formula and method as above to calculate the process identification information corresponding to the semi-persistent resource time domain position, so that the synchronization between the base station and the UE is achieved through the above radio resource configuration method.

[0234] 24 is a flowchart illustrating the configuration of a semi-persistent scheduling group in a radio resource configuration method applied to a UE according to an embodiment of the present application. As shown in FIG. 24, the radio resource configuration method applied to a UE according to an embodiment of the present application includes:

[0235] At S510, semi-persistent resource configuration information is received. The semi-persistent resource configuration information includes a mapping relationship between a semi-persistent resource configuration index and a semi-persistent resource group identification information.

[0236] At S520, an activation or deactivation command is received, and through the activation or deactivation command, a semi-persistent resource configuration is activated or deactivated for a semi-persistent resource group identification information.

[0237] As mentioned above, in the semi-persistent resource configuration group method, the semi-persistent resource configurations that can be activated at the same time need to be classified into one group. In S510, the UE establishes a mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identity. In S520, the activation command or deactivation command received by the UE includes information of the semi-persistent resource configuration index or the semi-persistent resource group identity, and the semi-persistent resource configuration is activated or deactivated for the semi-persistent resource group identity based on the activation command or deactivation command. In order to save overload in activating or deactivating resources, the semi-persistent resource configurations with the same activation opportunity or deactivation opportunity can be regarded as one semi-persistent resource configuration group.

[0238] In one embodiment, the semi-persistent resource configuration index includes a semi-persistent scheduling (SPS) configuration index or a configuration grant (CG) configuration index.

[0239] As mentioned above, in the embodiment of the present application, the uplink resource pre-configuration and the downlink resource pre-configuration are respectively referred to as semi-persistent resource configuration.

[0240] In one embodiment, the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identification information includes a mapping relationship between one semi-persistent resource group identification information and a plurality of semi-persistent resource configuration indexes. Each semi-persistent resource configuration corresponds to a value range of at least one process identification information. The value range includes at least one process identification information. Alternatively, the value range includes a start value of the process identification information and a number of processes.

[0241] With reference to the embodiment shown in FIG. 17, one semi-persistent resource group includes multiple semi-persistent resource configurations.

[0242] In one embodiment, the mapping relationship between the semi-persistent resource configuration index and the semi-persistent resource group identification information includes a mapping relationship between one semi-persistent resource configuration index and multiple semi-persistent resource group identification information. Each semi-persistent resource configuration corresponds to a value range of at least one process identification information. The value range includes at least one process identification information. Alternatively, the value range includes a start value of the process identification information and a number of processes.

[0243] With reference to the embodiment shown in FIG. 18, one semi-persistent resource configuration may belong to multiple different semi-persistent resource groups.

[0244] In one embodiment, receiving the semi-persistent resource configuration information includes: Semi-persistent resource configuration information is received through MAC CE or RRC dedicated signaling.

[0245] In this embodiment, through MAC CE or RRC dedicated signaling, the base station maps the SPS configuration index to the SPS group identity, or maps the CG configuration index to the CG group identity, so that the UE receives the semi-persistent resource configuration information through MAC CE or RRC dedicated signaling.

[0246] In one embodiment, receiving the activation or deactivation command further includes:

[0247] The method further includes obtaining information of a semi-persistent resource configuration index or information of a semi-persistent resource group identification information, the information of the semi-persistent resource configuration index or the information of the semi-persistent resource group identification information being carried by a DCI, and the semi-persistent resource configuration being activated or deactivated for the semi-persistent resource configuration index or the semi-persistent resource group identification information based on an activation command or a deactivation command.

[0248] SPS activation or deactivation may be performed for an SPS group identity or may be performed separately for each SPS index. Similarly, CG activation or deactivation may be performed for a CG group identity or may be performed separately for each CG index. To save overload in resource activation or deactivation, semi-persistent resource configurations with the same activation or deactivation opportunity can be considered as one semi-persistent resource configuration group.

[0249] The next-generation Node B maps the SPS configuration index to the SPS group identity through MAC CE or RRC dedicated signaling. For how to indicate the mapping through MAC CE, please refer to Figures 19 and 20.

[0250] In one embodiment, the semi-persistent resource configuration index information or the semi-persistent resource group identification information includes the semi-persistent resource configuration index information or the semi-persistent resource group identification information represented in the DCI by reusing based on a predefined value range of the semi-persistent resource configuration index information and a predefined value range of the semi-persistent resource group identification information.

[0251] Currently, in the activation or deactivation of a semi-persistent resource configuration, the resource identification information in the DCI can only have a maximum of 4 bits that can represent 16 values. However, the downlink semi-persistent resource configuration index requires at least 8 values, and the uplink semi-persistent resource configuration index requires 16 values. If simultaneous activation / deactivation of semi-persistent resources and activation / deactivation of semi-persistent resource groups is supported, then consideration must be given to how resource group identification information is reused.

[0252] In one embodiment, the method further includes, in a value range of the semi-persistent resource configuration index and the semi-persistent resource group identity carried by the DCI, obtaining A-bit values ​​of a first portion of the value range, and setting each of the A-bit values ​​to an index value of the semi-persistent resource configuration index, and obtaining B-bit values ​​of a second portion of the value range, and setting each of the B-bit values ​​to an index value of the semi-persistent resource group identity, where A and B are positive integers. The first and second portions do not overlap.

[0253] In one embodiment, in a given value range of DCI resource configuration indices, each of the first A values ​​is set to an index value of a semi-persistent resource configuration index, and each of the last B values ​​is set to an index value of a semi-persistent resource group identity, where A and B are positive integers. The sum of A and B is less than or equal to the number of values ​​in the given value range.

[0254] For example, the predetermined value range of the index of the DCI resource configuration is from 1 to 16. Let A=12 and B=4. Each of the first A values, which are from 1 to 12, is set to the index value of the semi-persistent resource configuration index. Each of the last B values, which are from 13 to 16, is set to the index value of the semi-persistent resource group identity information. A and B are positive integers. The sum of A and B is equal to the number of values ​​in the predetermined value range, i.e., 16. For a detailed indication method, please refer to the relevant description on the method applied to the base station and configured to configure the semi-persistent scheduling group according to the embodiment of the present application, and will not be repeated here.

[0255] In one embodiment, the value index of the semi-persistent resource group identity information is constructed using one of the following methods.

[0256] In the semi-persistent resource configuration information, the index value of the semi-persistent resource group identification information in the DCI is regarded as the index value of the semi-persistent resource group identification information. Alternatively, in the semi-persistent resource configuration information, the difference between the index value of the semi-persistent resource group identification information in the DCI and the predefined offset value is regarded as the index value of the semi-persistent resource group identification information.

[0257] For example, the value range of the SPS configuration index and the value range of the SPS group identity may be the same in the configuration. However, the SPS group identity may add a predefined offset value so that it is mapped to the group identity in the DCI. For example, the value range of the SPS configuration index is 1 to 8, the value range of the SPS group identity is 1 to 8, and the predefined offset value "+8" is configured so that the SPS group identity represents the SPS group identity in the DCI.

[0258] After receiving the indication method mapped through the MAC CE, the UE can analyze the index value of the semi-persistent resource configuration index and the index value of the semi-persistent resource group identity information according to a preset value range of the information of the semi-persistent resource configuration index and a preset value range of the information of the semi-persistent resource group identity information, and further, the activation or deactivation is performed based on the analyzed radio resource configuration information.

[0259] The above method is also suitable for uplink (UL) SPS. The method is also suitable for CG. For example, the base station maps the CG configuration index to the CG group identity through MAC CE or RRC dedicated signaling. For the method of indicating the mapping through MAC CE, please refer to FIG. 21 and FIG. 22. For the related method for CG configured to be applied to the UE, please refer to the related description of the method configured to be applied to the base station and to configure the semi-persistent scheduling group according to the embodiment of the present application, and will not be repeated here. In one embodiment, the semi-persistent resource configuration information further includes that each semi-persistent resource configuration index corresponds to one or more sets of semi-persistent resources. Each set of semi-persistent resource configuration corresponds to a value range of at least one process identity. The value range includes at least one process identity. Alternatively, the value range includes a start value of the process identity and the number of processes.

[0260] As shown in Figure 23, the semi-persistent resource configuration list (SPS Config List) includes multiple semi-persistent resource configuration indexes (SPS Config indexes). Taking the semi-persistent resource configuration index 1 as an example, multiple sets of semi-persistent resource configurations configured for the semi-persistent resource configuration index 1 include semi-persistent resource configuration pattern (SPS Resource Pattern) 1, semi-persistent resource configuration pattern 2, ..., and semi-persistent resource configuration pattern m.

[0261] In one embodiment, the method further comprises: RRC dedicated signaling is received, the RRC dedicated signaling carrying one or more sets of semi-persistent resource configurations corresponding to each semi-persistent resource configuration index.

[0262] In one embodiment, in the RRC dedicated signaling received by the UE, multiple sets of SPS resources are configured for one SPS configuration index. The SPS resources include at least one of the following contents: SPS periodicity or SPS start offset. SPS activation or deactivation is performed for the SPS configuration index. Each activation or deactivation is effective for the SPS resources corresponding to the SPS configuration index. The above method is also suitable for UL SPS. That is, the above method is also suitable for CG.

[0263] In one embodiment, each semi-persistent resource configuration index corresponds to an application scenario of one or more sets of semi-persistent resources. Each set of semi-persistent resource configurations corresponds to a value range of at least one process identification information. Based on a specific application scenario, the UE can use the corresponding semi-persistent resource configuration to calculate the process identification information corresponding to the semi-persistent resource time domain position.

[0264] In one embodiment, the method further comprises: In an application scenario corresponding to each semi-persistent resource configuration or each set of semi-persistent resources in each semi-persistent resource configuration, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. The application scenario for each set of semi-persistent resources includes at least one of the following scenarios: each set of semi-persistent resources is configured as an SPS, and the period of each semi-persistent resource configuration is a slot, a subframe, a millisecond, or a Hertz, or each set of semi-persistent resources is configured as a CG.

[0265] For a scenario in which a semi-persistent resource configuration includes one or more sets of semi-persistent resources, each set of the semi-persistent resource configuration has a corresponding process identification range. At least one process identification (ID) of each set of resources is calculated separately. In one embodiment, the process identification information range includes at least one of the following: a start value of the process identification information and a number of processes. In one embodiment, the process identification information range includes at least the number of processes.

[0266] In one embodiment, the process identification information corresponding to the semi-persistent resource time domain location is calculated based on a start value of the process identification information and the number of processes includes the process identification information corresponding to the semi-persistent resource location is calculated based on time domain information of a current time domain location of each set of semi-persistent resources, the number of slots in each radio frame, the number of slots in the current frame, the start value of the process identification information, a period of each semi-persistent resource configuration, and the number of processes, or the process identification information corresponding to the semi-persistent resource location is calculated based on the number of slots in each radio frame, the time domain information of a start time domain location of each semi-persistent resource configuration, a resource location number, the start value of the process identification information, a period of each semi-persistent resource configuration, and the number of processes.

[0267] In one embodiment, the current time domain location is an NR time domain location represented by at least one of the following manners: a system superframe number, a system frame number, a slot number, or a symbol number. The start time domain location of each semi-persistent resource configuration includes at least one of an absolute time domain location configured through dedicated signaling, a relative time domain location offset by M time units with respect to the time of receiving the DCI activation command, or a time domain location jointly determined based on a time domain offset configured by dedicated signaling and an offset of M time units with respect to the time of receiving the DCI activation command, where M is a non-negative integer. One of the time units may be a radio frame, a subframe, a slot, or a symbol.

[0268] In the application scenario corresponding to each semi-persistent resource configuration or each set of semi-persistent resources in each semi-persistent resource configuration, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. Corresponding formulas can be configured to calculate the process identification information in different application scenarios. For the calculation method, please refer to the calculation method example 1, calculation method example 2, and calculation method example 3 described in the method applied to the base station and configured to configure the semi-persistent scheduling group according to the embodiment of the present application, and will not be repeated here.

[0269] In the above calculation example, the process identification information corresponding to the semi-persistent resource time domain position is calculated based on the start value of the process identification information and the number of processes. The base station transmits radio resource configuration information, such as the start value of the process identification information and the number of processes, to the UE through RRC dedicated signaling. The base station and the UE use the same formula and method as above to calculate the process identification information corresponding to the semi-persistent resource time domain position, so that the synchronization between the base station and the UE is achieved through the above radio resource configuration method.

[0270] Regarding the aforementioned radio resource configuration method applied to a UE and configured to configure a semi-persistent scheduling group, please refer to the description of the radio resource configuration method applied to a base station and configured to configure a semi-persistent scheduling group according to an embodiment of the present application, and it will not be repeated here.

[0271] In another aspect, the transmission delay sensitivity of the IIoT service is taken into consideration. For example, the transmission delay sensitivity is generally less than 0.5 ms. However, currently, in the NR radio access network system, the minimum duration (or measurement period) of the radio measurement gap is 1.5 ms. Furthermore, during the measurement gap period, the UE cannot transmit or receive services in connected mode. Therefore, the transmission delay requirements of the IIoT service cannot be met using the current measurement gap. In this regard, the embodiment of the present application considers the transmission delay sensitivity of the TSC service. A radio resource configuration method is provided that solves the above problems through short measurement gap configuration.

[0272] 25 is a flowchart illustrating a short measurement gap configuration for a TSC service in a radio resource configuration method applied to a base station according to an embodiment of the present application. As shown in FIG. 25, the radio resource configuration method includes:

[0273] In S610, a designated measurement period of the measurement target cell is transmitted to the UE. The designated measurement period is configured to instruct the UE carrying the TSC service to perform radio quality measurement within the designated measurement period. The designated measurement period includes a measurement signal transmission opportunity sequence and a measurement time window.

[0274] 25, the base station notifies the UE of the measurement signal transmission opportunity sequence of the measurement target cell or the measurement time window of the measurement target cell. The UE carrying the TSC service performs radio quality measurement only during the measurement signal reception opportunity or the measurement time window.

[0275] The measurement gap is a small gap that is generated. In this interval, the base station does not perform dedicated resource scheduling for the UE. That is, the UE does not transmit or receive dedicated services, but only performs radio quality measurements. Considering time-sensitive communication services, for example, the transmission delay sensitivity of IIoT services, the transmission delay requirements of IIoT services cannot be met using current measurement gaps. According to an embodiment of the present application, the designated measurement period of the measurement target cell is configured to meet the transmission delay requirements of the time-sensitive communication services.

[0276] In one embodiment, the designated measurement period of the measurement target cell being sent to the UE includes:

[0277] The designated measurement periods of the cells to be measured are transmitted to the UE via dedicated signaling or broadcast mechanism.

[0278] In this embodiment, the base station informs the UE of the measurement signal transmission opportunity sequence of the measurement target cell or the measurement time window of the measurement target cell through dedicated signaling or broadcast mechanism.

[0279] In one embodiment, the measurement time window includes at least one of measurement interval information, measurement gap length, or measurement start offset information.

[0280] The measurement interval information refers to an interval of a measurement gap or a repetition period of a measurement gap. The measurement interval information includes that one measurement gap is composed of an interval of L time units. The time unit of the L time units includes any one of a measurement signal interval, a symbol, a slot, a subframe, a radio frame, a millisecond, or a second. L is a positive integer. The length of the measurement gap includes K time units. The time unit of the K time units includes any one of a measurement signal interval, a symbol, a slot, or a subframe. K is a positive integer. The measurement start offset information includes configuration information configured to determine a measurement start occasion.

[0281] The time window includes at least one of measurement interval information, a length of the measurement gap, or configuration information configured to determine when the measurement begins, such as measurement start offset information.

[0282] FIG. 26 is a diagram illustrating a short measurement gap configuration for a TSC service in a radio resource configuration method according to an embodiment of the present application. As shown in FIG. 26, the measurement interval information is It refers to the interval or repetition period of the measurement gap. It may be the interval for transmitting the measurement signal, for example, the interval for transmitting L measurement signals. L is a positive integer. For example, in FIG. 26, one measurement gap is set for every two measurement signals. That is, one measurement gap is set for every other measurement signal. The measurement time window may be an SS / PBCH block measurement time configuration (SMTC) window or a similar configuration. SS block stands for synchronization signal block. PBCH stands for physical broadcast channel.

[0283] Based on the aforementioned notification of the specified measurement period and the measurement behavior, the length of the measurement gap can be configured to be relatively short. For example, the measurement is performed only upon measurement signal reception. Furthermore, the measurement gap may be configured based on the interval of the measurement signal. For example, in one embodiment, one measurement gap occurs at the interval of L measurement signals. The length of the measurement gap is based on the UE implementation or a predefined length. For example, the length of the measurement gap is a+b+c duration, where a indicates the duration of the measurement gap before the measurement signal is transmitted, b indicates the transmission duration of the measurement signal, and c indicates the duration of the measurement gap after the measurement signal is completely transmitted. a, b, c, and L may be positive integers. In another embodiment, the configuration may be performed based on the NR time unit. For example, the NR time unit may be the number of symbols, the number of slots, the number of subframes, and the number of radio frames. The starting position of the measurement gap may be determined based on the parameter configuration or may be predefined by the standard. The specific parameter configuration may include, for example, starting from some offset after the measurement gap configuration is received or starting from a predefined SFN.

[0284] In one embodiment, the measurement signal transmission opportunity sequence includes at least one of a transmission time domain position of the measurement signal, a transmission interval, or a transmission duration of the measurement signal.

[0285] The measurement signal transmission opportunity sequence is indicated by a small vertical line in Fig. 26. The UE may select one opportunity from the measurement signal transmission opportunity sequence to perform radio quality measurement.

[0286] The measurement signal includes a downlink signal configured to measure a reference signal received power (RSRP) of a cell and includes at least one of a reference signal (RS), a narrowband reference signal (NBS), a channel state information reference signal (CSI-RS), or a SS reference signal.

[0287] In one example, when measurement information, for example, measurement information including a specified measurement period, is transmitted through dedicated signaling, the UE needs to report UE-related capabilities. The base station can configure the related measurement information only for UEs that support the UE-related capabilities. The UE-related capabilities can be one of the following information: an indication of short measurement gap support capability, an indication of TSC service support capability, or an indication of measurement signal transmission opportunity sequence reception capability.

[0288] In one embodiment, the measurement target cells include a measurement target cell and / or a measurement neighbor cell set, the measurement target cells are configured to carry TSC services, and the clock information meets nanosecond (ns) level synchronization.

[0289] As shown in Figure 26, the measurement target cells include a serving cell and some neighbor cells that support the TSC service. The information of the measurement target cells may be explicitly indicated by the base station.

[0290] FIG. 27 illustrates a radio resource configuration method applied to a UE according to an embodiment of the present application. 27 is a flowchart illustrating a short measurement gap configuration for a TSC service. As shown in FIG. 27, a radio resource configuration method includes:

[0291] At S710, information regarding a designated measurement period of a measurement target cell is received. The designated measurement period includes a measurement signal transmission opportunity sequence and a measurement time window.

[0292] At S720, radio quality measurements are performed within a specified measurement period. Referring to Figure 26, the base station informs the UE of the measurement signal transmission opportunity sequence of the measurement target cell or the measurement time window of the measurement target cell. The UE carrying the TSC service performs radio quality measurement only in the measurement signal reception opportunity or the measurement time window. According to an embodiment of the present application, the designated measurement period of the measurement target cell is configured to meet the transmission delay requirement of the time-sensitive communication service (e.g., IIoT service).

[0293] In one embodiment, receiving the information of the designated measurement period of the measurement target cell includes:

[0294] The designated measurement periods of the cells to be measured are received through dedicated signaling or a broadcast mechanism.

[0295] In this embodiment, the base station informs the UE of the measurement signal transmission opportunity sequence of the measurement target cell or the measurement time window of the measurement target cell through a dedicated signaling or broadcasting mechanism. Thus, the UE receives the information of the designated measurement period of the measurement target cell through the dedicated signaling or broadcasting mechanism.

[0296] In one embodiment, the measurement time window includes at least one of measurement interval information, a length of the measurement gap, or a measurement start offset information. The measurement interval information refers to an interval of the measurement gap or a repetition period of the measurement gap.

The time unit of the L time units includes any one of a measurement signal interval, a symbol, a slot, a subframe, a radio frame, a millisecond, or a second. L is a positive integer. The length of the measurement gap includes K time units. The time unit of the K time units includes any one of a measurement signal interval, a symbol, a slot, or a subframe.

[0297] The measurement start offset information includes configuration information configured to determine the measurement start occasion.

[0298] The time window includes at least one of measurement interval information, a length of the measurement gap, or configuration information configured to determine when the measurement begins, such as measurement start offset information.

[0299] As shown in Figure 26, the measurement interval information refers to the interval of the measurement gap or the repetition period of the measurement gap. It may be in units of the interval of transmitting the measurement signal, for example, the interval of transmitting L measurement signals, where L is a positive integer. The measurement time window may be an SMTC window or a similar configuration.

[0300] For a UE based on the aforementioned notification of a specified measurement period and measurement behavior, the length of the measurement gap can be configured to be relatively short. For example, measurements are performed only upon measurement signal reception. Furthermore, the measurement gap may be configured based on the interval of the measurement signal. For example, in one embodiment, one measurement gap occurs at the interval of L measurement signals. The length of the measurement gap is based on the UE implementation or a predefined length. For example, the measurement gap may be The length of the measurement gap is a+b+c duration, where a indicates the duration of the measurement gap before the measurement signal is transmitted, b indicates the transmission duration of the measurement signal, and c indicates the duration of the measurement gap after the measurement signal is completely transmitted. a, b, c, and L may be positive integers. In another embodiment, the configuration may be performed based on an NR time unit. For example, the NR time unit may be a number of symbols, a number of slots, a number of subframes, and a number of radio frames. The starting position of the measurement gap may be determined based on a parameter configuration or may be predefined by a standard. A particular parameter configuration may include, for example, starting from some offset after the measurement gap configuration is received or starting from a predefined SFN.

[0301] In one embodiment, the measurement signal transmission opportunity sequence includes at least one of a transmission time domain position of the measurement signal, a transmission interval, or a transmission duration of the measurement signal.

[0304] In one example, when measurement information, for example, measurement information including a specified measurement period, is transmitted through dedicated signaling, the UE needs to report UE-related capabilities. The base station can configure the related measurement information only for UEs that support the UE-related capabilities. The UE-related capabilities can be one of the following information: an indication of short measurement gap support capability, an indication of TSC service support capability, or an indication of measurement signal transmission opportunity sequence reception capability.

[0305] In one embodiment, the measurement target cells include a measurement target cell and / or a measurement neighbor cell set, the measurement target cells are configured to carry TSC services, and the clock information satisfies ns level synchronization.

[0306] As shown in Figure 26, the measurement target cells include a serving cell and some neighbor cells that support the TSC service. The information of the measurement target cells may be explicitly indicated by the base station.
