Description

Technical Field

[0002] In communication systems such as the Long Term Evolution (LTE) system and the New Radio (NR) system, terminal devices need to report their supported capability information to network devices (including access network devices and core network devices) during network registration. The network devices can perform operations such as resource scheduling based on the capability information of the terminal devices.

[0003] After registering with the network, a terminal device may need to change its capabilities in some scenarios. For example, the terminal device may experience overheating issues, reduce power consumption to save power, adjust capabilities due to hardware sharing requirements, change carrier frequencies due to severe interference, or require service requirements.

[0004] In the prior art, when the capability information of a terminal device changes, the terminal device needs to re-register with the network to update the capability information.

[0090] The technical solutions provided by the present application are further described below with reference to the accompanying drawings and examples. It should be understood that the system structures and business scenarios provided in the examples of the present application are mainly intended to explain some possible implementation methods of the technical solutions of the present application and should not be interpreted as limiting the uniqueness of the technical solutions of the present application. Those skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the examples of the present application are equally applicable to similar technical problems.

[0091] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as long term evolution (LTE) systems and NR systems, without limitation. It should be noted that the present application can be applied to independently deployed 5G or LTE systems, as well as to non-independently deployed 5G or LTE systems, such as dual-connectivity (DC) scenarios.

[0092] In the embodiments of the present application, a terminal device may be a device with wireless transceiver capabilities or a chip that can be installed in any device. It may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. The terminal device in the embodiments of the present application may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, etc.

[0093] The access network equipment can be a next generation base station (gNB) in the NR system, an evolutionary base station (eNB) in the LTE system, etc.

[0094] Figure 1 This is a schematic diagram of a network architecture applicable to this application. Figure 1 As shown, the terminal device can access the access network device to obtain services of the external network (such as 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.

[0095] In embodiments of the present application, the capability of a terminal device may refer to a static capability determined based on factors such as the hardware and / or software configuration of the terminal device, and is used to indicate whether the terminal device supports a certain feature or feature set. For example, if the maximum bandwidth supported by the RF channel of the terminal device is 100 MHz, then the maximum bandwidth supported by the terminal device is 100 MHz.

[0096] The capabilities of a terminal device may also refer to dynamically configured capabilities. For example, the capabilities of a terminal may be dynamically configured based on factors such as the working environment. For example, after a terminal device is registered in the network, it may be desirable to change capability information in some scenarios. For example, the terminal device may have an overheating problem; or the terminal device may reduce power consumption to save power; or the terminal device may need to adjust its capabilities due to hardware sharing requirements; or the terminal device may need to change its carrier frequency due to severe interference problems; or the terminal device may need to change its capabilities due to business needs. The network device may reduce the capabilities of the terminal device through high-layer signaling, media access control (MAC) layer signaling, or physical (PHY) layer signaling.

[0097] In the embodiments of the present application, the interaction between a network device and a terminal device is taken as an example for explanation. The operations performed by the network device can also be performed by a chip or module inside the network device, and the operations performed by the terminal device can also be performed by a chip or module inside the terminal device.

[0098] Combined with the previous description, such as Figure 2 FIGURE 1 is a flow chart of a communication method provided by an embodiment of the present application. Figure 2 , the method comprising:

[0099] S201: The terminal device determines the indication information.

[0100] In the embodiment of the present application, the indication information may be carried in the capability adjustment request message or the auxiliary information, or the indication information may also refer to the auxiliary information.

[0101] The capability adjustment request message is used to request adjustment of the capabilities of the terminal device. Auxiliary information may also be referred to as UE auxiliary information, and is hereinafter referred to as auxiliary information. The terminal device can report desired configuration parameters (such as the first parameter set below) to the network device through the auxiliary information. The network device can refer to the auxiliary information reported by the terminal device to perform RRC reconfiguration, thereby avoiding the terminal device from updating its capabilities through the registration process, reducing latency and signaling overhead.

[0102] The above are just examples, and the indication information can also be carried through other messages or information, which is not limited in the embodiments of the present application.

[0103] The indication information includes a first parameter set, and the first parameter set is used by the network device to adjust the configuration parameters of the terminal device based on the first parameter set. For example, the first parameter set may include one or more of the following: in-device coexistence (IDC) auxiliary information; discontinuous reception (DRX) preference parameter; maximum aggregate bandwidth preference parameter; maximum number of carriers preference parameter; maximum multiple input multioutput (MIMO) layer number preference parameter; minimum scheduling offset parameter; radio resource control (RRC) state preference parameter; sidelink auxiliary information, etc. The above are just examples, and the first parameter set may also include other content, which will not be explained one by one here.

[0104] The indication information may further include at least one of the first information or the second information. The first information is used to indicate the urgency, importance, or urgency of data transmission with the network device according to the first parameter set, or to indicate the urgency, importance, or urgency of reconfiguration according to the first parameter set.

[0105] This application does not limit how the terminal device determines the degree of urgency, importance, or urgency. For example, the terminal device may determine the degree of urgency / urgency / importance based on at least one of the following: the terminal device's temperature, battery level, carrier interference, radio frequency capacity utilization, baseband resource utilization, or service type.

[0106] There may be multiple specific implementations of the first information. For example, in the first embodiment, the first information is an adjustment level, where a higher adjustment level indicates a higher urgency, importance, or urgency of transmitting data or changing the configuration of the terminal device according to the first parameter set.

[0107] For example, four adjustment levels are predefined: Level 0 to Level 3, where Level 0 indicates that the adjustment urgency / urgentness / importance of performing data transmission or changing the configuration of the terminal device according to the first parameter set is the lowest, and Level 3 indicates that the adjustment urgency / urgentness / importance of performing data transmission or changing the configuration of the terminal device according to the first parameter set is the highest. In this case, the first information may include 2 bits, and the adjustment level indicated by the first information may be shown in Table 1.

[0108] Table 1

[0109] First Information Adjustment level 00 Level 0 01 Level 1 10 Level 2 11 Level 3

[0110] In the second method, the first information is an adjustment factor, for example, the adjustment factor ranges from 0 to 1. The larger the adjustment factor, the higher the urgency / urgentness / importance. For example, when the temperature of the terminal device rises slowly, or the battery of the terminal device decreases slowly, or the carrier interference level is low, or the radio frequency capability occupancy is low, or the baseband resource occupancy is low, or the service delay is sensitive, the urgency / urgency / importance can be considered low, and the value of the first information (adjustment factor) can be small, such as 0.2; and when the temperature of the terminal device rises quickly, or the UE battery decreases quickly, or the carrier interference level is high, or the radio frequency capability occupancy is high, or the baseband resource occupancy is high, or the service delay is not sensitive, the value of the first information (adjustment factor) can be large, such as 0.8.

[0111] In an embodiment of the present application, multiple parameters in the first parameter set can correspond to an adjustment level / adjustment factor. For example, if the first parameter set includes one or more preference parameters for energy saving, an adjustment level / adjustment factor is defined for energy saving, and all preference parameters related to energy saving correspond to the adjustment level / adjustment factor.

[0112] In addition, an adjustment level / adjustment factor may be reported for each preference parameter in the first parameter set. For example, corresponding adjustment levels / adjustment factors may be defined for the DRX preference parameter, the maximum bandwidth preference parameter, the maximum carrier preference parameter, and the maximum MIMO layer preference parameter. The network device may reconfigure the parameters based on the adjustment level / adjustment factor corresponding to each parameter.

[0113] In a third approach, the degree of urgency or importance can be the probability of executing the first action or triggering the first event. In this case, the first information can be an adjustment probability, indicating the probability that the terminal device will execute the first action or trigger the first event when the network device does not transmit data with the terminal device in accordance with the first parameter set; or indicating the probability that the terminal device will execute the first action or trigger the first event when the network device does not refer to the first parameter set for reconfiguration, or when the network device reconfigures beyond the configuration of the first parameter set. The adjustment probability can range from 0% to 100%. The greater the probability, the higher the urgency / urgency / importance of the capability adjustment, and the greater the possibility that the terminal device will execute the first action or trigger the first event.

[0114] The specific content of the first action and the first event will be described later and will not be repeated here.

[0115] In an embodiment of the present application, the second information is used to indicate that a first action is executed or a first event is triggered when a rejection message for the indication information is received or when no response information for the indication information is received.

[0116] The response information may be an RRC reconfiguration message sent by the network device after receiving the indication information, indicating that data is transmitted with the terminal device according to the first parameter set, or reconfiguration is performed with reference to the first parameter set.

[0117] The terminal device may start timing when sending the indication information, and the timing duration is a preset duration. If a response message to the indication message is received within the preset duration, and the response message indicates that data should be transmitted with the terminal device according to the first parameter set, or reconfigured with reference to the first parameter set, the terminal device may stop timing. If no response message is received within the preset duration, the first action is executed or the first event is triggered. The preset duration can be reported by the terminal device to the network device, configured by the network device, or determined by a predefined method, and is not limited in this application.

[0118] The rejection message is used to instruct the network device to refuse to transmit data with the terminal device according to the first parameter set, or to instruct the network device not to reconfigure with reference to the first parameter set.

[0119] In this embodiment of the present application, the first action includes at least one of the following:

[0120] 1. Report radio link failure. In the DC scenario, when the terminal device is in the master cell group (MCG), the terminal device can report the radio link failure of the MCG to the master node (MN); when the UE is in the secondary cell group (SCG), the terminal device reports the radio link failure of the SCG to the MN.

[0121] 2. Failure to report to SCG;

[0122] 3. Request RRC connection reestablishment: The terminal device can request RRC connection reestablishment from the network device;

[0123] 4. Perform mobility registration update, that is, re-register to the network, and the registration type is "mobile registration update";

[0124] 5. Feedback NACK, including but not limited to feedback of an automatic repeat request (ARQ) negative acknowledgement (NACK) at the radio link control (RLC) layer or feedback of a hybrid automatic repeat request (HARQ) NACK at the medium access control (MAC) layer. Feedback NACK may mean that when the terminal device receives data at the RLC layer, it feeds back an ARQ NACK regardless of whether the data is received correctly; when the terminal device receives data at the MAC layer, it feeds back a HARQ NACK regardless of whether the data is received correctly.

[0125] 6. Increased probability of NACK feedback; including but not limited to increased probability of ARQ NACK feedback at the RLC layer or increased probability of HARQ NACK feedback at the MAC layer. The increased probability of NACK feedback may mean that when the terminal device receives data at the RLC layer, if the data is correctly received, there is a certain probability of ARQ NACK feedback; when the terminal device receives data at the MAC layer, if the data is correctly received, there is a certain probability of HARQ NACK feedback;

[0126] 7. Deactivate the secondary cell (Scell) or SCG to which the terminal device is connected;

[0127] 8. Release the SCell or SCG to which the terminal device is connected;

[0128] 9. Perform conditional switching.

[0129] In this embodiment of the present application, the first event includes at least one of the following:

[0130] Radio link failure; SCG failure; RRC connection reestablishment; mobility registration update; NACK feedback; increased probability of NACK feedback; deactivation of the SCell or SCG to which the terminal device is connected; release of the SCell or SCG to which the terminal device is connected; conditional switching.

[0131] It should be noted that in the embodiments of the present application, the terminal device may first trigger the first event and then execute the first action; or the terminal device may directly execute the first action; or the terminal device may trigger the first event but not necessarily execute the first action.

[0132] It should be noted that, when the indication information is auxiliary information, a message field may be added to the auxiliary information to carry the first information or the second information.

[0133] 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.

[0134] S202: The terminal device sends instruction information to the network device.

[0135] S203: The network device receives instruction information from the terminal device.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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:

[0142] Optionally, S301: the terminal device sends a second message to the network device, where the second message includes second indication information.

[0143] The name of the second message is not limited, for example, it can be a capability adjustment configuration message.

[0144] The second indication information indicates N capability modes, where one capability mode among the N capability modes corresponds to a set of capability information, and N is an integer greater than 0. The capability information set may include at least one of the following capabilities: wireless capability of the terminal device; core network capability of the terminal device; and positioning capability of the terminal device.

[0145] It should be noted that the second message may be a capability adjustment configuration message sent by the terminal device to the network device after establishing a connection with the network device, indicating to the network one or more capability modes that the UE may adjust. One capability mode corresponds to a set of UE capability information. The capability information here may include UE wireless capabilities and / or UE core network capabilities and / or UE positioning capabilities. The message may be sent to the network device via an RRC message or a non-access stratum (NAS) message. Exemplarily, the terminal device may 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.

[0146] Exemplarily, the second indication information may also be UE capability information (UE capability information), or the second indication information may also be carried in the UE capability information. The terminal device may send the UE capability information to the terminal device after receiving a UE capability enquiry (UE capability enquiry) message from the network device.

[0147] In an embodiment of the present application, the second message may include N sets of capability information sets or may not include N sets of capability information sets. When the second message does not include N sets of capability information sets, a correspondence between capability modes and capability information sets may be pre-established. The correspondence between capability modes and capability information sets is known to both the terminal device and the network device, and the network device may thereby determine the corresponding capability information set based on the capability mode.

[0148] For example, the second indication information is a bitmap, and the reported capability mode can be represented 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, which indicate capability mode 0 to 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, if the second indication information is 1011, it means that the capability modes indicated by the second indication information are capability mode 0, capability mode 2, and capability mode 3.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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:

[0154] Capability mode applicable to terminal devices when the temperature is too high or overheating; capability mode applicable to energy saving; capability mode applicable to NR and wireless local area network (WLAN) capability sharing; capability mode applicable to multiple subscriber identity module (SIM) card capability sharing; capability mode applicable to vehicle to everything (V2X) capability sharing; capability mode applicable to ultra-high reliability and low latency (URLLC) services; capability mode applicable to reduced capability (REDCAP) services.

[0155] The terminal device may explicitly or implicitly indicate the reason or purpose for adjusting each capability mode. When the terminal device indicates explicitly, the second message may carry adjustment indication information, indicating the reason or purpose for adjusting each capability mode. When the terminal device indicates implicitly, the reason or purpose for adjusting the capability mode may be pre-agreed.

[0156] In the embodiment of the present application, the capability mode may also correspond to other information, for example, each capability mode may correspond to a different peak rate level, etc., which will not be described in detail.

[0157] Optionally, S302: the network device receives a second message from the terminal device.

[0158] S303: The network device sends a first message to the terminal device.

[0159] The name of the first message is not limited, for example, it can be a capability adjustment configuration confirmation message.

[0160] The first message includes first indication information. The first message or the first indication information may indicate M capability modes. For example, the first message or the first indication information may include M mode identifiers, and one mode identifier corresponds to one capability mode. The first indication information may also be used to indicate permission to request adjustment of the capability of the terminal device to one of the M capability modes; M is an integer greater than 0. Herein, permission to request adjustment of the capability of the terminal device to one of the M capability modes may refer to permission of the terminal device to send an indication message or a request message to the network device; the indication message or the request message is used to indicate adjustment of the capability mode of the terminal device to one of the M capability modes.

[0161] It should be noted that if the terminal device sends an indication message, the indication message may indicate that the terminal device will perform data transmission or work in accordance with a capability mode indicated in the indication message, and the capability mode belongs to M capability modes. The capability mode may also be carried in the indication message. The terminal device does not need to wait for feedback from the network device. The terminal device believes that the network device will be configured or reconfigured in accordance with the capability mode indicated in the indication message. After reconfiguration, the terminal device performs data transmission or work in accordance with a capability mode indicated in the indication message. It should be noted that the feedback here refers to feedback on the content of the indication message, and does not refer to the ACK / NACK feedback in the normal data transmission process.

[0162] If the terminal device sends a request message, the request message may indicate a request for data transmission or operation to be performed in accordance with the capability mode indicated in the request message. The terminal device needs to wait for feedback from the network device. When the terminal device determines based on the feedback that the network device is configured in accordance with the capability mode indicated in the request message, it then performs data transmission or operation in accordance with the capability mode indicated in the request message.

[0163] In an embodiment of the present application, in one possible implementation, when a terminal device indicates N capability modes via a second message, the M capability modes may be selected by the network device from the N capability modes reported by the terminal device. The specific selection method is not limited by this application. For example, if the terminal device reports that the capability modes it wishes to adjust are capability mode 1, capability mode 2, and capability mode 3, and the network device allows the terminal device to adjust to capability mode 1 and capability mode 3, then capability mode 1 and capability mode 3 are indicated via the first indication information.

[0164] In another possible implementation, the M capability modes may be predefined by the protocol or determined autonomously by the network device. There may be other ways to determine the M capability modes, which will not be described one by one here.

[0165] In this implementation, the first message may be a broadcast message or a multicast message. The network device may indicate M capability modes to all terminal devices connected to the network device via a broadcast message or a multicast message, that is, to indicate M capability modes to multiple terminal devices simultaneously.

[0166] The network device can also indicate M capability modes to specific types of terminal devices through broadcast messages or multicast messages. Specific types of terminal devices include but are not limited to reduced capability (REDCAP) terminal devices, ultra-high reliability and low latency (URLLC) terminal devices, and vehicle to everything (V2X) terminal devices.

[0167] Of course, the M capability modes indicated by the first message may also be for only one terminal device, and this embodiment of the present application is not limited to this.

[0168] The network device can configure a corresponding capability adjustment triggering method for each capability mode. In this case, the second message may also include trigger information; the trigger information indicates the capability adjustment triggering methods for the M capability modes. In this embodiment of the present application, the capability adjustment triggering methods may include at least one of the following: a first triggering method, in which capability adjustment is triggered by the terminal device; in this method, when the terminal device requires capability adjustment, it sends a capability mode adjustment indication to the network device. A second triggering method, in which the terminal device requests capability adjustment, and the network device confirms the capability adjustment. In this method, when capability adjustment is required, the terminal device sends a capability mode adjustment indication to the network device. If an on-demand capability adjustment confirmation is received from the network device within a preset waiting time, the capability mode adjustment is determined to be successful. The preset waiting time is configured by the network device or set by the terminal device. A third triggering method, in which capability adjustment is triggered by the network device, in which case the network device triggers whether to perform capability adjustment. When the network device requires capability adjustment of the terminal device due to service needs, it sends an on-demand capability adjustment indication to the terminal device, indicating the adjusted capability mode.

[0169] The network device can also configure a corresponding capability recovery method for each capability mode, and the second message can also include recovery information in this case; the recovery information indicates the capability recovery method of M capability modes. In an embodiment of the present application, the capability recovery method may include at least one of the following: a first recovery method, which refers to restoring the capability before the capability adjustment based on a timing duration; in this method, 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 the timer, and after the timer times out, the terminal device restores to the original capability before the capability adjustment. The timing duration of the timer is the application duration corresponding to 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 adjusting the capability.

[0170] The second restoration method involves restoring capabilities prior to the capability adjustment, triggered by the terminal device. In this method, the terminal device sends a capability restoration instruction to the network device, instructing the terminal device to restore its original capabilities prior to the capability adjustment. For capability adjustments triggered by the terminal device (either the first or second triggering method), the network device can configure whether to enable capability restoration triggered by the terminal device.

[0171] The third restoration mode is to restore the capacity before the capacity adjustment triggered by the network device. For the capacity adjustment triggered by the network device (the third trigger mode), the network device can send a capacity restoration instruction to the terminal device to instruct the terminal device to restore the original capacity.

[0172] It should be noted that when the network device is an access network device, for capability recovery triggered by the terminal and capability recovery triggered by the access network device, if the access network device sends the adjusted capability mode of the terminal device to the core network device when the capability of the terminal device is restored, the access network device may also indicate the capability of the terminal device after capability recovery to the core network device.

[0173] S304: The terminal device receives a first message from the network device.

[0174] It should be noted that Figure 3 The network equipment in the process can refer to access network equipment or core equipment. The following describes the different situations.

[0175] Specifically, take the network device as an access network device as an example, Figure 4 As shown, this is a schematic diagram of a capability adjustment configuration process provided by this application.

[0176] S401: The terminal device sends a capability adjustment configuration message to the access network device.

[0177] The capability adjustment configuration message includes the second indication information, and the capability adjustment configuration message may refer to the aforementioned second message.

[0178] In one possible implementation, the capability adjustment configuration message is an RRC message, and the terminal device can send the capability adjustment configuration message directly to the access network device; in another possible implementation, 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, and the core network device forwards the capability adjustment configuration message to the access network device.

[0179] Among them, the specific content of the N groups of capability information sets included in the second message is not limited. For example, the capability information set may include the wireless capabilities of the terminal device, including radio frequency (RF) capabilities, measurement and mobility capabilities, layer 2 capabilities, etc.

[0180] S402: The access network device sends a capability adjustment configuration confirmation message to the terminal device.

[0181] The capability adjustment configuration confirmation message includes the first indication information, and the capability adjustment configuration confirmation message may refer to the previous first message.

[0182] S403: The access network device sends a capability mode configuration message to the core network device.

[0183] The capability mode configuration message may indicate M capability modes.

[0184] Take the network equipment as the core network equipment as an example, Figure 5 As shown, this is a schematic diagram of a capability adjustment configuration process provided by this application.

[0185] S501: The terminal device sends a capability adjustment configuration message to the core network device.

[0186] The capability adjustment configuration message includes the second indication information, and the capability adjustment configuration message may refer to the aforementioned second message.

[0187] There is no restriction on the specific content of the N groups of capability information sets included in the second message. For example, the capability information set includes the wireless capabilities and core network capabilities of the terminal device.

[0188] In one possible implementation, 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. When the access network device receives the NAS message from the terminal device, it transparently forwards it to the core network device.

[0189] In another possible implementation, the capability adjustment configuration message is an RRC message. 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. In this implementation.

[0190] S502: The core network device sends a capability adjustment configuration confirmation message to the terminal device.

[0191] The capability adjustment configuration confirmation message includes the first indication information, and the capability adjustment configuration confirmation message may refer to the previous first message.

[0192] It should be noted that the capability adjustment configuration confirmation message may be a NAS message, and the core network device may send the capability adjustment configuration confirmation message to the terminal device through the access network device.

[0193] S503: The core network device may also send a capability adjustment configuration assistance message to the access network device. The capability adjustment configuration assistance message indicates M capability modes.

[0194] These M capability modes are candidate capability modes when the terminal device performs capability adjustment, and are M capability modes that the terminal device is allowed to adjust.

[0195] Take the network device as an access network device as an example, Figure 6 As shown, this is a schematic diagram of a capability adjustment configuration process provided by this application.

[0196] S601: The terminal device sends a capability adjustment configuration message to the core network device. The capability adjustment configuration message may refer to the second message mentioned above.

[0197] There is no limitation on the specific content of the N sets of capability information included in the second message. For example, the capability information set includes core network-related capabilities and / or positioning capabilities.

[0198] In this scenario, the capability adjustment configuration message may be a NAS message, and the terminal device may directly send the capability adjustment configuration message to the core network device.

[0199] S602: The core network device sends a capability adjustment configuration confirmation message to the terminal device. The capability adjustment configuration confirmation message may refer to the first message mentioned above.

[0200] Through the previous process, the terminal device can pre-negotiate with the network device to determine that the terminal device can select a capability mode from M capability modes for capability adjustment, thereby increasing the autonomy of the terminal device in capability adjustment. At the same time, since the terminal device has reported the capability mode that may be adjusted to the network device in advance, when the terminal capability mode changes, the complexity of the network device scheduling multi-capability mode terminal devices can be reduced.

[0201] In an embodiment of the present application, after the terminal device and the network device pre-negotiate M capability modes, the terminal device or the network device may trigger adjustment of the capabilities of the terminal device, wherein the network device may be an access network device or a core network device, the access network device may refer to a gNB or an eNB, etc., and the core network device may refer to an access and mobility management function (AMF) network element or a location management function (LMF) network element, etc., which are described below in different situations.

[0202] Implementation method 1:

[0203] In the capability adjustment configuration process, the capability adjustment can be triggered by the terminal device actively triggering the capability adjustment, i.e., the first triggering mode. In the first triggering mode, when the terminal device needs to adjust the capability, it sends an instruction to adjust the capability mode to the network device. The following describes different situations.

[0204] like Figure 7 The figure shows a schematic diagram of a capability adjustment process provided in an embodiment of the present application. Figure 7 In the process shown, taking the network device as an access network device as an example, the method includes:

[0205] S701: The terminal device sends a third message to the access network device.

[0206] The third message may also be called an on-demand capability adjustment request message or the like.

[0207] 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. For example, when the terminal device is in the RRC inactive state, the third message can be carried in the RRC recovery request message; when the terminal device is in the RRC idle state, the third message can be carried in the RRC establishment request message.

[0208] The third message is used to instruct the terminal device to adjust its capability mode to the first capability mode. The third message may include third indication information, the third indication information indicating the first capability mode, and the first capability mode is the capability mode that the terminal device wants to adopt.

[0209] It should be noted that the first capability mode is a capability mode selected by the terminal device from M capability modes, and this application does not limit the specific selection method.

[0210] The third message may also include other content, for example, fourth indication information indicating the reason or purpose for adjusting the first capability mode. The third message may also include fifth indication information indicating the application duration of the first capability mode. The third message may also include a capability information set corresponding to the first capability mode.

[0211] S702: The access network device sends an RRC reconfiguration message to the terminal device.

[0212] After receiving the third message, the access network device may save information such as the first capability mode indicated in the third message, and perform RRC reconfiguration according to the first capability mode.

[0213] After 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.

[0214] Optionally, S703: the access network device sends third indication information to the core network device.

[0215] When the access network device determines that the application duration corresponding to the first capability mode is greater than a threshold, it may also send third indication information to the core network device, so that the core network device can update and save the first capability mode. When the terminal device switches, the access network device after the switch can obtain the capability mode currently used by the terminal device from the core network device.

[0216] If the terminal device does not receive an RRC reconfiguration message within a preset time after sending the third message, the terminal device proactively adjusts the capability mode to the first capability mode. Alternatively, after receiving the RRC reconfiguration message, if the terminal device determines that the access network device did not perform RRC reconfiguration in accordance with the first capability mode during RRC reconfiguration, and the configured capability exceeds the capability of the terminal device, the terminal device may adjust the capability mode to the required first capability mode.

[0217] Optionally, the terminal device may further instruct the access network device to adjust the capability mode to the first capability mode, for example, S704 may be executed.

[0218] Optionally, S704: the terminal device sends an RRC reconfiguration failure message to the access network device.

[0219] 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.

[0220] For example, the capability information set corresponding to the first capability mode is: the maximum carrier bandwidth is 20 MHz, and the maximum number of aggregated carriers is 4. The terminal device determines, based on the RRC reconfiguration message, that the maximum carrier bandwidth configured for the access network device is 200 MHz and the maximum number of aggregated carriers is 8, and the terminal device can then send an RRC reconfiguration failure message.

[0221] like Figure 8 The figure shows a schematic diagram of a capability adjustment process provided in an embodiment of the present application. Figure 8 In the process shown, taking the network device as a core network device as an example, the method includes:

[0222] S801: The terminal device sends a third message to the core network device.

[0223] The third message may also be called an on-demand capability adjustment request message or the like. For the specific content of the third message, reference may be made to the description in S701 and will not be repeated here.

[0224] It should be noted that in S801, the terminal device may carry the third message via a NAS message. After receiving the third message, the core network device may also forward the third indication information in the third message to the access network device. The specific process will not be repeated here.

[0225] Implementation method 2:

[0226] In the capability adjustment configuration process, the capability adjustment may also be triggered by the terminal device actively triggering the capability adjustment, and the network device confirming the capability adjustment, i.e., the second triggering mode, which is described below in different situations.

[0227] like Figure 9 The figure shows a schematic diagram of a capability adjustment process provided in an embodiment of the present application. Figure 9 In the process shown, taking the network device as an access network device as an example, the method includes:

[0228] S901: The terminal device sends a third message to the access network device.

[0229] The third message may also be called an on-demand capability adjustment request message or the like. For the specific content of the third message, reference may be made to the description in S701 and will not be repeated here.

[0230] 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. For example, when the terminal device is in the RRC inactive state, the third message can be carried in the RRC recovery request message; when the terminal device is in the RRC idle state, the third message can be carried in the RRC establishment request message.

[0231] S902: The access network device sends a fourth message to the terminal device.

[0232] The fourth message may also be called an on-demand capability adjustment confirmation message or the like, and the fourth message is used to indicate confirmation of adjusting the capability mode of the terminal device to the first capability mode.

[0233] It should be noted that when the third message is carried through the RRC recovery request message, the fourth message can be carried through the RRC recovery confirmation message; when the third message is carried through the RRC establishment request message, the fourth message can be carried through the RRC establishment message.

[0234] The fourth message may also indicate a recovery method for recovering the capabilities of the terminal device before the capability adjustment. The recovery methods include but are not limited to the first recovery method to the third recovery method described above, and the specific contents will not be repeated here.

[0235] Optionally, S903: the access network device sends third indication information to the core network device.

[0236] When the access network device determines that the application duration corresponding to the first capability mode is greater than the threshold, it may also send the third indication information in the third message to the core network device, so that the core network device can update and save the first capability mode. When the terminal device switches, the access network device after the switch can obtain the capability mode currently used by the terminal device from the core network device.

[0237] Optionally, S904: the terminal device sends an RRC reconfiguration failure message to the access network device.

[0238] After the terminal device receives the RRC reconfiguration message, if it is determined that the access network device did not perform RRC reconfiguration in accordance with the first capability mode during 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 for communication.

The specific selection method is not limited in this application.

[0258] The capability adjustment indication message may further indicate the reason or purpose for adjusting the second capability mode, and may further indicate information such as the application duration of the second capability mode.

[0259] It should be noted that the access network equipment can adjust the capabilities of the terminal equipment based on business needs and other purposes, and the embodiments of the present application are not limited thereto.

[0260] S1102: The access network device sends an RRC reconfiguration message to the terminal device.

[0261] The access network device may perform RRC reconfiguration according to the second capability mode, thereby sending an RRC reconfiguration message.

[0263] Optionally, S1103: the access network device sends capability mode indication information to the core network device, where the capability mode indication information indicates the second capability mode.
