[0091] The technical solutions provided by the present application will be further described below in combination with the drawings and embodiments. It should be understood that the system structure and service scenarios provided in the embodiments of the present application are mainly to explain some possible implementation manners of the technical solutions of the present application, and should not be interpreted as the only limitation of the technical solutions of the present application. Those skilled in the art can know that the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems as the network architecture evolves and new service scenarios appear.

[0092] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as long term evolution (long term evolution, LTE) system and NR system, etc., which are not limited here. It should be noted that the present application can be applied to independently deployed 5G or LTE system, and also applied to non-independently deployed 5G or LTE system, such as dual connectivity (dual-connectivity, DC) scenario.

[0093] In the embodiments of the present application, the terminal device can be a device with wireless transceiving function or a chip that can be arranged in any device, and can also be referred to as a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or a user apparatus. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiving function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, etc.

[0094] The access network device can be a next generation node B (gNB) in an NR system, and can be an evolved node B (eNB) in an LTE system, etc.

[0095] Figure 1 A network architecture diagram suitable for the present application is shown in FIG. 1. As shown in FIG. 1, a terminal device can access an access network device to obtain services of an external network (for example, a data network (DN)) through the access network device, or communicate with other devices through the access network device, such as communicating with other terminal devices. Figure 1

[0096] In the embodiments of the present application, the capability of the terminal device can be a static capability determined according to factors such as hardware and / or software configuration of the terminal device, and is used to indicate whether the terminal device has support for a certain feature or feature set. For example, the maximum bandwidth supported by the terminal device is 100 MHz if the maximum bandwidth supported by the radio frequency channel of the terminal device is 100 MHz.

[0097] ​The capability of the terminal device can also refer to a dynamically configured capability. For example, the capability of the terminal device can be dynamically configured according to factors such as a working environment. For example, after the terminal device is registered in the network, in some scenarios, it can also be desired to change the capability information. For example, the terminal device has an overheating problem; or the terminal device reduces power consumption in order to save power; or the terminal device needs to adjust the capability due to hardware sharing requirements; or the terminal device needs to change the carrier frequency due to a serious interference problem; or the terminal device changes the capability due to service requirements, and the like. The network device can reduce the capability of the terminal device through high-layer signaling or medium access control (MAC) layer signaling or physical (PHY) layer signaling, and the like.

[0098] In the embodiments of the present application, the interaction between the network device and the terminal device is taken as an example for description, and the operations performed by the network device can also be performed by a chip or a module inside the network device, and the operations performed by the terminal device can also be performed by a chip or a module inside the terminal device.

[0099] In combination with the foregoing description, as shown in Figure 2 FIG. 1 is a flowchart of a communication method provided by an embodiment of the present application. Referring to Figure 2 , the method comprises the following steps.

[0100] S201: The terminal device determines indication information.

[0101] In the embodiments of the present application, the indication information can be carried in a capability adjustment request message or auxiliary information, or the indication information can also refer to the auxiliary information.

[0102] The capability adjustment request message is used to request adjustment of the capability of the terminal device. The auxiliary information can also be referred to as UE auxiliary information, and is uniformly referred to as auxiliary information in the following. The terminal device can report the desired configuration parameters (for example, the first parameter set below) to the network device through the auxiliary information, and the network device can refer to the auxiliary information reported by the terminal device to perform RRC reconfiguration, so that the terminal device can avoid updating the capability through a registration process, thereby reducing the latency and signaling overhead.

[0103] The above is only an example, and the indication information can also be carried by other messages or information, which is not limited in the embodiments of the present application.

[0104] The indication information includes a first parameter set, and the first parameter set is used for the network device to adjust a configuration parameter of the terminal device based on the first parameter set. For example, the first parameter set can include one or more of the following: in-device coexistence (IDC) assistance information; discontinuous reception (DRX) preference parameters; maximum aggregated bandwidth preference parameters; maximum carrier number preference parameters; maximum multi-input multi-output (MIMO) layer number preference parameters; minimum scheduling offset parameters; radio resource control (RRC) state preference parameters; sidelink assistance information, and the like. The above is only an example, and the first parameter set can also include other contents, which will not be illustrated one by one here.

[0105] The indication information can also include at least one of the first information or the second information. The first information is used to indicate an emergency degree or importance degree or urgency degree of data transmission with the network device according to the first parameter set, or to indicate an emergency degree or importance degree or urgency degree of reconfiguration according to the first parameter set.

[0106] The terminal device does not limit how to determine the emergency degree or importance degree or urgency degree. For example, the terminal device can determine the urgency degree / emergency degree / importance degree according to at least one of the temperature, power condition, carrier interference condition, radio frequency capability occupation condition, baseband resource occupation condition, or service type of the terminal device.

[0107] There can be various specific implementation manners of the first information. For example, in a first manner, the first information is an adjustment level, and the higher the adjustment level, the higher the emergency degree or importance degree or urgency degree of data transmission or changing configuration of the terminal device according to the first parameter set.

[0108] For example, four adjustment levels are predefined: level 0 to level 3, level 0 indicates that the adjustment urgency degree / emergency degree / importance degree of data transmission or changing configuration of the terminal device according to the first parameter set is the lowest, and level 3 indicates that the urgency degree / emergency degree / importance degree of data transmission or changing configuration of the terminal device according to the first parameter set is the highest. In this case, the first information can include 2 bits, and the adjustment level indicated by the first information can refer to Table 1.

[0109] Table 1

[0110] First information Adjustment level 00 Level 0 01 Level 1 10 Level 2 11 Level 3

[0111] The second way is that the first information is an adjustment factor, for example, the adjustment factor has a value range of 0-1. The greater the adjustment factor is, the higher the urgency / emergency / important degree is. For example, when the terminal device temperature increases slowly, or the terminal device power decreases slowly, or the carrier interference level is low, or the radio frequency capability occupation is low, or the baseband resource occupation is low, or the service time delay is not sensitive, the urgency / emergency / important degree can be considered to be low, and the value of the first information (the adjustment factor) can be small, for example, 0.2; and when the terminal device temperature increases quickly, or the UE power decreases quickly, or the carrier interference level is high, or the radio frequency capability occupation is high, or the baseband resource occupation is high, or the service time delay is not sensitive, the value of the first information (the adjustment factor) can be large, for example, 0.8.

[0112] In the embodiments of the application, the plurality of parameters in the first parameter set can correspond to one adjustment level / adjustment factor. For example, one or more preference parameters for energy saving are included in the first parameter set, and one adjustment level / adjustment factor is defined for energy saving, and all preference parameters related to energy saving correspond to the adjustment level / adjustment factor.

[0113] In addition, an adjustment level / adjustment factor can also be reported for each preference parameter in the first parameter set. For example, the DRX preference parameter, the maximum bandwidth preference parameter, the maximum carrier preference parameter, the maximum MIMO layer preference parameter, and the like each define a corresponding adjustment level / adjustment factor. The network device performs reconfiguration according to the adjustment level / adjustment factor corresponding to each parameter.

[0114] The third way is that the urgency or the important degree can be the probability of performing the first action or triggering the first event, and the first information can be an adjustment probability, indicating the probability that the terminal device will perform the first action or trigger the first event when the network device does not perform data transmission with the terminal device according to the first parameter set; or indicating the probability that the terminal device will perform the first action or trigger the first event when the network device does not perform reconfiguration by referring to the first parameter set, or the network device reconfigures beyond the configuration of the first parameter set. The value range of the adjustment probability can be 0%-100%. The greater the probability is, the higher the urgency / emergency / important degree of the capability adjustment is, and the greater the possibility that the terminal device performs the first action or triggers the first event is.

[0115] The specific content of the first action and the first event will be described below, and will not be described here.

[0116] In the embodiments of the application, the second information is used to indicate that the first action or the first event is performed or triggered in the case that a rejection message for the indication information is received or the case that no response information for the indication information is received.

[0117] The response information can be an RRC reconfiguration message sent by the network device after receiving the indication information, indicating that data transmission is performed with the terminal device according to the first parameter set or reconfiguration is performed with reference to the first parameter set.

[0118] The terminal device can start timing when the indication information is sent, and the timing duration is a preset duration. If the response information is received within the preset duration, and the response information indicates that data transmission is performed with the terminal device according to the first parameter set or reconfiguration is performed with reference to the first parameter set, the terminal device can stop timing. If the response information is not received within the preset duration, the first action is performed or the first event is triggered. The preset duration can be reported by the terminal device to the network device, or configured by the network device, or determined by a predefined manner, which is not limited in the present application.

[0119] The rejection message is used to indicate that the network device refuses to perform data transmission with the terminal device according to the first parameter set, or to indicate that the network device does not perform reconfiguration with reference to the first parameter set.

[0120] In the embodiments of the present application, the first action includes at least one of the following:

[0121] 1. Reporting a radio link failure; in a DC scenario, when the terminal device is in a master cell group (MCG), the terminal device can report a radio link failure of the MCG to a master node (MN); when the UE is in a secondary cell group (SCG), the terminal device reports a radio link failure of the SCG to the MN.

[0122] 2. Reporting an SCG failure;

[0123] 3. Requesting RRC connection reestablishment; the terminal device can request RRC connection reestablishment from the network device;

[0124] 4. Performing mobility registration update, that is, re-registering to the network, and the registration type is “mobility registration update”;

[0125] 5, feedback NACK, including but not limited to feedback automatic repeat request (ARQ) negative acknowledgement (NACK) at a radio link control (RLC) layer or feedback hybrid automatic repeat request (HARQ) NACK at a medium access control (MAC) layer; the feedback NACK can mean that, when the terminal device receives data at the RLC layer, ARQ NACK is fed back regardless of whether the data is correctly received; when the terminal device receives data at the MAC layer, HARQ NACK is fed back regardless of whether the data is correctly received;

[0126] 6, increase the probability of feedback NACK; including but not limited to increase the probability of feedback ARQ NACK at the RLC layer or increase the probability of feedback HARQ NACK at the MAC layer; the increase in the probability of feedback NACK can mean that, when the terminal device receives data at the RLC layer, there is a certain probability of feeding back ARQ NACK in the case of correctly receiving the data; when the terminal device receives data at the MAC layer, there is a certain probability of feeding back HARQ NACK in the case of correctly receiving the data;

[0127] 7, deactivate a secondary cell (Scell) or SCG connected by the terminal device;

[0128] 8, release the SCell or SCG connected by the terminal device;

[0129] 9, perform conditional handover.

[0130] In the embodiments of the present application, the first event includes at least one of the following:

[0132] It should be noted that in the embodiments of the present application, the terminal device can first trigger the first event and then perform the first action; or the terminal device directly performs the first action; or the terminal device triggers the first event and does not necessarily perform the first action.

[0133] It should be noted that when the indication information is auxiliary information, a message field can be added in the auxiliary information to carry the first information or the second information.

[0134] In an embodiment of the present application, the indication information may further include at least one of adjustment reason information or application duration information. The adjustment reason information is used to indicate the adjustment reason or adjustment purpose corresponding to the first parameter set; and the application duration information is used to indicate the application duration corresponding to the first parameter set.

[0135] S202: The terminal device sends instruction information to the network device.

[0136] S203: The network device receives instruction information from the terminal device.

[0137] S204: The network device determines to change the configuration of the terminal device based on the first parameter set according to at least one of the first information or the second information in the indication information.

[0138] How the network device specifically determines to change the configuration of the terminal device based on the first parameter set is not limited in the embodiments of the present application and will not be described in detail here.

[0139] It should be noted that whether the network device changes the configuration of the terminal device based on the first parameter set is determined based on actual conditions and will not be elaborated here.

[0140] Through the method provided in the embodiments of the present application, a terminal device can report first information to indicate the urgency / urgentness / importance of configuring or adjusting according to a first parameter set, and / or report the consequences of the network device not adjusting according to the configuration of the first parameter set through second information, thereby enabling the network device to reconfigure according to the first parameter set. In this way, the autonomy of the terminal device in adjusting its capabilities can be increased.

[0141] The present application also provides a pre-negotiation method for capability adjustment, in which the terminal device can pre-negotiate with the network the capabilities that the terminal device may adjust, thereby increasing the terminal device's autonomy in capability adjustment, while reducing the complexity of scheduling during capability adjustment and providing flexibility in capability adjustment, which will be described in detail below.

[0142] Combined with the previous description, such as Figure 3 FIGURE 1 is a flow chart of a communication method provided by an embodiment of the present application. Figure 3 , the method comprising:

[0143] Optionally, S301: the terminal device sends a second message to the network device, where the second message includes second indication information.

[0144] The name of the second message is not limited, for example, it can be a capability adjustment configuration message.

[0145] The second indication information indicates N capability modes, one capability mode in the N capability modes corresponds to one set of capability information, and N is an integer greater than 0. The set of capability information can include at least one of the following capabilities: a wireless capability of the terminal device; a core network capability of the terminal device; and a positioning capability of the terminal device.

[0146] It should be noted that the second message can be a capability adjustment configuration message sent by the terminal device to the network device after the terminal device establishes a connection with the network device, and the second message indicates one or more capability modes that can be adjusted by the UE to the network. One capability mode corresponds to one set of UE capability information. The capability information can include a UE wireless capability and / or a UE core network capability and / or a UE positioning capability. The message can be sent to the network device through an RRC message or a non-access stratum (NAS) message. Exemplarily, the terminal device can also send the second indication information to the network device through an independent RRC message or NAS message after establishing an RRC connection with the network device.

[0147] Exemplarily, the second indication information can also be UE capability information, or the second indication information can also be carried in the UE capability information. The terminal device can send the UE capability information to the terminal device after receiving a UE capability enquiry message from the network device.

[0148] In the embodiments of the present application, the second message can include N sets of capability information or can not include N sets of capability information. When the second message does not include N sets of capability information, a correspondence between the capability modes and the sets of capability information can be established in advance, and the correspondence between the capability modes and the sets of capability information is known to the terminal device and the network device, so that the network device can determine the corresponding set of capability information according to the capability mode.

[0149] For example, the second indication information is a bitmap, and the reported capability mode can be indicated by a bitmap. For example, there are four capability modes, namely, capability mode 0 to capability mode 3. The second indication information includes four bits, and the four bits indicate the capability mode 0 to the capability mode 3 from left to right. When the bit is 0, it indicates that the terminal device does not report the capability mode indicated by the bit; when the bit is 1, it indicates that the terminal device reports the capability mode indicated by the bit. For example, the second indication information is 1011, which indicates that the capability modes indicated by the second indication information are the capability mode 0, the capability mode 2, and the capability mode 3.

[0150] For another example, a mode identifier may be configured for each capability mode, and the second indication information includes N capability mode identifiers. For example, if the terminal device wishes to adjust its capability from capability mode 0 to capability mode 3, it may report capability mode 0 to capability mode 3 mode identifiers.

[0151] In the embodiments of the present application, the capabilities corresponding to a set of capability information sets may be a portion of the total capabilities of the terminal device, or may be the total capabilities of the terminal device. It should be noted that in the embodiments of the present application, "capability information" is a set of functions or characteristics included in a capability, which may also be referred to as a capability information set or capability parameters.

[0152] This application does not limit the content included in the capability information set. For example, the capability information set may include the following capability information: maximum carrier bandwidth; maximum number of aggregated carriers; maximum number of MIMO layers. Assume that the capability information sets corresponding to the three capability modes indicated by the second indication information can be respectively: the capability information set corresponding to capability mode 1 includes the following information: maximum carrier bandwidth of 200MHz, maximum number of aggregated carriers of 8, maximum number of MIMO layers of 4; the capability information set corresponding to capability mode 2 includes the following information: maximum carrier bandwidth of 100MHz, maximum number of aggregated carriers of 4, maximum number of MIMO layers of 2; the capability information set corresponding to capability mode 3 includes the following information: maximum carrier bandwidth of 50MHz, maximum number of aggregated carriers of 2, maximum number of MIMO layers of 1.

[0153] It should be noted that the present application may predefine an adjustable capability range, within which the terminal device determines the capability information set corresponding to each capability mode. The capability information set corresponding to the capability mode may be reported to the network device in capability signaling at the per-terminal device level, at the per-band combination (BC) level, at the per-band level, or at the per-component carrier (CC) level.

[0154] In the embodiment of the present application, the capability mode may also correspond to an adjustment reason or adjustment purpose. The adjustment reasons or adjustment purposes corresponding to different capability modes may be the same or different. For example, the capability mode adjustment reason or capability mode adjustment purpose may include but is not limited to any of the following:

[0155] The capability mode is suitable for a terminal device when the temperature of the terminal device is too high or overheated; the capability mode is suitable for energy saving; the capability mode is suitable for capability sharing of NR and a wireless local area network (WLAN); the capability mode is suitable for capability sharing of a multi-subscriber identity module (SIM) card; the capability mode is suitable for capability sharing of vehicle to everything (V2X); the capability mode is suitable for ultra-high reliability and low latency (URLLC) services; and the capability mode is suitable for reduced capability (REDCAP) services.

[0156] The terminal device can explicitly or implicitly indicate an adjustment reason or an adjustment purpose of each capability mode. When the terminal device explicitly indicates, the adjustment indication information can be carried in the second message to indicate the adjustment reason or the adjustment purpose of each capability mode. When the terminal device implicitly indicates, the adjustment reason or the adjustment purpose associated with the capability mode can be pre-agreed.

[0157] In the embodiments of the present application, the capability mode can also correspond to other information, for example, each capability mode can correspond to different peak rate levels, and the like, and details are not described herein.

[0158] Optionally, S302: The network device receives a second message from the terminal device.

[0159] S303: The network device sends a first message to the terminal device.

[0160] The name of the first message is not limited, for example, the first message can be a capability adjustment configuration confirmation message, and the like.

[0161] The first message includes first indication information. The first message or the first indication information can indicate M capability modes. For example, the first message or the first indication information can include M mode identifiers, and one mode identifier corresponds to one capability mode. The first indication information can also be used to indicate that it is allowed to request to adjust the capability of the terminal device to one of the M capability modes. M is an integer greater than 0. The allowed request to adjust the capability of the terminal device to one of the M capability modes can mean that the terminal device is allowed to send an indication message or a request message to the network device. The indication message or the request message is used to indicate that the capability mode of the terminal device is adjusted to one of the M capability modes.

[0162] It should be noted that if the terminal device sends an indication message, the indication message can indicate that the terminal device will perform data transmission or work in one of the capability modes indicated in the indication message, and the one of the capability modes belongs to the M capability modes. The one of the capability modes can also be carried in the indication message. The terminal device can not need to wait for feedback of the network device, and the terminal device considers that the network device will be configured or reconfigured according to the capability mode indicated in the indication message, and after reconfiguration, the terminal device performs data transmission or work according to the one of the capability modes indicated in the indication message. It should be noted that the feedback here refers to feedback of content of the indication message, and does not refer to ACK / NACK feedback in a normal data transmission process.

[0163] If the terminal device sends a request message, the request message can indicate that the terminal device requests to perform data transmission or work in one of the capability modes indicated in the request message. The terminal device needs to wait for feedback of the network device. When the terminal device determines, according to the feedback of the network device, that the network device will be configured according to the capability mode indicated in the request message, the terminal device performs data transmission or work according to the one of the capability modes indicated in the request message.

[0164] In an embodiment of the present application, in a possible implementation manner, when the terminal device indicates N capability modes through the second message, the M capability modes can be selected from the N capability modes reported by the terminal device to the network device, and the present application does not limit how to select. For example, the terminal device reports that the capability modes that the terminal device hopes to adjust are capability mode 1, capability mode 2, and capability mode 3; the network device can allow the terminal device to be adjusted to capability mode 1 and capability mode 3, and then indicates capability mode 1 and capability mode 3 through the first indication information.

[0165] In another possible implementation manner, the M capability modes can be predefined by a protocol or determined by the network device. The M capability modes can also exist in other determination manners, which are not enumerated one by one here.

[0166] In the implementation manner, the type of the first message can be a broadcast message or a groupcast message. The network device can indicate the M capability modes to all terminal devices accessing the network device through the broadcast message or the groupcast message, that is, simultaneously indicate the M capability modes to multiple terminal devices.

[0167] The network device can also indicate the M capability modes to terminal devices of specific types through a broadcast message or a groupcast message. The terminal devices of specific types include, but are not limited to, reduced capability (REDCAP) terminal devices, ultra-high reliability and low latency (URLLC) terminal devices, vehicle to everything (V2X) terminal devices, and the like.

[0168] Of course, the M capability modes indicated through the first message can also be for only one terminal device, and the embodiments of the present application do not limit this.

[0169] The network device can configure a corresponding capability adjustment triggering manner for each capability mode, and the second message can further include triggering information. The triggering information indicates the capability adjustment triggering manner of the M capability modes. In the embodiments of the present application, the capability adjustment triggering manner can include at least one of the following: a first triggering manner, which means that the terminal device triggers the capability adjustment. In this manner, when the terminal device needs to perform capability adjustment, the terminal device sends an indication of capability mode adjustment to the network device. A second triggering manner, which means that the terminal device requests the capability adjustment, and the network device confirms the capability adjustment. In this manner, when the terminal device needs to perform capability adjustment, the terminal device sends an indication of capability mode adjustment to the network device. If a confirmation of on-demand capability adjustment is received from the network device within a preset waiting time, it is determined that the capability mode adjustment is successful, wherein the preset waiting time is configured by the network device or set by the terminal device. A third triggering manner, which means that the network device triggers the capability adjustment. In this manner, the network device triggers whether to perform capability adjustment. When the network device needs to perform capability adjustment on the terminal device due to business needs, the network device sends an on-demand capability adjustment indication to the terminal device, indicating the adjusted capability mode.

[0170] The network device can also configure a corresponding capability recovery manner for each capability mode, and the second message can further include recovery information. The recovery information indicates the capability recovery manner of the M capability modes. In the embodiments of the present application, the capability recovery manner can include at least one of the following: a first recovery manner, which means that the capability before the capability adjustment is recovered based on a timing duration. In this manner, when the terminal device determines that the capability adjustment is successful, for example, when the RRC reconfiguration message of the network device is received, the terminal device starts a timer, and after the timer expires, the terminal device recovers to the original capability before the capability adjustment. The timing duration of the timer is the application duration of the adjusted capability mode. The network can configure the application duration of each capability mode, or the terminal device can also indicate the application duration of the capability mode to the network device when the capability adjustment is performed.

[0171] The second recovery mode refers to the capability before the capability adjustment triggered by the terminal device. In this mode, the terminal device sends a capability recovery indication to the network device, indicating that the terminal device restores to the original capability before the capability adjustment. For the capability adjustment triggered by the terminal device (the first trigger mode or the second trigger mode), the network device can configure whether to enable the capability recovery triggered by the terminal device.

[0172] The third recovery mode refers to the capability before the capability adjustment triggered by the network device. For the capability adjustment triggered by the network device (the third trigger mode), the network device can send a capability recovery indication to the terminal device, indicating that the terminal device restores to the original capability.

[0173] It should be noted that when the network device is an access network device, for the terminal triggered capability recovery and the access network device triggered capability recovery, if the access network device sends the terminal device adjusted capability mode to the core network device when performing the capability mode adjustment, the access network device can also indicate the terminal device capability after the capability recovery to the core network device.

[0174] S304: The terminal device receives the first message from the network device.

[0175] It should be noted that, Figure 3 The network device in the flow can refer to an access network device or a core device, which will be described below.

[0176] Specifically, taking the network device as an access network device as an example, as shown in Figure 4 FIG. 1 is a capability adjustment configuration flow diagram provided by the present application.

[0177] S401: The terminal device sends a capability adjustment configuration message to the access network device.

[0178] The capability adjustment configuration message includes second indication information, and the capability adjustment configuration message can refer to the second message.

[0179] In one possible implementation, the capability adjustment configuration message is an RRC message, and the terminal device can directly send the capability adjustment configuration message to the access network device; in another possible implementation, the capability adjustment configuration message is an NAS message, and the terminal device can send the capability adjustment configuration message to the core network device, and the core network device forwards the capability adjustment configuration message to the access network device.

[0180] The specific content of the N sets of capability information sets included in the second message is not limited, for example, the capability information set can include the radio frequency (RF) capability, the measurement and mobility capability, the layer 2 capability, and the like.

[0181] S402: The access network device sends a capability adjustment configuration confirmation message to the terminal device.

[0182] The capability adjustment configuration confirmation message includes first indication information, and the capability adjustment configuration confirmation message can refer to the first message.

[0183] S403: The access network device sends a capability mode configuration message to the core network device.

[0184] The capability mode configuration message can indicate M capability modes.

[0185] For example, taking the core network device as the network device, as shown in Figure 5 FIG. 1 is a capability adjustment configuration flowchart provided by the present application.

[0186] S501: The terminal device sends a capability adjustment configuration message to the core network device.

[0187] The capability adjustment configuration message includes second indication information, and the capability adjustment configuration message can refer to the second message.

[0188] The specific content of the N sets of capability information sets included in the second message is not limited, for example, the capability information sets include wireless capability of the terminal device and core network capability.

[0189] In one possible implementation manner, the capability adjustment configuration message is a NAS message, and the terminal device can send the capability adjustment configuration message to the core network device through the access network device, wherein the access network device transparently forwards the NAS message from the terminal device to the core network device.

[0190] In another possible implementation manner, the capability adjustment configuration message is an RRC message, and the terminal device can send the capability adjustment configuration message to the access network device, and the access network device forwards the capability adjustment configuration message to the core network device.

[0191] S502: The core network device sends a capability adjustment configuration confirmation message to the terminal device.

[0192] The capability adjustment configuration confirmation message includes first indication information, and the capability adjustment configuration confirmation message can refer to the first message.

[0193] It should be noted that the capability adjustment configuration confirmation message can be a NAS message, and the core network device can send the capability adjustment configuration confirmation message to the terminal device through the access network device.

[0194] S503: The core network device can further send a capability adjustment configuration assistance message to the access network device. The capability adjustment configuration assistance message indicates the M capability modes.

[0195] The M capability modes are candidate capability modes for the terminal device to adjust the capability, and are M capability modes allowed to be adjusted by the terminal device.

[0196] For example, taking the network device as the access network device, as shown in Figure 6 FIG. 1 is a capability adjustment configuration process schematic diagram provided by the present application.

[0197] S601: The terminal device sends a capability adjustment configuration message to the core network device. The capability adjustment configuration message can be the second message mentioned above.

[0198] The specific content of the N sets of capability information sets included in the second message is not limited, for example, the capability information set includes core network related capability and / or positioning capability.

[0199] In this scenario, the capability adjustment configuration message can be a NAS message, and the terminal device can directly send the capability adjustment configuration message to the core network device.

[0200] S602: The core network device sends a capability adjustment configuration confirmation message to the terminal device. The capability adjustment configuration confirmation message can be the first message mentioned above.

[0201] Through the foregoing process, the terminal device can determine the capability mode that the terminal device can select from the M capability modes for capability adjustment through pre-negotiation with the network device, thereby increasing the autonomy of the terminal device in capability adjustment. In addition, since the terminal device has reported the capability mode that can be adjusted to the network device in advance, the complexity of the network device in scheduling the terminal device with multiple capability modes can be reduced in the case of terminal capability mode change.

[0202] In the embodiment of the present application, after the terminal device and the network device pre-negotiate the M capability modes, the terminal device or the network device can trigger adjustment of the capability of the terminal device. The network device can be an access network device or a core network device. The access network device can be gNB or eNB, etc. The core network device can be an access and mobility management function (AMF) network element or a location management function (LMF) network element, etc. The following describes different cases.

[0203] Implementation manner one:

[0204] In the capability adjustment configuration process, the capability adjustment can be triggered by the terminal device, that is, a first triggering mode. In the first triggering mode, when the terminal device needs to perform capability adjustment, the terminal device sends an indication of capability mode adjustment to the network device, which will be described below in different cases.

[0205] As shown in Figure 7 , a capability adjustment process schematic diagram provided by an embodiment of the present application. Figure 7 As shown in the flow, taking the network device as an access network device, the method comprises the following steps:

[0206] S701: The terminal device sends a third message to the access network device.

[0207] The third message can also be referred to as an on-demand capability adjustment request message or the like.

[0208] It should be noted that the terminal device can send the third message to the access network device in an RRC connected state or an RRC non-connected state. For example, when the terminal device is in an RRC inactive state, the terminal device can carry the third message through an RRC resume request message; when the terminal device is in an RRC idle state, the terminal device can carry the third message through an RRC setup request message.

[0209] The third message is used to indicate that the capability mode of the terminal device is adjusted to a first capability mode. The third message can include third indication information, and the third indication information indicates the first capability mode, which is the capability mode that the terminal device hopes to adopt.

[0210] It should be noted that the first capability mode is one of M capability modes selected by the terminal device, and the specific selection method is not limited by the present application.

[0211] The third message can also include other contents, for example, the third message can also include fourth indication information, and the fourth indication information indicates the adjustment reason or adjustment purpose of the first capability mode. The third message can also include fifth indication information, and the fifth indication information indicates the application duration of the first capability mode. The third message can also include a capability information set corresponding to the first capability mode.

[0212] S702: The access network device sends an RRC reconfiguration message to the terminal device.

[0213] After receiving the third message, the access network device can save the first capability mode and other information indicated in the third message, and perform RRC reconfiguration according to the first capability mode.

[0214] After performing the RRC reconfiguration, the access network device can perform resource scheduling according to the first capability mode indicated by the terminal device, and communicate with the terminal device according to the first capability mode.

[0215] Optionally, S703: the access network device sends third indication information to the core network device.

[0216] When the access network device determines that the application duration corresponding to the first capability mode is greater than the threshold, the third indication information can also be sent to the core network device, so that the core network device can update and save the first capability mode. When the terminal device performs handover, the access network device after the handover can obtain the current capability mode adopted by the terminal device from the core network device.

[0217] After the terminal device sends the third message, if the RRC reconfiguration message is not received within the preset time, the capability mode is actively adjusted to the first capability mode. Alternatively, after the terminal device receives the RRC reconfiguration message, if it is determined that the access network device does not perform RRC reconfiguration according to the first capability mode in the RRC reconfiguration, and the configured capability exceeds the capability of the terminal device, the terminal device can adjust the capability mode to the required first capability mode.

[0218] Optionally, the terminal device can also indicate to the access network device to adjust the capability mode to the first capability mode, for example, S704 can be performed.

[0219] Optionally, S704: the terminal device sends an RRC reconfiguration failure message to the access network device.

[0220] The RRC reconfiguration failure message is used to indicate that the capability mode is adjusted to the first capability mode, and the terminal device will communicate according to the adjusted first capability mode.

[0221] For example, the capability information set corresponding to the first capability mode is: the maximum carrier bandwidth is 20MHz, and the maximum aggregated carrier number is 4. According to the RRC reconfiguration message, the terminal device determines that the maximum carrier bandwidth configured by the access network device is 200MHz, and the maximum aggregated carrier number is 8. The terminal device can then send an RRC reconfiguration failure message.

[0222] As shown in FIG. 8, it is a capability adjustment process schematic diagram provided by an embodiment of the present application. Figure 8 As shown in FIG. 8, it is a capability adjustment process schematic diagram provided by an embodiment of the present application. Figure 8 As shown in FIG. 8, it is a capability adjustment process schematic diagram provided by an embodiment of the present application.

[0223] S801: The terminal device sends a third message to the core network device.

[0224] The third message can also be called a capability adjustment request message, and the specific content of the third message can refer to the description in S701, which will not be repeated here.

[0225] It should be noted that in S801, the terminal device can carry the third message through the NAS message. After receiving the third message, the core network device can also forward the third indication information in the third message to the access network device, and the specific process will not be described again.

[0226] Implementation mode two:

[0227] In the capability adjustment configuration process, the triggering mode of the capability adjustment can also be that the terminal device initiatively triggers the capability adjustment, and the network device confirms the capability adjustment, that is, a second triggering mode, which is described below in different cases.

[0228] As shown in Figure 9 , it is a capability adjustment process schematic diagram provided by an embodiment of the application. Figure 9 As shown in the process, taking the network device as the access network device, the method comprises the following steps:

[0229] S901: The terminal device sends a third message to the access network device.

[0230] The third message can also be called a capability adjustment request message, and the specific content of the third message can refer to the description in S701, which will not be described again here.

[0231] It should be noted that the terminal device can send the third message to the access network device in the RRC connected state or the RRC non-connected state.
