[0259] The NTN is an important technology introduced by 5G, which provides wireless resources through satellites (or unmanned aerial vehicles) instead of ground base stations. Depending on the way the satellite processes the signal, it can be divided into a transparent mode and a regenerative mode. In the transparent mode, the NTN ground station sends the gNB signal to the satellite, and the satellite converts the signal to the satellite frequency band and then sends it to the UE through the satellite frequency band. Except for frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, similar to a repeater. In the regenerative mode, the NTN ground station sends the gNB signal to the satellite, which first decodes the signal and then re-encodes and modulates it (this process is regeneration) and sends the regenerated signal through the satellite frequency band.

[0260] In the NTN network architecture, even if the UE does not move on the ground, the UE needs to perform handover due to the movement of the satellite. Therefore, for satellites in non-geostationary orbits, they move at high speed relative to fixed positions on the earth, and stationary and mobile UEs perform frequent handovers in this scenario.

[0261] In the process of UE handover, the gNB sends the related parameters determined by the target base station to the UE through the radio resource control (RRC) reconfiguration message. For NGSO (Non-Geostationary Orbit), all UEs need to perform frequent handovers, which will increase the signaling overhead in the handover process. In order to reduce the signaling overhead in the handover process, group handover can be used, for example, the gNB can send a handover indication to a group of UEs, thereby reducing the signaling overhead.

[0262] The embodiments of the present disclosure can be applied to any communication scenario, such as 4G, 5G, 6G, future communication systems, vehicle-to-everything (V2X), and improved versions thereof, without specific limitation here.

[0308] In some embodiments, the terms “certain”, “preseted”, “preset”, “set”, “indicated”, “certain”, “arbitrary”, “first”, and the like can be replaced with each other, and “certain A”, “preset A”, “preset A”, “set A”, “indicated A”, “certain A”, “arbitrary A”, “first A” can be interpreted as A specified in advance in a protocol or the like, A obtained by setting, configuration, or indication, or A specific, certain, arbitrary, or first, but are not limited thereto.

[0309] In some embodiments, the second group information is used for the UE to determine the group.

[0310] In some embodiments, the second group information is used for the UE to monitor the physical downlink control channel, or the second group information is used for the UE to monitor the physical downlink control channel.

[0320] Optionally, monitoring PDCCH can be a process of blind detection of PDCCH.

[0321] Optionally, PDCCH is scrambled based on group identifier, and UE blind detects PDCCH with the group identifier (e.g., first group identifier) configured by the network (e.g., access network device or core network device).

[0322] Optionally, the scrambling based on the group identifier refers to assigning different scrambling sequences or scrambling parameters to different groups according to the group identifier (or grouping information, for example, the second grouping information). In the transmission process of the PDCCH, the sending end will select the corresponding scrambling sequence or parameter according to the group identifier to which the PDCCH belongs to scramble the control information. When the receiving end receives the scrambled PDCCH, it will perform descrambling according to the known group identifier and scrambling rule, so as to recover the original control information.

[0323] Optionally, based on the blind detection technology, the PDCCH is monitored by detecting and identifying the signal from the received signal data itself. For example, the UE attempts to decode the PDCCH candidate set that may carry the downlink control information according to the network configuration and its own state within a specific time window.

[0324] Optionally, in order to receive the control information in the PDCCH, the UE attempts to decode all PDCCH candidates according to different radio network temporary identifier (RNTI) types in the predetermined search space (Search Space).

[0325] Optionally, the UE matches the group identifier configured by the network with the group identifier of the system message, and if the matching is successful, for example, the two group identifiers are the same, it is determined that the configuration of the system message is for the matched UE group.

[0326] In some embodiments, the first group identifier name is not limited, which is, for example, "monitoring identifier", "monitoring indication identifier", etc.

[0327] In some embodiments, the second group identifier name is not limited, which is, for example, "receiving identifier", "system information identifier", etc.

[0328] In some embodiments, the third group identifier name is not limited, which is, for example, "grouping indication identifier", "grouping identifier", etc.

[0329] Optionally, the terminal obtains the information corresponding to the UE group in the system message according to the second group identifier.

[0330] Optionally, if the second grouping information is used for "UE determining grouping", for example, the second grouping information includes the third group identifier.

[0331] Optionally, if the second grouping information is used for "receiving system message", the second grouping information includes the second group identifier.

[0332] Optionally, if the second grouping information is used for "UE monitoring the physical downlink control channel", the second grouping information includes the first group identifier.

[0333] Optionally, if the second grouping information is used for both "UE grouping determination" and "indication of PDCCH monitoring", the second grouping information comprises at least one group identifier.

[0428] FIG. 2E is an interaction diagram of a terminal grouping method according to an embodiment of the present disclosure. As shown in FIG. 2E, the embodiments of the present disclosure relate to a terminal grouping method, and the above method includes:

[0429] Step S2501: The access network device 102 removes the UE from the group.

[0430] In some embodiments, the access network device 102 can remove the UE from the group based on related information of the UE, for example, at least one of location information of the UE, a measurement report reported by the UE, traffic demand of the UE, and discontinuous reception (DRX) configuration information of the UE.

[0431] Step S2502: The access network device 102 sends first removal information to the terminal 101.

[0434] In some embodiments, if the first removal information comprises indication information of the group in which the UE is removed, the indication information is used to indicate or declare the group in which the UE is removed.

[0435] In some embodiments, if the first removal information comprises second group information of the group in which the UE is removed, the first removal information corresponds to the second group information when the UE determines the group.

[0436] In some embodiments, the first removal information is used to “indicate removal of the UE from the group”.

[0437] In some embodiments, the name of the first removal information is not limited, for example, “removal group information”, “disengagement group information”, etc.

[0438] In some embodiments, the access network device 102 sends the first removal information to the terminal 101 through broadcasting or groupcasting.

[0439] In some embodiments, the first removal information is used to determine whether the UE is removed from the group, and if the UE is removed from the group, the specific group information of the removed group, etc., thereby synchronizing the situation of the UE being removed from the group to the corresponding UE, so that the UE can no longer perform group member management and other operations according to the group information after knowing the removed group.

[0440] Step S2503: The terminal 101 determines the removed group.

[0441] In some embodiments, the terminal 101 determines the removed group according to the first removal information, for example, reads the first removal information to determine the removed group.

For example, step S2501 can be implemented as an independent embodiment, step S2502 can be implemented as an independent embodiment, and steps S2502+S2503 can be implemented as an independent embodiment, but are not limited thereto.

[0443] In some embodiments, steps S2501 and S2502 can be exchanged in order or performed simultaneously.

[0444] In some embodiments, steps S2501, S2502, S2503 of FIG. 2E are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0445] In some embodiments, other optional implementations can be described before or after the description of FIG. 2E.

[0446] FIG. 2F is an interaction diagram of a terminal grouping method according to an embodiment of the present disclosure. As shown in FIG. 2F, the embodiment of the present disclosure relates to a terminal grouping method, and the method comprises:

[0447] In step S2601, the access network device 102 sends first switching information to the terminal 101.

[0448] In some embodiments, the terminal 101 receives the first switching information.

[0449] In some embodiments, the first switching information is used for “indicating group members to perform group switching” or “indicating group members to perform cell switching”.

[0450] In some embodiments, the first switching information is used for “indicating UE to perform group switching” or “indicating UE to perform cell switching”.

[0451] In some embodiments, the name of the first switching information is not limited, which is, for example, “group switching information”, “group switching information”, etc.

[0452] In some embodiments, the group member is at least one of all UEs in the group to which the UE belongs or part of the UEs in the group to which the UE belongs.

[0453] In some embodiments, the access network device 102 sends the first switching information to the terminal 101 by broadcasting or groupcasting.

[0454] Optionally, the first switching information includes group information or group identifier, UE ID, common configuration of UE grouping, etc.

[0455] Optionally, if the UE receiving the first switching information matches the group information or group identifier, UE ID, etc. carried in the first switching information, the UE performs the switching operation.

[0456] Optionally, the first switching information carries at least one of the common configuration of the target cell for the UEs in the group or the group identifier corresponding to the UE that needs to switch the cell.

[0457] Optionally, the system message (e.g., the first handover information) provides the common configuration of the target cell for the UEs in this group. The UE determines the parameter configuration of the target cell based on the group identifier carried in the system message, and then performs handover based on the parameter configuration.

[0458] In some embodiments, group handover of group members can be achieved through the first handover information, without having to send a handover instruction to each UE of the group member separately, which reduces the signaling overhead of the handover scenario, and improves the handover efficiency based on group handover.

[0459] In step S2602, terminal 101 performs cell handover.

[0460] In some embodiments, terminal 101 determines a handover group based on first handover information, for example, by reading the first handover information to determine the handover group.

[0461] Optionally, the first handover information provides the common configuration of the target cell for the UEs in this UE group. The UE determines the parameter configuration of the target cell based on the group identifier, and at the same time, the UE switches to the target cell based on the parameter configuration. Alternatively, the UE determines the cell to be handed over from the target cells based on network status, parameter configuration, etc., and the UE switches to the cell to be handed over based on the parameter configuration.

[0462] In some embodiments, when the terminal 101 performs cell handover, it performs processes such as signal measurement, determining handover decisions, and executing handover.

[0463] The communication method involved in the embodiments of this disclosure may include at least one of steps S2601 and S2602 of FIG2F. For example, step S2601 may be implemented as a separate embodiment, and step S2602 may be implemented as a separate embodiment, but is not limited thereto.

[0466] In step S2701, the access network device 102 sends RRM measurement indication information to the terminal 101.

[0467] In some embodiments, terminal 101 receives RRM measurement indication information.

[0468] In some embodiments, the RRM measurement indication information is used to "instruct at least one UE in the packet of the UE selected by the access network device 102 to perform an RRM measurement".

[0469] Optionally, the RRM measurement result of the at least one UE represents the RRM measurement results of all UEs in the group to which the UE belongs.

[0470] In some embodiments, the RRM measurement indication information is used to "indicate at least one UE in the UE group to perform RRM measurement", such as carrying one or more UE identities to perform RRM measurement, and the UE receiving the RRM measurement indication information needs to perform RRM measurement if its identity matches the carried UE identity.

[0471] In some embodiments, the name of the RRM measurement indication information is not limited, which is, for example, "wireless resource management measurement information", "RRM information", etc.

[0472] In some embodiments, the access network device 102 sends the RRM measurement indication information to the terminal 101 in a broadcast or multicast manner.

[0473] In some embodiments, the UEs in the UE group have greater relevance or similarity, and at least one UE in the group to which the UE belongs can be selected to perform RRM measurement, and the RRM measurement results of the at least one UE can obtain the RRM measurement results of all UEs in the group to which the UE belongs, without each UE performing RRM measurement and reporting RRM measurement report, thereby reducing the number of UEs performing RRM measurement, reducing UE power consumption and signaling overhead caused by RRM measurement.

[0474] Step S2702, the terminal 101 performs RRM measurement.

[0475] In some embodiments, the UE receives the broadcast or multicast RRM measurement indication information, and if the group information, group identity or UE ID carried in the RRM measurement indication information matches the group information, group identity or UE ID of the group to which the UE belongs, it is determined that the RRM measurement indication information indicates the UE to perform RRM measurement, and the UE performs RRM measurement.

[0476] In some embodiments, the terminal 101 performs RRM measurement in the following process:

[0477] Initialization and configuration:

[0478] The terminal 101 is powered on and connected to the network.

[0479] The network base station sends the terminal 101 RRM-related configuration information, including frequency, bandwidth, power control parameters, etc.

[0480] Signal measurement:

[0481] The terminal 101 periodically measures the received signal strength (such as received signal strength indication), signal-to-noise ratio, channel quality indication, etc.

[0482] Terminal 101 can also measure the signal strength of neighboring base stations for cell selection and handover.

[0483] Reporting and Feedback:

[0484] Terminal 101 reports the measurement results to the network base station. The frequency and content of the report can vary depending on network configuration and current wireless environment.

[0485] The base station allocates and adjusts resources based on the terminal's report and other network information.

[0486] Resource Allocation:

[0487] The base station dynamically allocates wireless resources (such as frequency, time slot, power, etc.) to terminal 101 based on its report and network conditions.

[0488] Terminal 101 receives resource allocation instructions from the base station and adjusts its working parameters accordingly.

[0489] Power Control:

[0490] Terminal 101 adjusts the transmission power based on the base station's instructions and its own measurement results to ensure communication quality and reduce interference.

[0491] Power control can be open-loop (based on pre-set rules) or closed-loop (based on real-time feedback).

[0492] Handover Management:

[0493] When terminal 101 moves to a different cell or signal quality decreases, terminal 101 triggers the handover process.

[0494] Terminal 101 measures the signal quality of neighboring cells and reports to the current base station.

[0495] The base station decides whether to perform handover and informs the terminal device to execute handover.

[0496] Interference Management:

[0497] Terminal 101 and the base station work together to detect and manage interference sources.

[0498] Terminal 101 may adjust the frequency, bandwidth or other parameters to reduce interference.

[0499] Load Balancing:

[0500] The base station and terminal 101 work together to ensure network load balancing and avoid overloading some cells.

[0501] Terminal 101 may be instructed to switch to a cell with lighter load.

[0502] Optimization and adjustment:

[0503] The terminal 101 and the base station continuously monitor the network performance and make optimization and adjustment.

[0504] The terminal 101 can receive new configuration parameters to adapt to the changing network environment.

[0505] The communication method related to the embodiments of the present disclosure can include at least one of step S2701 and step S2702 of FIG. 2G.
