[0238] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0239] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 .

[0240] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an IoT device, a

[0241] The present invention relates to at least one of a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

The access network device may include at least one of an evolved Node B (eNB), a next generation evolved Node B (ng-eNB), a next generation Node B (gNB), a Node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a baseband unit (BBU), a mobile switching center, a base station in a 6G communication system, an open RAN, a cloud RAN, a base station in other communication systems, and an access node in a Wi-Fi system, but is not limited thereto.

[0243] In some embodiments, the access network device can be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), where the CU can also be called a control unit (control unit). The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0244] In some embodiments, the network device 102 may also be a core network device.

[0245] In some embodiments, the core network device can be a single device, including multiple web pages, etc., or multiple devices or a group of devices. The network element can be virtual or physical. The core network, for example, includes at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC).

[0246] In some embodiments, the technical solution of the present disclosure may be applicable to the OpenRAN architecture. In this case, the embodiments of the present disclosure involve

[0247] The interfaces between or within access network devices can be transformed into OpenRAN internal interfaces, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0248] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between network devices or within network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0249] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0250] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0251] In the 5G New Radio (NR) New Radio Access Technology (New RAT) system, the Multicast Broadcast Service (MBS) can be marked with the following "MBS service identifier":

[0252] Temporary Mobile Group Identity (TMGI)

[0253] MBS Session ID

[0254] MBS QoS flow ID

[0255] In some embodiments, the MBS service transmission modes include the following two modes:

[0256] Transmission mode 1 (multicast transmission): The terminal enters the Radio Resource Control (RRC) connected state to receive the MBS transmission configuration information, so that it can receive the MBS. The network side sends the MBS service reception configuration information to the terminal through terminal-specific signaling.

[0257] Transmission Mode 2 (Broadcast Transmission): The terminal can receive MBS transmission configuration information and receive MBS in the IDLE state, the INACTIVE state, or the CONNECTED state. The network side sends the MBS service reception configuration information to the terminal through system information (e.g., System Information Block (SIB)) and MBS Control Channel (MCCH).

[0258] In some embodiments, the MBS service scheduling methods include the following two methods:

[0259] (1) Dynamic scheduling: MBS data is sent via the physical downlink shared channel (PDSCH) physical resources dynamically scheduled by the physical downlink control channel (PDCCH) using a group identifier (e.g., Group-Radio Network Temporary Identity (G-RNTI)).

[0260] (2) Semi-persistent scheduling: MBS data is sent by configuring periodically allocated PDSCH physical resources, which are activated and deactivated via PDCCH instructions. The PDCCH can be marked with a semi-persistent group identifier (e.g., Group-Configured Scheduling-Radio Network Temporary Identity (G-CS-RNTI)).

[0261] In some embodiments, the ability of a terminal to simultaneously receive one or more MBS services (i.e., PDSCHs of MBS G-RNTIs) and unicast services (i.e., PDSCHs of unicast C-RNTIs) may vary depending on the processing capabilities of different terminals. The terminal reports its processing capabilities to the network through capability reporting.

[0262] Optionally, for cells that are sending MBS broadcast services, the network provides "MBS frequency band configuration" (e.g., common frequency resource (CFR)-Configuration (Config) MCCH-Multicast Traffic Channel (MTCH)-r17) and MBS control signaling transmission resource configuration (e.g., mcch-Config-r17) through system information SIB20. The terminal receives the MCCH configuration signaling to obtain the specific MBS broadcast service transmission configuration information (e.g., MBS Broadcast Configuration (Broadcast Configuration)-r17).

[0263] Optionally, for a cell that does not send MBS broadcast services but its neighboring cells are sending MBS broadcast services, the network side provides "MBS continuity reception auxiliary information" including the frequency of sending MBS and MBS broadcast service information through system information SIB21.

[0264] In some embodiments, while a terminal is receiving a single-wavelength service on network A, it may also be receiving an MBS on network B. Since the terminal's processing capabilities are shared for both "receiving a single-wavelength service" and "receiving MBS," to avoid helping network A use the terminal's capabilities for "receiving MBS," the terminal may report the following information to the network:

[0265] MBS receiving frequency information (frequency)

[0266] MBS receiving bandwidth information (bandwidth)

[0267] MBS receives sub-carrier spacing information (SCS)

[0268] However, when a terminal reports its MBS reception capabilities to network A for network B, it may be receiving an MBS or preparing to receive it. The MBS service reception configuration information obtained by the terminal at this time is different (e.g., SIB20 / SIB21 / MCCH). Based on this MBS reception configuration information, the capabilities reported by the terminal to the network may be interpreted differently. Therefore, how to ensure that the terminal and the network have consistent understandings of the terminal's capabilities for "MBS reception" to avoid conflicts when the network uses terminal capabilities is a problem that needs to be solved.

[0269] FIG2 is an interactive diagram of a reporting method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a reporting method, which includes:

[0270] Step S2101 , the network device 102 sends second information to the terminal 101 .

[0271] In some embodiments, the second information is used to indicate that the terminal is allowed to report the first capability.

[0281] In some embodiments, the first capability is for sharing between different networks.

[0282] In some embodiments, the first capability may be a capability shared by the terminal between different networks.

[0283] For example, when network B receives MBS, the terminal can report to network A the terminal capabilities shared when network B and network A work simultaneously.

[0285] MBS receiving frequency information;

[0286] MBS receives bandwidth information;

[0287] The MBS receives subcarrier spacing information.

[0295] In some embodiments, the reference frequency point position for receiving the MBS may be the absolute frequency point (absoluteFrequencyPoint) of a reference resource block (eg, Common RB 0).

[0296] In some embodiments, the center frequency position of receiving MBS may be the center frequency position of the CFR area; the starting frequency position of receiving MBS may be the starting frequency position of the CFR area; and the ending frequency position of receiving MBS may be the ending frequency position of the CFR area.

[0297] Optionally, the CFR region may be a frequency region configured with “cfr-ConfigMCCH-MTCH” or “cfr-ConfigMCCH-MTCH-RedCap”.

[0298] In some embodiments, the frequency corresponding to the synchronization signal and physical broadcast channel PBCH block SSB of the cell receiving the MBS may be the frequency of the CD-SSB of the initial bandwidth part (Bandwidth Part, BWP) of the MBS cell.

[0299] In some embodiments, the MBS receiving bandwidth information may include at least one of the following:

[0300] Number of resource blocks;

[0301] Frequency bandwidth range.

[0302] In some embodiments, the number of resource blocks may be the number of radio resource blocks (RBs).

[0303] In some embodiments, the unit of the frequency bandwidth range may be kilohertz (kHz) or megahertz (MHz), which is not limited in the present disclosure.

[0304] In some embodiments, the specific information included in the first capability may be determined based on protocol agreements. For example, based on protocol agreements, the first capability may be determined to include MBS reception frequency information. Alternatively, based on protocol agreements, the first capability may be determined to include MBS reception frequency information, MBS reception bandwidth information, and MBS reception subcarrier spacing information. This disclosure does not specifically limit this.

[0309] Step S2102: Terminal 101 sends first information.

[0310] In some embodiments, the first information is used to report a first capability used by the terminal.

[0311] In some embodiments, the first information may also be referred to as capability reporting information, or terminal capability information, which is not specifically limited in this disclosure.

[0312] In some embodiments, when it is determined that the network device configuration allows reporting of the first capability used by the terminal, the terminal may determine, according to a protocol agreement, the specific information included in the first capability reported by the terminal.

[0313] For example, according to the protocol, the first capability reported by the terminal may include MBS reception frequency information. Alternatively, according to the protocol, the first capability reported by the terminal may include MBS reception frequency information, MBS reception bandwidth information, and MBS reception subcarrier spacing information. This disclosure does not specifically limit this.

[0314] In some embodiments, the network device 102 receives the first information sent by the terminal 101 .

[0315] In some embodiments, the terminal may also autonomously send the first information to report the first capability via the first information. In this case, step S2101 may be omitted. In other words, the terminal may autonomously report the first capability without executing step S2101. For example, the terminal may not receive the second information sent by the network device, or the network may not send the second information to the terminal, or the network may not instruct the terminal to report the first capability, or the terminal may not receive the network's instruction to report the first capability. The terminal may still autonomously decide to report the first capability.

[0316] In some embodiments, the terminal autonomously sends the first information when the first condition is met. In this case, step S2101 can be omitted. In other words, the terminal can autonomously send the first information when the first condition is met without performing step S2101. For example, the terminal may not receive the second information sent by the network device, or the network may not send the second information to the terminal, or the network may not instruct the terminal to report the first capability, or the terminal may not receive the network's instruction to report the first capability. The terminal may still autonomously decide to send the first information to report the first capability when the first condition is met.

[0317] In some embodiments, the terminal sends the first information when receiving the second information and the first condition is met.

[0318] The first condition may include at least one of the following:

[0319] Prepare to receive MBS;

[0320] Interested in receiving MBS;

[0321] Receiving MBS.

[0322] In some embodiments, the terminal is ready to receive the MBS service, which may mean that the terminal is preparing to receive the MBS service but has not yet received it.

[0323] In some embodiments, the terminal being interested in receiving the MBS may mean that the terminal is interested in the MBS service and desires to receive the MBS service of interest.

[0324] In some embodiments, the terminal is receiving the MBS service, which may mean that the terminal is receiving the MBS service according to network configuration.

[0325] In some embodiments, the reporting method of the first capability may include at least one of the following:

[0326] A first reporting mode, wherein the first reporting mode is used to report MBS reception frequency information;

[0327] The second reporting method is used to report MBS reception frequency information and at least one of MBS reception bandwidth information and MBS reception subcarrier spacing information.

[0328] In some embodiments, the first reporting method may be that the terminal only reports the MBS reception frequency information.

[0329] In some embodiments, the first reporting method may be that the terminal reports the MBS reception frequency information, but does not report the MBS reception bandwidth information and the MBS reception subcarrier spacing information.

[0330] In some embodiments, the second reporting method may be for the terminal to report the MBS reception frequency information and the MBS reception bandwidth information; or, to report the MBS reception frequency information and the MBS reception subcarrier spacing information; or, to report the MBS reception frequency information and the MBS reception bandwidth information and the MBS reception subcarrier spacing information.

[0331] In some embodiments, the terminal may determine the reporting method of the first capability according to the protocol agreement, for example, determining the reporting method of the first capability as the first reporting method according to the protocol agreement; or determining the reporting method of the first capability as the second reporting method according to the protocol agreement.

[0332] In some embodiments, if the terminal determines that the MBS continuity reception assistance information has been received, the terminal sends first information, where the first information is used to report the MBS reception frequency information.

[0333] In some embodiments, according to a protocol agreement, the terminal may report the first capability in a first reporting manner when receiving the MBS continuity reception assistance information.

[0334] In some embodiments, the MBS continuity reception assistance information may be SIB21 information, or may be other signaling that can carry the MBS continuity reception assistance information, which is not limited in the present disclosure.

[0335] In some embodiments, if the reporting method of the first capability is the first reporting method, where the first reporting method is used to report MBS reception frequency information, the MBS reception frequency information may be frequency information of a cell receiving the MBS.

[0336] In some embodiments, when the reporting mode of the first capability is the first reporting mode, the terminal only reports the frequency information of the cell receiving the MBS.

[0337] In some embodiments, when the reporting mode of the first capability is the first reporting mode, the terminal reports the cell frequency information for receiving the MBS, but does not report the MBS reception bandwidth information and the MBS reception subcarrier spacing information.

[0338] In some embodiments, the frequency information of the cell receiving the MBS service may be the receiving frequency of the cell-defining synchronization signal block (CD-SSB) of the cell receiving the MBS service.

[0339] In some embodiments, the terminal determines that it has received MBS frequency band configuration information and sends first information, wherein the first information is used to report MBS reception frequency information and at least one of MBS reception bandwidth information and MBS reception subcarrier spacing information.

[0340] In some embodiments, according to a protocol agreement, upon receiving the MBS frequency band configuration information, the terminal may report the first capability in the second reporting manner.

[0341] In some embodiments, the MBS frequency band configuration may be common frequency resource (CFR) information, or other information that can carry the MBS frequency band configuration, which is not limited in the present disclosure.

[0342] In some embodiments, the reporting method of the first capability is the second reporting method, where the second reporting method is used to report MBS reception frequency information and report at least one of MBS reception bandwidth information and MBS reception subcarrier spacing information, and the MBS reception frequency information is at least one of the following:

[0343] Reference frequency location for receiving MBS;

[0344] The center frequency position of MBS receiving;

[0345] The starting frequency position for receiving MBS;

[0346] The end frequency position of MBS reception;

[0347] The frequency corresponding to the synchronization signal and physical broadcast channel (PBCH) block (SSB) of the cell receiving MBS.

[0348] In some embodiments, if the reporting method of the first capability is the second reporting method, the MBS receiving frequency information reported by the second reporting method can be the reference frequency position for receiving the MBS; the center frequency position for receiving the MBS; the starting frequency position for receiving the MBS; the ending frequency position for receiving the MBS; and at least one of the frequencies corresponding to the synchronization signal and physical broadcast channel PBCH block SSB of the cell receiving the MBS.

[0349] In some embodiments, the MBS reception bandwidth information reported based on the second reporting method may include at least one of the following: the number of resource blocks; and a frequency bandwidth range.

[0350] In some embodiments, the first information is used to report MBS reception frequency information, the number of resource blocks, and MBS reception subcarrier spacing information.

[0351] In some embodiments, when the first capability is reported in the second reporting mode and the MBS reception bandwidth information is the number of resource blocks, the terminal needs to report the MBS reception subcarrier spacing information. Thus, the first information is used to report the MBS reception frequency information, the number of resource blocks, and the MBS reception subcarrier spacing information.

[0352] In some embodiments, the first information is used to report at least one MBS reception frequency point information and at least one MBS reception bandwidth information.

[0353] In some embodiments, when the reporting mode of the first capability is the second reporting mode, the terminal may report one MBS reception frequency point information and one or more MBS reception bandwidth information.

[0354] For example, for cell 1, the cell provides two MBS reception CFR configurations (e.g., cfr-ConfigMCCH-MTCH and cfr-ConfigMCCH-MTCH-RedCap). The terminal can receive MBS services simultaneously or switch between the two CFRs to receive MBS services. The MBS reception frequency information of the two MBS reception CFR configurations can be the same, but the MBS reception bandwidth information is different. In this case, the terminal reports one MBS reception frequency information and the corresponding two MBS reception bandwidth information.

[0355] In some embodiments, the first information is used to report at least one MBS reception frequency information and MBS reception bandwidth information corresponding to each MBS reception frequency information.

[0356] In some embodiments, when the reporting mode of the first capability is the second reporting mode, the terminal may report at least one pair of MBS reception frequency information and MBS reception bandwidth information.

[0357] For example, for cell 1, the cell provides two MBS reception CFR configurations (e.g., cfr-ConfigMCCH-MTCH and cfr-ConfigMCCH-MTCH-RedCap). The terminal can receive MBS services simultaneously or switch between the two CFRs to receive MBS services. The MBS reception frequency information and MBS reception bandwidth information of the two MBS reception CFR configurations can be different. Therefore, the terminal reports two pairs of MBS reception frequency information and MBS reception bandwidth information.

[0358] In some embodiments, the first information is further used to indicate at least one of the following:

[0359] Do not receive MBS on multiple frequencies simultaneously;

[0360] Multiple configuration types corresponding to multiple frequencies for receiving MBS.

[0361] In some embodiments, when the terminal reports one MBS reception frequency information and one or more MBS reception bandwidth information, or multiple pairs of MBS reception frequency information and MBS reception bandwidth information, the terminal can indicate through the first information that the terminal does not receive MBS at multiple frequencies (i.e., frequency + bandwidth) at the same time.

[0362] Optionally, the terminal may also not receive MBSs on multiple frequencies (ie, frequency point + bandwidth) at the same time according to a protocol agreement.

[0363] In some embodiments, when a terminal reports one MBS reception frequency and one or more MBS reception bandwidths, or multiple pairs of MBS reception frequency and MBS reception bandwidth information, the terminal may indicate, through first information, the configuration type corresponding to the multiple frequencies (i.e., frequency + bandwidth) for receiving MBSs. Optionally, the configuration type may indicate whether it corresponds to a RedCap MBS reception CFR configuration.

[0470] Figure 5 is an interactive diagram of a reporting method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a reporting method for a communication system, the method comprising:

[0471] Step S5101: The terminal sends a first message to the network device.

[0472] The first information is used to report a first capability used by the terminal, and the first capability is used to receive a multicast broadcast service MBS.

[0473] For a detailed description of step S5101, please refer to the above embodiment description.

[0474] The steps in the embodiments of the present disclosure and their optional implementations may be arbitrarily combined with part or all of the steps in other embodiments, and may also be arbitrarily combined with the optional implementations of other embodiments.

[0475] The following is an exemplary introduction to the above method.

[0476] Step 1: The network device configures the terminal with indication information indicating whether to allow the terminal to report the terminal capability of receiving MBS.

[0477] Optionally, the network device configures the terminal with indication information of whether to allow the terminal to report the terminal capability of receiving MBS. Terms such as second information and configuration information may be used interchangeably.

[0478] The optional implementation of step 1 can refer to the optional implementation of step S2101 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0479] Step 2: When the network device configuration allows the terminal to report the terminal capability of receiving MBS, the terminal reports the terminal capability of receiving MBS used by the terminal according to the rules agreed in the protocol.

[0480] In some embodiments, the terminal may report its terminal capability for receiving the MBS through the first information.

[0481] In some embodiments, the terms such as terminal capability for receiving MBS, first capability, etc. may be used interchangeably.

[0482] Optionally, the terminal capability of receiving the MBS may be limited to the terminal capability of receiving the broadcast MBS.

[0483] Optionally, the terminal capability for receiving the MBS may be limited to shared terminal capabilities. (For example, when network B receives the MBS, the shared terminal capability reported to network A when both network B and network A are working simultaneously.)

[0484] In some embodiments, the triggering conditions for the UE to report its terminal capability for receiving MBS may include any one of the following:

[0485] The terminal is ready to receive MBS (e.g., the terminal is interested in the MBS service but has not yet received it)

[0486] The terminal is receiving MBS (e.g., the terminal is receiving MBS services according to the network configuration)

[0487] In some embodiments, the trigger condition, the first condition, etc. can be replaced with each other.

[0488] In some embodiments, the type of capability information of the terminal receiving the MBS includes any one of the following:

[0489] Type 1: The terminal reports MBS reception frequency information. The MBS reception frequency information is the frequency information of the cell receiving the MBS service (eg, the CD-SSB reception frequency of the cell receiving the MBS service).

[0490] Type 2: The terminal reports the MBS reception frequency information and at least one of the MBS reception bandwidth information and the MBS reception subcarrier spacing information.

[0491] In some embodiments, terms such as the type of information on the capability of the terminal receiving the MBS and the reporting method of the first capability may be interchangeable.

[0492] Optionally, the MBS reception frequency information may be any of the following:

[0493] The reference frequency position for receiving the MBS, for example, the absolute frequency position (absoluteFrequencyPointA) of the reference resource block (e.g., Common RB 0).

[0494] The center (or starting or ending) frequency position of the MBS reception; for example, the center (or starting or ending) frequency position of the CFR region (i.e., the frequency region configured with "cfr-ConfigMCCH-MTCH" or "cfr-ConfigMCCH-MTCH-RedCap").

[0495] The frequency corresponding to the SSB of the cell receiving the MBS; for example, the frequency of the CD-SSB of the initial BWP of the MBS cell.

[0496] Optionally, it may be agreed that type 1 is sent by the terminal according to the received “MBS continuity reception assistance information” (eg, SIB21).

[0497] Optionally, it may be agreed that type 2 is sent when the terminal receives the “MBS frequency band configuration” (eg, CFR).

[0498] Optionally, the MBS reception bandwidth information may be any of the following:

[0499] Number of resource blocks (e.g., number of RBs)

[0500] Frequency bandwidth range (e.g., kHz or MHz)

[0501] In some embodiments, for type 2, it can be agreed that when the MBS reception bandwidth information is the number of resource blocks, the terminal must report the MBS reception subcarrier spacing information.

[0502] For example, for cell 1, the cell provides two MBS reception CFR configurations (e.g., "cfr-ConfigMCCH-MTCH" and "cfr-ConfigMCCH-MTCH-RedCap"). The terminal can receive MBS services simultaneously (or switch between the two CFRs). The MBS reception frequency information of the two MBS reception CFR configurations can be the same, but the MBS reception bandwidth information is different. In this case, the terminal reports one MBS reception frequency information and the corresponding two MBS reception bandwidth information.

[0503] In some embodiments, for type 2, the terminal may report one MBS reception frequency information and one or more MBS reception bandwidth information, or multiple pairs of MBS reception frequency information and MBS reception bandwidth information.

[0504] For example, for cell 1, the cell provides two MBS reception CFR configurations (e.g., "cfr-ConfigMCCH-MTCH" and "cfr-ConfigMCCH-MTCH-RedCap"). The terminal can receive MBS services simultaneously (or switch between the two CFRs). The MBS reception frequency information and MBS reception bandwidth information of these two MBS reception CFR configurations can be different. Therefore, the terminal reports two pairs of MBS reception frequency information and MBS reception bandwidth information.

[0505] In some embodiments, when a terminal reports one MBS reception frequency and one or more MBS reception bandwidths; or reports multiple pairs of MBS reception frequency and MBS reception bandwidth information, the terminal may indicate or agree upon a protocol that the terminal does not simultaneously receive MBSs on these multiple frequencies (i.e., frequency + bandwidth). Alternatively, the terminal may indicate the configuration type corresponding to the MBS reception on these multiple frequencies (i.e., frequency + bandwidth) (e.g., whether they correspond to the RedCap MBS reception CFR configuration).

[0506] The optional implementation of step 2 can refer to the optional implementation of step S2102 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0507] Step 3: The network side sends configuration information to the terminal based on the terminal capability information for receiving MBS reported by the terminal in step 2.

[0508] In some embodiments, terms such as configuration information and third information can be used interchangeably.

[0509] In the above embodiment, the network sends configuration information to the terminal according to the terminal capability information for receiving the MBS reported by the terminal, thereby avoiding configuration that conflicts with the terminal capability for receiving the MBS.

[0510] For example, the service frequency of the terminal configured on the network side and the frequency of the terminal capability of "receiving MBS" need to belong to the same band combination.

[0511] The optional implementation of step 3 can refer to the optional implementation of step S2103 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0512] The reporting method involved in the embodiments of the present disclosure may include at least one of steps 1 to 3. For example, step 2 may be implemented as an independent embodiment, step 1 + step 2 may be implemented as an independent embodiment, and step 2 + step 3 may be implemented as an independent embodiment, but are not limited thereto.

[0513] In some embodiments, step 1 and step 3 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0514] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated.

Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.
