The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0117] Optionally, the core network device can include, but is not limited to, at least one of the following: a core network node, a core network function, a Mobility Management Entity (MME), an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a User Plane Function (UPF), a Policy Control Function (PCF), a Policy and Charging Rules Function (PCRF), an Edge Application Server Discovery Function (EASDF), a Unified Data Management (UDM), a Unified Data Repository (UDR), a Home Subscriber Server (HSS), a Centralized network configuration (CNC), a Network Repository Function (NRF), a Network Exposure Function (NEF), a Local NEF (or L-NEF), a Binding Support Function (BSF), an Application Function (AF), a Network Data Analytics Function (NWDAF), a Location Management Function (LMF), an Evolved Serving Mobile Location Centre (E-SMLC), and the like. It should be noted that only the core network device in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the core network device is not limited.

[0118] For better understanding of the embodiments of the present application, the UE capability is described.

[0119] According to the network element used by the UE capability, the UE capability is also divided into a core network (CN) capability and a radio access network (RAN) capability. The RAN capability can also be referred to as a radio access capability, which is the capability of the terminal for transmission with the radio access network element.

[0120] The UE capability includes mandatory UE capability and optional UE capability. The mandatory UE capability is a function / feature / procedure that the terminal is required to support to ensure that the terminal and the network side can perform basic communication, and the mandatory UE capability does not need to be reported. The optional UE capability is a function / feature / procedure that the UE can optionally support considering different terminal types, communication scenarios, requirements, and the like. The optional UE capability needs to be reported to the network side, so that the network side sends configuration parameters supported by the UE.

[0121] For better understanding of the embodiments of the present application, the UE radio access capability reporting is described.

[0122] The radio access capability of the UE includes a large number of parameters, such as bands supported by the UE, band combinations (BCs) supported by the UE, and technical features supported by the UE. For some technical features, the UE needs to report whether the feature is supported according to a per band, or a per band combination, or a per band per band combination, or a per carrier per band per band combination, and the like.

[0123] In order to reduce the signaling overhead caused by reporting the radio access capability of the UE on the air interface, the radio access capability reported by the UE is stored in the core network. When the service base station of the UE is changed, the changed service base station obtains the radio access capability of the UE from the core network. Only when the core network also does not store the radio access capability of the UE, the changed service base station requests the UE to report its radio access capability from the UE. The base station requests the UE to report the radio access capability by sending a UE capability request (UECapabilityEnquiry) to the UE. After receiving the UE capability request (UECapabilityEnquiry), the UE sends UE capability information (UECapabilityInformation), which carries the radio access capability of the UE. Specifically, the UE capability information (UECapabilityInformation) can be as follows: Figure 2indicated.

[0124] The radio access capability of the UE stored in the core network is generally considered not to change dynamically and is regarded as a relatively static capability.

[0125] When reporting the radio access capability, the UE reports the supported band combination, such as the band combination {A, B, Z}, and for the band combination, the UE also reports the corresponding Feature Set Combinations, which are the allocation / combination of the terminal capability on each band when the terminal works in the band combination. Since the terminal needs to report the corresponding Feature Set Combinations for each band combination, the signaling overhead is very large. Considering that the Feature Set Combinations of different band combinations may be similar or even the same, when reporting the radio access capability, the UE reports a Feature Set Combinations pool, which includes a plurality of Feature Set Combinations, and each Feature Set Combinations is given by a Feature Set Combinations identifier. Then, for each band combination, the UE can index a Feature Set Combinations in the Feature Set Combinations pool through the Feature Set Combinations ID, so as to achieve the reuse of the same Feature Set Combinations on different band combinations.

[0126] Further, when reporting each Feature Set Combinations in the Feature Set Combinations pool, each Feature Set Combinations is also according to the Feature Set Combinations Figure 3The per band is reported as shown, and a Feature Set Combinations corresponds to a band combination of 3 bands, and the Feature Set Combinations includes: a Feature Set of a first band, a Feature Set of a second band, and a Feature Set of a third band. In order to further reduce the reporting overhead of the per band Feature Set, the UE also reports a Feature Set pool, so that if the Feature Sets of the first band and the second band are the same, i.e., include N same parameters, the UE only needs to report the Feature Set once, and then reports the index of the Feature Set in the Feature Set pool for the first band and the second band respectively.

[0127] For better understanding of the embodiments of the present application, the use scenarios of the embodiments of the present application are exemplified, but the use scenarios of the embodiments of the present application are not limited to the examples.

[0128] In actual communication, there is a case that two UEs have ideal backhaul conditions (such as WiFi connection, Bluetooth connection, wired connection, etc.), at this time, the capability or hardware of one UE (such as an assistant UE) can be used to assist the communication of another UE (such as an anchor UE) with the network side, to improve the transmission reliability, throughput of the anchor UE, or reduce the power consumption of the anchor UE. Specifically, the relationship between the assistant UE and the anchor UE is UE aggregation, and in the aggregation case, the anchor UE has a capability that exceeds the UE capability stored at the network side (such as a core network). When the two UEs are aggregated, the network side does not know the assistant UE aggregated with the anchor UE, that is, the network side cannot perceive the change of the capability of the anchor UE, so that the available capability of the anchor UE cannot be fully utilized, affecting the transmission rate, transmission stability and other performances of the anchor UE.

[0129] For better understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0130] Figure 4is a schematic flowchart of a capability reporting method 200 according to an embodiment of the present application, as shown, the capability reporting method 200 can include at least part of the following contents: Figure 4

[0131] S210, a terminal reports a first radio access capability;

[0132] S220, an access network device receives the first radio access capability from the terminal, or the access network device obtains the first radio access capability of the terminal from a core network device;

[0133] S230, after the terminal reports the first radio access capability, the terminal reports first information to the access network device; wherein the first information is used to indicate a second radio access capability, the second radio access capability is an additional radio access capability of the terminal based on the first radio access capability;

[0134] S240, after the access network device obtains the first radio access capability, the access network device receives the first information from the terminal.

[0135] It should be understood that Figure 4 The steps or operations of the capability reporting method 200 are shown, but these steps or operations are only examples, and the present application can also perform other operations or Figure 4 variations of each operation in the above.

[0136] In some implementations, in the above S210, the terminal reports the first radio access capability to the access network device, in this case, in the above S220, the access network device receives the first radio access capability from the terminal.

[0137] In other implementations, in the above S210, the terminal reports the first radio access capability to the core network device, in this case, in the above S220, the access network device obtains the first radio access capability of the terminal from the core network device.

[0138] In some implementations, the terminal reports the first radio access capability to a first access network element at a certain time (such as after booting and initial registration), the first access network element sends the first radio access capability to a core network element for storage, and then the terminal disconnects the RRC connection with the first access network element, when the terminal subsequently establishes or resumes the RRC connection at a second access network element, the second access network element obtains the first radio access capability of the terminal from the core network element.

[0139] ​It should be noted that the first radio access capability described in the embodiments of the present application does not refer to a certain capability, but refers to the overall radio access capability of the terminal, which includes a series of radio capability parameters, such as supported frequency points, supported frequency band combinations, supported features, and the like.

[0140] The second radio access capability described in the embodiments of the present application can be an additional radio access capability of the terminal based on the first radio access capability.

[0141] In some implementations, the first radio access capability or the second radio access capability can be the capability of a certain feature (for example, supported band) or the capability of multiple features (for example, supported band and supported band combination).

[0142] Optionally, the first radio access capability and the second radio access capability can correspond to the same feature.

[0143] Optionally, the terminal can have an additional radio access capability based on the first radio access capability in some special forms. For example, for a terminal with a folding function, the terminal has the first radio access capability in the folded form, and has an additional radio access capability based on the first radio access capability in the unfolded or expanded or opened form. In other words, the terminal with the folding function increases the radio access capability when it is folded or expanded or opened.

[0144] Optionally, the terminal can have an additional radio access capability based on the first radio access capability in some special scenarios. For example, the terminal has the first radio access capability when it is not in the aggregation state, and can obtain the available radio access capability from other terminals (connected in a wireless or wired manner) in the aggregation scenario, that is, the terminal has an additional radio access capability based on the first radio access capability in the aggregation scenario. In this case, the additional radio access capability of the terminal can be part or all of the radio access capability of the other terminal. For example, in the case of aggregation of UE1 and UE2, for UE1, the first radio access capability is the radio access capability of UE1, and the second radio access capability is part or all of the radio access capability of UE2.

[0145] Specifically, in the aggregation scenario, at least two UEs have ideal backhaul conditions (such as WiFi, Bluetooth, wired connection, etc.), and the capability / hardware of one or more UEs (which can be referred to as assistant UEs (assistant UEs)) can be used to assist the communication of another UE (which can be referred to as an anchor UE (anchor UE)) with the network side, so as to improve the transmission reliability, throughput, or reduce the power consumption of the anchor UE.

[0146] The wireless access capability (such as the first wireless access capability, the second wireless access capability, etc.) described in the embodiments of the present application can include, but is not limited to, at least one of the following:

[0147] The bands supported by the terminal, the band combinations supported by the terminal, the maximum data rate supported by the terminal, the maximum transmit power supported by the terminal, the bandwidth supported by the terminal, the number of Multiple Input Multiple Output (MIMO) layers supported by the terminal, the features supported by the terminal, and the measurement capabilities supported by the terminal (such as the frequency points supporting measurement, the number of frequency points, whether the measurement will affect scheduling, etc.).

[0148] For example, the first wireless access capability of the terminal indicates that bands A, B, and C are supported, and the second wireless access capability indicates that band D is supported. The network side knows that the terminal supports bands A, B, C, and D.

[0149] For another example, the first wireless access capability of the terminal indicates that the MIMO capability is 2, and the second wireless access capability indicates that the MIMO capability is 4 (or indicates an increase of 2). The network side knows that the terminal supports a MIMO capability of 4. Specifically, since the granularity of the MIMO capability can be reported per CC per band per BC, the indication of the additional capability can also be one-to-one corresponding, that is, the additional MIMO capability is reported per CC per band per BC.

[0150] In some embodiments, the terminal sends the first information to the current serving access network device in an RRC connected state. The first information can be carried by one of the following:

[0151] Radio Resource Control (RRC) message, Media Access Control (MAC) signaling, and physical layer signaling.

[0152] For example, the first information can be UE assistance information, UE information response information, and UE capability information.

[0153] In some embodiments, the terminal reports the first information in a RRC connection setup, resume, reestablishment, handover procedure, so that the access network device can utilize the additional capability of the terminal as soon as possible. For example, the first information can be carried by one of the following: RRC connection setup complete message, RRC reconfiguration complete message, RRC connection reestablishment complete message, RRC connection resume complete message, RRC connection resume request message, message 1 in four-step random access, message A in two-step random access, logical channel identifier (LCID).

[0154] In some embodiments, after the terminal reports the first information, the terminal receives a specific configuration information, which is used to configure parameters related to the second radio access capability.

[0155] In the embodiments of the present application, the terminal can report its additional radio access capability, i.e., the second radio access capability, based on the first radio access capability, so as to avoid the situation that the network side is unaware of the second radio access capability of the terminal, and thus the radio access capability of the terminal cannot be fully utilized, thereby improving the transmission rate and transmission stability of the terminal.

[0156] In some embodiments, the first information includes, but is not limited to, at least one of the following:

[0157] The second radio access capability;

[0158] First characteristic information, the first characteristic information is used to determine the second radio access capability from a saved characteristic set combination or characteristic set pool by the access network device;

[0159] First capability identifier, the first capability identifier is used to indicate the second radio access capability.

[0160] As an implementation, the second radio access capability can be directly reported in the first information, so as to simplify the processing complexity of the network side, and be suitable for the case where the second radio access capability is less.

[0161] As another implementation, in the case that the first radio access capability reported by the terminal includes a feature set combination pool and a feature set pool, the first information sent by the terminal can carry first feature information. For example, the first feature information is a feature set combination ID, and the access network device determines the feature set combination currently supported by the terminal (i.e., the second radio access capability) based on the feature set combination ID reported by the terminal and the feature set combination pool saved by the access network device. For example, the feature set combination uniquely determined from the feature set combination pool saved by the access network device based on the feature set combination ID reported by the terminal is the feature set combination currently supported by the terminal. Or, the first feature information is a feature set ID, and the access network device determines the feature set currently supported by the terminal (i.e., the second radio access capability) based on the feature set ID reported by the terminal and the feature set pool saved by the access network device. For example, the feature set uniquely determined from the feature set pool saved by the access network device based on the feature set ID reported by the terminal is the feature set currently supported by the terminal. This embodiment can reduce signaling overhead and is suitable for the case that the first radio access capability and the second radio access capability of the terminal support the same feature set or feature set combination. It should be noted that the feature set combination ID or feature set ID carried in the first information can be more than one. For example, the terminal can report multiple feature set combination IDs, each of which corresponds to a specific band combination. For another example, the terminal can report the corresponding feature set ID for at least one band in a certain band combination.

[0162] It should be noted that the association between the feature set combination ID and the feature set combination pool, and the association between the feature set ID and the feature set pool, can refer to the above description of the reporting of the radio access capability of the terminal. For brevity, it will not be repeated here.

[0163] As another implementation, the first information can carry the first capability identifier, which can be a terminal capability identifier (UE capability ID) in Radio Capabilities Signaling Optimization (RACS), in which case the core network supports RACS function. For example, the access network device transfers the first capability identifier to the core network device after receiving it, and then the core network device uniquely determines a set of radio access capabilities, i.e., second radio access capabilities, based on the first capability identifier, and transfers the second radio access capabilities to the access network device. This implementation can reduce signaling overhead and is applicable to the case where the second radio access capabilities are stored in the core network device. For example, in the UE aggregation scenario, when two UEs are not aggregated, the first radio access capabilities of each UE are stored in the core network device, and when the two UEs are aggregated, the anchor UE reports the radio access capability identifier of the secondary UE to the network side, and the network side queries the radio access capability of the secondary UE according to the radio access capability identifier and sends the capability information to the access network device as the second radio access capability of the anchor UE.

[0164] In some embodiments, the capability reporting method 200 further includes: reporting, by the terminal, updated first information to the access network device;

[0165] The updated first information is used to indicate the updated second radio access capabilities.

[0166] For example, at time 1, UE 1 aggregates with UE 2, and UE 1 indicates the radio access capability of UE 2 through the first information. At time 2, UE 1 aggregates with UE 3, and then UE 1 updates the first information and indicates the radio access capability of UE 3 through the updated first information.

[0167] In this embodiment, the terminal can indicate the updated second radio access capabilities by reporting the updated first information, so that the network side can learn the updated second radio access capabilities in a timely manner.

[0168] In some embodiments, the terminal reports the updated first information to the access network device according to a first timer, wherein the first timer is started after the terminal reports the first information, and the terminal is allowed to report the updated first information in the case where the first timer expires. Optionally, the terminal is prohibited or not allowed to report the updated first information during the running of the first timer.

[0169] In the embodiment, the terminal reports the updated first information to the access network device according to the first timer, so that the terminal can be prevented from frequently updating the first information.

[0170] Optionally, the duration of the first timer can be configured by the network side or be agreed by a protocol.

[0171] In some embodiments, the terminal starts the first timer immediately after reporting the first information, or the terminal starts the first timer after a first duration after reporting the first information. Optionally, the first duration can be configured by the network side or be agreed by a protocol.

[0172] In some embodiments, the first information includes at least two sets of the second radio access capability.

[0173] For example, the information elements included in each of the at least two sets of the second radio access capability can be different.

[0174] For another example, the information elements included in each of the at least two sets of the second radio access capability can be the same, but the values of at least some of the information elements in different sets of the second radio access capability are different.

[0175] In some embodiments, the capability reporting method 200 further includes:

[0176] The terminal sends second information to the access network device, where the second information is used to indicate the second radio access capability applied by the terminal in the at least two sets of the second radio access capability.

[0177] In the embodiment, the terminal can send the second information based on actual needs to indicate the second radio access capability applied by the terminal in the at least two sets of the second radio access capability. In the case where the second radio access capability needs to be updated, only the updated second information needs to be reported, and the first information does not need to be repeatedly reported.

[0178] Optionally, the second information can be carried by an RRC message, a MAC CE or physical layer signaling. The second information can be sent after entering an RRC connected state, or can be sent in a process of establishing, resuming, reestablishing or switching an RRC connection. The specific message can refer to the sending of the first information, which will not be described herein.

[0179] In some embodiments, the capability reporting method 200 further includes:

[0180] The terminal reports updated second information to the access network device.

[0181] The updated second information is used to indicate the second radio access capability applied by the updated terminal in the at least two sets of second radio access capabilities.

[0182] In this embodiment, the terminal can report the updated second information to indicate the second radio access capability applied by the updated terminal, so that the network side can learn the updated second radio access capability in time.

[0183] In some embodiments, the terminal reports the updated second information to the access network device according to a second timer; the second timer is started after the terminal reports the second information, and the terminal is allowed to report the updated second information when the second timer expires. Optionally, the terminal is prohibited or not allowed to report the updated second information during the running of the second timer.

[0184] In this embodiment, the terminal reports the updated second information to the access network device according to the second timer, which can avoid frequent updating of the second information by the terminal.

[0185] Optionally, the duration of the second timer can be configured by the network side or agreed by a protocol.

[0186] In some embodiments, before the terminal reports the first information to the access network device, the capability reporting method 200 further includes:

[0187] The terminal receives first configuration information from the access network device;

[0188] The first configuration information is used to indicate the content allowed to be carried by the first information.

[0189] In this embodiment, the first configuration information can be used to indicate the content allowed to be carried by the first information, which can avoid the terminal carrying the content not interested by the network in the first information, thereby reducing the signaling overhead of the first information.

[0190] Optionally, the first configuration information can be used to configure a filter, wherein the filter is used to limit the content carried by the first information, or the filter is used to screen the content allowed to be carried by the first information. For example, the filter can be an additional capability interested by the network side, such as a band interested by the network side or a band combination interested by the network side.

[0191] Optionally, the first configuration information is used to indicate whether the terminal is allowed to report the second radio access capability, or is used to indicate the second radio access capability allowed to be reported by the terminal.

[0192] Optionally, the first configuration information can be carried by the following messages:

[0193] RRC reconfiguration message, RRC connection resume message.

[0194] In some embodiments, the S230 can specifically include:

[0195] The terminal reports the first information to the access network device in at least one of the following cases:

[0196] The network side allows the terminal to report the second radio access capability;

[0197] The network side requests the terminal to report the second radio access capability.

[0198] In some embodiments, before the terminal reports the first information to the access network device, the capability reporting method 200 further includes:

[0199] The terminal sends first indication information to the access network device;

[0200] The first indication information is used to indicate whether the terminal has the second radio access capability.

[0201] In this embodiment, the terminal can send the first indication information to let the network side know whether the terminal has the second radio access capability in time, so that the network side can enable the reporting of the first information as soon as possible in the case that the terminal has the second radio access capability, so that the network side can obtain the first information in time.

[0202] In some embodiments, the first indication information is carried by one of the following:

[0203] RRC connection setup complete message, RRC reconfiguration complete message, RRC connection reestablishment complete message, RRC connection resume complete message, RRC connection resume request message, message 1 (Msg 1) in four-step random access, message A (Msg A) in two-step random access, logical channel identity (LCID), terminal assistance information.

[0204] In some embodiments, before the terminal sends the first indication information to the access network device, the capability reporting method 200 further includes:

[0205] The terminal receives second configuration information from the access network device;

[0206] The second configuration information is used to indicate whether the terminal is allowed to send the first indication information in at least one of the following procedures: an RRC connection establishment procedure, an RRC connection recovery procedure, and an RRC connection reestablishment procedure.

[0207] Optionally, the second configuration information can be carried through broadcast or dedicated signaling (such as an RRC release message).

[0208] In some embodiments, before the terminal reports the first information to the access network device, the capability reporting method 200 further includes:

[0209] The terminal sends second indication information to the access network device.

[0210] The second indication information is used to indicate that the terminal supports reporting the second radio access capability.

[0211] In this embodiment, the terminal can send the second indication information to enable the network side to learn in a timely manner that the terminal supports reporting the second radio access capability, so that the network side can enable the reporting of the first information as soon as possible, so that the network side can obtain the first information in a timely manner.

[0212] Optionally, the second indication information can be carried through UE capability information.

[0213] In some embodiments, the capability reporting method 200 further includes:

[0214] The terminal sends third information to the access network device.

[0215] The third information is used to indicate capability information in the first radio access capability that cannot coexist with the second radio access capability, or the third information is used to indicate capability information in the first radio access capability that can coexist with the second radio access capability.

[0216] For example, considering that the transmission of the assistant UE can cause certain interference to the transmission of the anchor UE in an aggregation scenario. Therefore, in addition to reporting the first information, the anchor UE can report third information, which is used to indicate capability information in the first radio access capability that cannot coexist with the second radio access capability, or is used to indicate capability information in the first radio access capability that can coexist with the second radio access capability. For example, the third information can indicate that a frequency band combination {A+B} in the first radio access capability can coexist with a frequency band X in the second radio access capability, but a frequency band combination {A+C} in the first radio access capability cannot coexist with the frequency band X in the second radio access capability.

[0217] In some embodiments, all of the first radio access capabilities of the terminal cannot coexist with the second radio access capability, and thus when the terminal reports or activates the second radio access capability, the network side can be explicitly or implicitly indicated that the first radio access capability cannot be used or is temporarily not supported.

[0218] In some embodiments, the capability reporting method 200 further includes:

[0219] The terminal sends fourth information to the access network device, wherein the fourth information is used to indicate at least one of the following: whether to apply the second radio access capability, and delete the first information.

[0220] Optionally, the fourth information can also be used to indicate whether to activate the second radio access capability.

[0221] In some embodiments, the fourth information can be carried by one of the following:

[0222] RRC message, MAC signaling, and physical layer signaling.

[0223] Therefore, in the embodiments of the present application, after the terminal reports the first radio access capability, the terminal reports the first information to the access network device, wherein the first information is used to indicate the second radio access capability, and the second radio access capability is the radio access capability that the terminal additionally has on the basis of the first radio access capability. Specifically, the terminal can report the radio access capability that it additionally has on the basis of the first radio access capability, so as to avoid the situation that the network side does not know the second radio access capability of the terminal, and thus the radio access capability of the terminal cannot be fully utilized, thereby improving the transmission rate and transmission stability of the terminal.

[0224] The technical solutions of the capability reporting method 200 of the present application are described below by way of embodiments 1 to 3.

[0225] Embodiment 1 is described by way of example, in which the terminal reports the first information, and the first information includes at least one of the following: the second radio access capability; the first characteristic information, which is used for the access network device to determine the second radio access capability from the saved characteristic set combination or characteristic set pool; and the first capability identifier, which is used to indicate the second radio access capability.

[0250] Specifically, the terminal reports at least two sets of second radio access capabilities through the first information.

[0252] Specifically, for example, each of the at least two sets of second radio access capabilities can include different information elements.

[0253] Specifically, for another example, each of the at least two sets of second radio access capabilities can include the same information elements, but the values of at least part of the information elements of different sets of second radio access capabilities are different.

[0254] S2-3. When the terminal needs to enable the second radio access capability, the terminal sends second information to the access network device, and the second information is used to indicate that the terminal applies a first set of second radio access capabilities in the at least two sets of second radio access capabilities.

[0289] In some other implementations, in the S310, the terminal reports at least two sets of the third radio access capabilities to the first access network element at a certain time (e.g., when initially registering after powering on), and the first access network element sends the at least two sets of the third radio access capabilities to the core network element for storage. Then, the terminal disconnects the RRC connection with the first access network element, and when the terminal subsequently establishes or resumes the RRC connection with the second access network element, the second access network element obtains the at least two sets of the third radio access capabilities of the terminal from the core network element (the terminal can subsequently report the fifth information to the second access network element). Alternatively, when the terminal subsequently establishes or resumes the RRC connection with the second access network element, the terminal sends the fifth information to the second access network element through the AS layer signaling, the fifth information carries the index / identification information corresponding to the third radio access capability applied by the terminal, the second access network element sends the fifth information to the core network device, the core network device queries the third radio access capability applied by the terminal based on the fifth information, and pushes the third radio access capability to the second access network device. Alternatively, when the terminal subsequently establishes or resumes the RRC connection with the second access network element, the terminal sends the fifth information to the core network element through the NAS layer signaling, the fifth information carries the index / identification information corresponding to the third radio access capability applied by the terminal, the core network device queries the third radio access capability applied by the terminal based on the fifth information, and pushes the third radio access capability to the second access network device.

[0290] Optionally, the index information corresponding to the multiple sets of the third radio access capabilities reported by the terminal can be explicitly indicated by the terminal or mapped in a preset manner (e.g., according to the bit order of the multiple sets of the third radio access capabilities in the message, or according to different information elements (IEs) carried by the third radio access capabilities, such as high-order capability and low-order capability IEs). The AS layer and the NAS layer of the terminal can transmit the index / identification information corresponding to the third radio access capabilities to each other when needed, so as to accurately send the fifth information.

[0291] In the embodiments of the present application, the terminal can correspond to different third wireless access capabilities in different forms. For example, for a terminal with folding function, the terminal has a set of third wireless access capabilities in the folded form, and has another set of third wireless access capabilities in the unfolded or expanded or unfolded form. In other words, the terminal with folding function has at least two sets of third wireless access capabilities. For example, the folding screen of the terminal has two different sets of third wireless access capabilities in the open and closed states.

[0292] In the embodiments of the present application, the terminal can have at least two sets of third wireless access capabilities in different scenarios. For example, the terminal can obtain the available wireless access capabilities from other terminals connected (wirelessly or by wire) to the terminal in the aggregation scenario, that is, the terminal has a set of third wireless access capabilities in the aggregation scenario. In this case, the additional wireless access capabilities of the terminal can be part or all of the wireless access capabilities of the other terminals. In the non-aggregation scenario, the terminal has another set of third wireless access capabilities.

[0293] It should be noted that in the aggregation scenario, at least two UEs have ideal backhaul conditions (such as WiFi, Bluetooth, wired connection, etc.), and the capabilities / hardware of one or more UEs (which can be referred to as assistant UEs) can be used to assist the communication of another UE (which can be referred to as anchor UE) with the network side, so as to improve the transmission reliability, throughput, or reduce the power consumption of the anchor UE.

[0294] In the embodiments of the present application, a set of third wireless access capabilities can include but is not limited to at least one of the following:

[0295] The bands supported by the terminal, the band combinations supported by the terminal, the maximum data rate supported by the terminal, the maximum transmit power supported by the terminal, the bandwidth supported by the terminal, the number of MIMO layers supported by the terminal, the features supported by the terminal, and the measurement capabilities supported by the terminal (such as the number of frequency points, the number of frequency points, whether the measurement will affect scheduling, etc.).

[0296] In some embodiments, the at least two sets of third wireless access capabilities can be carried by Access Stratum (AS) layer signaling or NAS layer signaling. For example, the at least two sets of third wireless access capabilities can be reported by a terminal capability information message.

[0297] For example, each set of third wireless access capabilities in the at least two sets of third wireless access capabilities can include different information elements.

[0298] Specifically, for example, the information elements included in each of the at least two sets of third radio access capabilities can be the same, but the values of at least part of the information elements of different sets of third radio access capabilities are different.

[0299] Optionally, the fifth information can include a specific bit for indicating that the terminal switches the third radio access capability. For example, a value of 0 is used to indicate that the terminal does not switch the third radio access capability, and a value of 1 is used to indicate that the terminal switches the third radio access capability; or a value of 1 is used to indicate that the terminal does not switch the third radio access capability, and a value of 0 is used to indicate that the terminal switches the third radio access capability.

[0300] Optionally, the fifth information can indicate one set of the third radio access capability applied or activated by the terminal, meaning that the third radio access capability not activated is in a state of deactivation / non-support / non-application by default. Optionally, the fifth information can indicate multiple sets of the third radio access capability applied or activated by the terminal.

[0301] In some embodiments, the fifth information is carried by one of the following:

[0302] an RRC connection setup complete message, an RRC reconfiguration complete message, an RRC connection reestablishment complete message, an RRC connection resume complete message, an RRC connection resume request message, a message 1 (Msg 1) in a four-step random access, a message A (Msg A) in a two-step random access, an LCID, terminal assistance information, a non-access stratum (NAS) message.

[0303] In some embodiments, before the terminal reports the fifth information, the capability reporting method 300 further includes:

[0304] The terminal receives third configuration information.

[0305] The third configuration information is used to indicate whether the terminal is allowed to send the fifth information in at least one of the following processes: an RRC connection establishment process, an RRC connection recovery process, and an RRC connection reestablishment process.

[0306] Specifically, for example, the terminal receives third configuration information from the access network device.

[0307] Optionally, the third configuration information can be carried by broadcast or dedicated signaling (such as an RRC release message).

[0308] In some embodiments, when the access network device receives the at least two sets of third radio access capabilities from the terminal, the capability reporting method 300 further includes:

[0309] The access network device sends the at least two sets of third radio access capabilities to the core network device.

[0310] In some embodiments, in a case where the core network device receives fifth information from the terminal, the capability reporting method 300 further includes:

[0311] The core network device sends sixth information to the access network device; wherein the sixth information is used to indicate the third radio access capability applied by the terminal in the at least two sets of third radio access capabilities.

[0312] In the present embodiment, the access network device can learn the third radio access capability applied by the terminal in the at least two sets of third radio access capabilities through the sixth information.

[0313] Therefore, in the present embodiment, after the terminal reports the at least two sets of third radio access capabilities, the terminal reports fifth information; wherein the fifth information is used to indicate at least one of the following: the third radio access capability applied by the terminal in the at least two sets of third radio access capabilities; and the third radio access capability switched by the terminal. Specifically, the terminal can report the at least two sets of third radio access capabilities possessed by the terminal, and indicate the third radio access capability currently applied or the third radio access capability switched, so as to avoid the situation that the radio access capability of the terminal cannot be fully utilized due to the unawareness of the at least two sets of third radio access capabilities possessed by the terminal on the network side, thereby improving the transmission rate and transmission stability of the terminal.

In the present embodiment, the capability reporting device is taken as an example to illustrate the capability reporting device provided in the present embodiment.
