For example, the UE can act as a scheduling entity, providing sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D) communication. For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0044] The network device in this application embodiment can be a device for communicating with terminal devices. The network device may also include an access network device. The access network device can provide communication coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The access network device can also be called a wireless access network device or a base station, etc. In this application embodiment, the access network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

The embodiments of this application do not limit the specific technologies or device forms used in the access network equipment.

[0045] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0046] Wireless communication systems involve communication equipment that can include not only access network equipment and terminal equipment, but also core network elements. Core network elements can be implemented through devices; that is, core network elements are core network devices. It is understandable that core network devices can also be a type of network device.

[0047] The core network elements in this application embodiment may include network elements that process and forward user signaling and data. For example, core network equipment may include core access and mobility management function (AMF), session management function (SMF), user plane gateway, location management function (LMF), and other core network equipment. The user plane gateway may be a server with functions such as mobility management, routing, and forwarding of user plane data, generally located on the network side, such as a serving gateway (SGW), packet data network gateway (PGW), or user plane function (UPF). Of course, the core network may also include other network elements, which are not listed here.

[0048] In some deployments, the network device in this application embodiment may refer to a CU or a DU, or the network device may include both a CU and a DU. The gNB may also include an AAU.

[0049] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0050] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0051] Wireless communication based on artificial intelligence (AI)

[0052] AI / machine learning (ML) based solutions are increasingly being used in wireless communication systems. Examples are provided below using Figures 2A-2D.

[0053] As shown in Figure 2A, the channel state information (CSI) feedback problem can be solved using AI. In Figure 2A, by introducing an AI encoder and an AI decoder, AI-based CSI information compression and feedback can be achieved.

[0054] As shown in Figure 2B, the channel estimation problem can be solved using AI. In Figure 2B, the AI ​​channel estimator enables high-performance estimation of a given channel.

[0055] As shown in Figure 2C, the positioning problem can be solved using AI. In Figure 2C, a high-precision positioning result can be obtained through an AI-based positioning algorithm that relies on positioning channel information.

[0056] As shown in Figure 2D, beam management problems can be solved using AI. In Figure 2D, an AI-based beam management algorithm can obtain optimal beam information, more refined beam information, or predictions of beam information at future moments based on known beam information.

[0057] It should be noted that AI-based wireless communication solutions are not limited to the examples mentioned above. That is, AI solutions can be designed for other problems. Alternatively, even for the same problem, there can be numerous other different AI solutions. Or, even for the same AI solution, different implementing entities can have different deployment and optimization schemes.

[0058] Cell handover

[0059] In wireless communication systems (such as LTE or NR systems), when a terminal device using network services moves from one cell to another, or due to adjustments in wireless transmission load, activation maintenance, equipment failure, or other reasons, in order to maintain the continuity of communication and the quality of service for the terminal device, the system needs to transfer the communication link between the terminal device and the original cell to a new cell, i.e., perform a cell handover process. The cell providing services to the terminal device before the handover can be called the "serving cell" or "source cell," and the cell providing services to the terminal device after the handover can be called the "target cell."

[0060] It should be noted that, in the embodiments of this application, the serving cell corresponds to the source network device (e.g., source base station, source gNB) or the serving network device (e.g., serving base station, serving gNB), and the target cell corresponds to the target network device (e.g., target base station, target gNB).

[0061] It should be understood that in the embodiments of this application, the source cell and the target cell may correspond to the same network device (such as a base station), or the source cell and the target cell may correspond to different network devices. In other words, in some embodiments, the source network device and the target network device may refer to the same network device. The embodiments of this application are not limited in this respect.

[0062] The cell handover process will be briefly described below with reference to Figure 3. As shown in Figure 3, the cell handover process may include steps 1 to 4.

[0063] In step 1, the source network device sends a handover request message to the target network device.

[0064] In step 2, the target network device can perform admission control to provide new RRC configuration information. The target network device sends a handover request acknowledgment to the source network device.

[0065] In step 3, the source network device sends a radio resource control (RRC) configuration message to the terminal device.

[0066] In step 4, the terminal device sends an RRC configuration complete message to the target network device, thereby enabling the terminal device and the target network device to establish an RRC connection.

[0067] Conditional handover (CHO)

[0068] The primary goal of conditional handover is to improve the reliability and robustness of user handover. The core idea of ​​conditional handover is to pre-configure the handover command content for the terminal device. When specific conditions are met, the terminal device can autonomously execute the configuration in the handover command and directly initiate handover access to the target cell that meets the conditions.

[0069] Handover can be implemented based on a first trigger condition and a second trigger condition. The first trigger condition can trigger the terminal device to report measurements and correspondingly trigger the network equipment to prepare for handover. The second trigger condition can trigger the terminal device to initiate access to the target cell to complete the handover.

[0070] The following is a brief introduction to the condition switching process with reference to Figure 4.

[0071] In step 1, the terminal device sends a measurement report to the serving network device. The measurement report may include a "low" threshold. The "low" threshold may be the trigger threshold of the first triggering condition.

[0072] Source network devices can make handover decisions (HO decisions) based on early reports.

[0073] In step 2, the source network device can send an early handover request (HO request) to the target network device.

[0074] The target network device can accept the switch and build an RRC configuration.

[0075] The early reporting and early handover request steps performed by the network device can be understood as the network device preparing for handover.

[0076] In step 3, the target network device may send a handover confirmation (HO Ack) to the serving network device. The handover confirmation may include RRC configuration.

[0077] In step 4, the serving network device sends a conditional switching command (HO command). The conditional switching command may include a "high" threshold.

[0078] On the terminal device side, if the measurements fulfill the handover condition (HO condition), the terminal device can trigger a pending conditional handover (UE triggers pending cond.HO). The handover condition can be the second triggering condition mentioned above.

[0079] In step 5, the terminal device initiates synchronization and random access to the target network device.

[0080] In step 6, the terminal device may send a handover confirmation (HO confirm) message to the target network device.

[0081] In step 7, the target network device can send a handover completed (HO completed) message to the serving network device.

[0082] For mobility scenarios, this application proposes an improved technical solution.

[0083] Figure 5 is a schematic flowchart of a wireless communication method provided in an embodiment of this application. The method shown in Figure 5 can be executed by one or more of a first network device, a second network device, and a terminal device.

[0084] In some embodiments, the first network device may correspond to a first cell. The first cell may include a target cell, that is, the first network device may include a target network device.

[0085] It should be noted that the target cell may include one or more of the following: the target cell for handover, the target cell for access, the target cell for entry through re-establishment, the target cell for entry through cell reselection, etc.

[0086] In some embodiments, the second network device may correspond to a second cell. The second cell may include a serving cell, that is, the second network device may include a serving network device.

[0087] It should be noted that, in this application, the serving cell may include the current serving cell and / or the historical serving cell.

[0088] The method shown in Figure 5 may include step S510.

[0089] In step S510, the first network device receives the first information.

[0090] Optionally, the first information may be sent by the terminal device. That is, step S510 may include step S511, in which the terminal device sends the first information to the first network device.

[0091] Optionally, the first information may be sent by the second network device. That is, step S510 may include step S512, in which the second network device sends the first information to the first network device.

[0092] The first information can be used to indicate one or more of the following information of the terminal device: first capability information, first function information, and first model information. These will be explained below.

[0093] The first capability information can be used to indicate the capabilities that the terminal device can support. Optionally, this capability can be related to AI processing capabilities or AI capabilities. In other words, the first capability information can be related to the AI ​​capabilities or AI processing capabilities of the terminal device. For example, the first capability information may include one or more of the following: models that the terminal device can support, functions that the terminal device can support, use cases that the terminal device can support, model structures that the terminal device can support, etc.

[0094] First functional information can be used to indicate information related to a function of a terminal device. In some cases, a function is also referred to as a use case. For example, first functional information can also be referred to as first use case information.

[0095] The first model information can be used to indicate information related to the model.

[0096] It should be noted that the functions, models, use cases, and model structures in this application may be related to AI / ML. For example, functions may include those implemented based on AI / ML. Similarly, functions may include AI / ML-based solutions or applications. Furthermore, models may be AI / ML models. Optionally, AI / ML may include one or more of the following: AI / ML-based CSI feedback and prediction; AI / ML-based channel estimation; AI / ML-based localization; AI / ML-based beam management and beam prediction; AI / ML-based modulation and demodulation; AI / ML-based data detection; AI / ML-based transmission feedback; AI / ML-based channel coding and decoding; AI / ML-based semantic communication; AI / ML-based source-channel joint coding; AI / ML-based mobility management; AI / ML-based measurement prediction; AI / ML-based target cell prediction; AI / ML-based link monitoring; and AI / ML-based resource management, etc.

[0097] Based on the first information, the first network device can clearly know the capabilities of the newly connected / accessed terminal device, and / or the usage, deployment, and loading status of the model / function, which is conducive to the first network device performing the corresponding operation.

[0098] In some embodiments, the first information may be used to determine the model and / or functions used by the terminal device in the target cell. The target cell may be a cell that the terminal device has newly joined / accessed.

[0099] In mobility scenarios, models and functions (e.g., AI / ML related) that a terminal device can use or has already used within a cell (e.g., the serving cell) may or may not continue to be used when the terminal device enters another cell (e.g., the target cell). For example, regarding models, when the terminal device enters another cell, it may continue to use the model (the model's structure and coefficients (or parameters) remain unchanged), or it may continue to use the model's structure and update the model's coefficients (the model's structure remains unchanged, but the coefficients are updated adaptively), or it may no longer be able to use the model (a new model is loaded). Similarly, regarding functions, when the terminal device enters another cell, it may continue to use the function, or it may no longer be able to use the function.

[0100] It should be noted that continuing to use a model (including its structure and / or coefficients), or using a pre-deployed model (including its structure and / or coefficients) that is readily available, can be called model inheritance. Continuing to use functionality, or using pre-deployed functionality that is readily available, can be called functionality inheritance.

[0101] As described above, the first network device may include the target network device. Based on this, in this application, according to the first information received from the terminal device, the target network device can determine whether the terminal device, after switching to the target cell, can inherit its functions, models, and other information from the serving cell, thereby avoiding unnecessary loading of new models / functions and improving work efficiency.

[0102] The following provides detailed examples of the first model information and the first functional information.

[0103] In some embodiments, the first model information may be related to one or more of the following: model, model structure, model coefficients, etc. The model may include one or more of the following: model structure, model coefficients.

[0104] Optionally, the first model information may be used to indicate one or more of the following: models that the terminal device can support, models that the terminal device can use, models that the terminal device has already used, model structures that the terminal device can support, model structures that the terminal device can use, and model structures that the terminal device has already used.

[0105] The models that a terminal device can support can be understood as the models corresponding to the capabilities of the terminal device. For example, the models that can be supported can be a subset of the first capability information.

[0106] The models that a terminal device can use can be understood as models that the terminal device can actually use, or models that are ready to be used. For example, models that a terminal device can use can include: models that the terminal device has already deployed, models that the terminal device has optimized, and models that the terminal device can use at any time. For example, models that a terminal device can use can be a subset of models that the terminal device can support.

The model actually used can be a model that is currently in use or has been used in the past. For example, the model already used by the terminal device can be a subset of the models that the terminal device is capable of using.

[0108] This application does not limit the method of indicating the model. For example, the model can be directly configured or indicated.

[0121] This application does not limit the way use cases are indicated. For example, use cases can be directly configured. Alternatively, use cases can be indicated by use case IDs or a list of IDs. Exemplarily, the first use case information may include one or more of the following: use case IDs or a list of IDs that the terminal device can support, use case IDs or a list of IDs that the terminal device can use, and use case IDs or a list of IDs that the terminal device has already used.

[0122] On the one hand, when the first network device includes the target network device, the first network device can determine whether to use or continue to use the corresponding model, model structure, function, or use case in the target cell based on one or more of the models, model structures, functions, and use cases already used by the terminal device.

[0123] In related technologies, wireless AI solutions (such as AI models or AI functions) are often built in a scenario-based manner and are often associated with the capabilities of terminal devices and network devices. This application combines the functions / models / model structures / use cases that terminal devices have already used or can use to further determine whether the functions / models / model structures / use cases can be inherited. If the functions / models / model structures / use cases can be inherited, then problems such as resource waste and low efficiency caused by redeployment, compilation, and debugging of functions / models / model structures / use cases can be avoided or mitigated.

[0124] On the other hand, the first network device can determine whether the terminal device can use a specific model, model structure, function, or use case in the cell corresponding to the first network device based on one or more of the models, model structures, functions, and use cases that the terminal device can support. For example, compared with the serving cell, if one or more of the environment, network device capabilities, or functions supported by the network device change in the target cell, a model that the terminal device cannot use in the serving cell may be usable in the target cell. In this case, the first network device may include the target network device. The target network device can determine whether the terminal device can use a specific model, model structure, function, or use case in the target cell by obtaining one or more of the models, model structures, functions, and use cases that the terminal device can support based on the first information.

[0125] On the other hand, for terminal devices, the supported models, the models that can be directly deployed and used, the models that have already been deployed and are usable, and the models that are in use are all different types of model states on the terminal device side. If the terminal device can clearly inform the network side of the model information corresponding to the above different situations, it will help avoid unnecessary model redeployment, loading, and compilation work for the terminal device.

[0126] In some embodiments, when the first information is sent by the terminal device, the first information may be carried in a first message. The first message may satisfy one or more of the following: the first message is used to report the capability information of the terminal device, the first message is a message in the random access process, the first message is a reconfiguration completion message, and the first message is a handover confirmation message.

[0127] For example, a terminal device can send the first information via a capability reporting message. Alternatively, a terminal device can report the first information via a random access procedure message. This random access procedure message may include one or more of message 1 (msg1), message 3 (msg3), and message A (msgA). Another example is that a terminal device can send the first information via an RRC message. Furthermore, during cell handover, a terminal device can send the first information via a reconfiguration completion message and / or a handover confirmation message.

[0128] In some embodiments, when the first information is sent by the second network device, the first information may be carried in a handover request message.

[0129] For example, the second network device can indicate the first information in the handover request message. Alternatively, the second network device can indicate the first information in the RRC container of the handover request message.

[0130] In some embodiments, the first network device may correspond to a first cell. In response to one or more of the following, the first network device may receive first information sent by the second network device and / or the terminal device: the terminal device accesses the first cell; the terminal device enters the first cell via handover; the terminal device enters the first cell via re-establishment; or the terminal device enters the first cell via cell reselection.

[0131] The method shown in Figure 5 may include step S520.

[0132] In step S520, the terminal device can send the sixth information to the second network device.

[0133] The sixth piece of information may be used to indicate one or more of the following: first capability information, first functional information, and first model information. Detailed explanations of the first capability information, first functional information, and first model information are provided above and will not be repeated here.

[0134] In some embodiments, the sixth information may be used to determine the model and / or functions used by the terminal device in the target cell.

[0135] Optionally, the first information can be determined based on the sixth information. For example, the second network device can receive the sixth information sent by the terminal device, determine the first information based on the sixth information, and then send the first information to the first network device.

[0136] In some embodiments, the first information can be the same as the sixth information. That is, the second network device can transmit the sixth information transparently. In other words, the second network device can send the sixth information as the first information directly to the first network device without parsing the sixth information.

[0137] In other embodiments, the first information may be different from the sixth information. For example, the second network device may parse the received sixth information, process the sixth information to obtain the first information, and then send the first information to the first network device.

[0138] In some embodiments, the terminal device may send the sixth information via a random access procedure message. This random access procedure message may include one or more of msg1, msg3, and msgA. Alternatively, the terminal device may send the sixth information via an RRC message. Furthermore, during cell handover, the terminal device may send the sixth information via a reconfiguration completion message and / or a handover confirmation message.

[0139] Figure 6 is a schematic flowchart of another wireless communication method provided in the embodiments of the application. The method shown in Figure 6 can be executed by one or more of a first network device, a terminal device, and a second network device.

[0140] The method shown in Figure 6 may include step S610.

[0141] In step S610, the first network device sends the second information.

[0142] Step S610 may include steps S611 and / or S612. In step S611, the first network device sends second information to the terminal device. In step S612, the first network device sends second information to the second network device.

[0143] When the receiving end of the second information includes a second network device (i.e., step S612), the second information can be carried in a handover request response message (HANDOVER REQUEST ACKNOWLEDGE); when the receiving end of the second information includes a terminal device (i.e., step S611), the second information can be carried in an RRC reconfiguration message.

[0144] For example, the first cell can indicate the second information through a handover request response message. Alternatively, the first cell can indicate the second information through the RRC container in the handover request response message.

[0145] The second information may be used to indicate one or more of the following: second functional information of the terminal device in the first cell, second model information of the terminal device in the first cell, and second capability information of the terminal device in the first cell.

[0146] The second model information can indicate model-related information of the terminal device in the first cell. The second function information can indicate function-related information of the terminal device in the first cell. The second capability information can indicate the capabilities that the terminal device can support in the first cell.

[0147] The terminal device can determine its functions, models, and capabilities in the first cell based on the second information. This may allow it to inherit functions and models used in other cells, thereby avoiding additional model updates and replacements, and thus avoiding the deployment, compilation, and debugging of new models. For example, if the first cell is the target cell, the target cell can use the second information to instruct the terminal device to continue using the deployed model or model structure (e.g., under a certain function or a set of functions).

[0148] It should be noted that the methods shown in Figures 5 and 6 can be implemented individually or in combination. For example, the first network device can execute both step S510 and step S610. The second information can be determined based on the first information.

[0149] In some embodiments, the second model information may be used to indicate one or more of the following: a model that the terminal device uses or continues to use in the first cell; a model that the terminal device can use or can continue to use in the first cell; a model that the terminal device cannot use or cannot continue to use in the first cell; a model structure that the terminal device uses or continues to use in the first cell; a model structure that the terminal device can use or can continue to use in the first cell; and a model structure that indicates that the terminal device cannot use or cannot continue to use in the first cell.

[0150] As described above, a model can be indicated by a model ID or a list of model IDs. For the second model information, the second model information can be used to indicate one or more of the following: model IDs or a list of IDs used or continued to be used by the terminal device in the first cell; model IDs or a list of IDs that the terminal device can use or can continue to use in the first cell; model IDs or a list of IDs that the terminal device cannot use or cannot continue to use in the first cell; model structure IDs or a list of IDs used or continued to be used by the terminal device in the first cell; model structure IDs or a list of IDs that the terminal device can use or can continue to use in the first cell; and model structure IDs or a list of IDs that indicate that the terminal device cannot use or cannot continue to use in the first cell.

[0151] In some embodiments, the second functional information may be used to indicate one or more of the following: functions that the terminal device uses or continues to use in the first cell; functions that the terminal device can use or can continue to use in the first cell; functions that the terminal device cannot use or cannot continue to use in the first cell; use cases that the terminal device uses or continues to use in the first cell; use cases that the terminal device can use or can continue to use in the first cell; and use cases that the terminal device cannot use or cannot continue to use in the first cell.

[0152] As described above, functions can be indicated by function IDs or a list of function IDs, and use cases can be indicated by use case IDs or a list of use case IDs. Secondary function information can be used to indicate one or more of the following: function IDs or a list of IDs used or continued to be used by the terminal device in the first cell; function IDs or a list of IDs that the terminal device can use or can continue to use in the first cell; function IDs or a list of IDs that the terminal device cannot use or cannot continue to use in the first cell; use case IDs or a list of IDs used or continued to be used by the terminal device in the first cell; use case IDs or a list of IDs that the terminal device can use or can continue to use in the first cell; and use case IDs or a list of IDs that the terminal device cannot use or cannot continue to use in the first cell.

[0153] In some embodiments, the second capability information may be used to indicate one or more of the following: the ability of the terminal device to be used or to continue to be used in the first cell; the ability of the terminal device not to be used or to continue to be used in the first cell.

[0154] In some embodiments, the second information can be represented by a bitmap.

[0155] For example, the second piece of information can be indicated by the first bitmap. One or more bits in the first bitmap can represent whether a specific model, model structure, function, or use case can continue to be used.

[0156] In some embodiments, the size or order of the bitmap (e.g., the first bitmap) may be determined by the first information. For example, the size of the bitmap may be determined by the size of the first capability information, first functional information, or first model information indicated in the first information. Similarly, the order of the bitmap may be determined by the order of the first capability information, first functional information, or first model information indicated in the first information.

[0157] For example, if the first information indicates information about N models, model structures, functions, or use cases related to the terminal device, the second information can determine, through an N-bit bitmap, the AI ​​capabilities, functions, or models that the terminal device can use in the first cell. For instance, the k-th bit can represent whether the k-th model, model structure, function, or use case can be used or continue to be used in the first cell.

[0158] For example, if the first information indicates information about N models, model structures, functions, or use cases related to the terminal device, the second information can be used to determine the AI ​​capabilities, functions, or models that the terminal device can use in the first cell among the aforementioned N models, model structures, functions, or use cases through a bitmap of M bits (e.g., M = 2N, where every 2 bits indicate a UE's first capability, first function information, or first model information). For example, bits k1 and k2 represent whether the k-th model, model structure, function, or use case can continue to be used in the first cell, is a candidate for use, needs to update model parameters, or needs to be updated, etc.

[0159] In some embodiments, the first network device may send third information. For example, the first network device may send third information to a terminal device. Alternatively, the first network device may send third information to a second network device.

[0160] The third information can be used to update the second functional information and / or the second model information. For example, the third information can be used to indicate one or more of the following information to be updated: model, model structure, function, use case. The third information may not be indicated in the first information.

[0161] In some embodiments, the second network device may send seventh information to the terminal device.

[0162] The seventh piece of information can be used to update the second functional information and / or the second model information. For example, the seventh piece of information can be used to indicate one or more of the following: model, model structure, function, use case. The seventh piece of information may not have been indicated in the first piece of information.

[0163] Optionally, the seventh information can be determined based on the third information. For example, the second network device can receive the third information sent by the first network device and send it directly to the terminal device as the seventh information. It is understood that in this case, the seventh information and the third information can be the same. For the terminal device, both the first and second network devices can send the third information to it. That is, the terminal device can receive the third information sent by either the first or second network device. Alternatively, the second network device can receive the third information sent by the first network device, parse it to obtain the seventh information, and then send the obtained seventh information to the terminal device.

[0164] In some embodiments, the first network device may send fourth information. For example, the first network device may send fourth information to a terminal device. Alternatively, the first network device may send fourth information to a second network device.

[0165] The fourth information can be used to indicate information related to the model coefficients. For example, the fourth information can be used to indicate updated model coefficients. For instance, if the terminal device can continue to use a specific model structure, the first network device can send the fourth information when the model coefficients need to be updated.

[0166] In some embodiments, the second network device may send the eighth information to the terminal device.

[0167] The eighth message can be used to indicate information related to the model coefficients. For example, the eighth message can be used to indicate updated model coefficients. Exemplarily, if the terminal device can continue to use a specific model structure, the first network device can send the eighth message when the model coefficients need to be updated.

[0168] Optionally, the eighth information can be determined based on the fourth information. For example, the second network device can receive the fourth information sent by the first network device and send it directly as the eighth information to the terminal device. It is understood that in this case, the eighth information and the fourth information can be the same. For the terminal device, both the first and second network devices can send the fourth information to it. That is, the terminal device can receive the fourth information sent by either the first or second network device. Alternatively, the second network device can receive the fourth information sent by the first network device, parse it to obtain the eighth information, and then send the obtained eighth information to the terminal device.

[0169] The method shown in Figure 6 may include step S620.

[0170] In step S620, the second network device can send a fifth message to the terminal device.

[0171] The fifth message can be used to indicate one or more of the following: the second functional information of the terminal device in the first cell, the second model information of the terminal device in the first cell, and the second capability information of the terminal device in the first cell. Detailed descriptions of these information are provided above and will not be repeated here.

[0172] Optionally, the fifth information can be determined based on the second information. For example, the second network device can receive the second information sent by the first network device, determine the fifth information based on the second information, and then send the fifth information to the terminal device.

[0173] In some embodiments, the fifth information may be the same as the second information. That is, the second network device may transmit the second information transparently. In other words, the second network device may not parse the second information and directly send the second information as the fifth information to the terminal device.

[0174] In other embodiments, the fifth information may be different from the second information. For example, the second network device may parse the received second information, process the second information to obtain the fifth information, and then send the fifth information to the terminal device.

[0175] In some embodiments, the fifth piece of information may be carried in an RRC reconfiguration message.

[0176] In some embodiments, the fifth information can be indicated by a bitmap.

[0177] For example, the fifth piece of information can be indicated through the second bitmap. One or more bits in the second bitmap can represent whether a specific model, model structure, function, or use case can continue to be used.

[0178] In some embodiments, the size or order of the bitmap (e.g., a second bitmap) may be determined by the first information. For example, the size of the bitmap may be determined by the size of the first capability information, first functional information, or first model information indicated in the first information. Similarly, the order of the bitmap may be determined by the order of the first capability information, first functional information, or first model information indicated in the first information.

[0179] For example, if the first information indicates information about N models, model structures, functions, or use cases related to the terminal device, the fifth information can determine, through an N-bit bitmap, the AI ​​capabilities, functions, or models that the terminal device can use in the first cell. For instance, the k-th bit can represent whether the k-th model, model structure, function, or use case can be used or continue to be used in the first cell.

[0180] For example, if the first information indicates information about N models, model structures, functions, or use cases related to the terminal device, the fifth information can determine the AI ​​capabilities, functions, or models that the terminal device can use in the first cell among the aforementioned N models, model structures, functions, or use cases through a bitmap of M bits (e.g., M = 2N, where every 2 bits indicate a UE's first capability, first function information, or first model information). For example, bits k1 and k2 represent whether the k-th model, model structure, function, or use case can continue to be used in the first cell, is a candidate for use, needs to update model parameters, or needs to be updated, etc.
