[0062] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0063] In recent years, artificial intelligence (AI) research and related achievements have achieved remarkable results in many fields. AI has become a new approach for people to solve and address problems. Among these numerous research areas, neural network-based AI research is an extremely important one. The basic structure of a simple neural network consists of an input layer, a hidden layer, and an output layer, as shown in Figure 2. The input layer receives data, the hidden layer processes the data, and the output layer produces the final result.

[0064] With the continuous development of neural network research, neural network deep learning algorithms have been proposed in recent years. As shown in Figure 3, this multi-hidden layer neural network structure greatly improves the processing capability of the network and is widely used in pattern recognition, signal processing, optimization combination, anomaly detection, and other aspects.

[0065] With the development of deep learning, convolutional neural networks have also been further studied. The basic structure of a convolutional neural network includes an input layer, multiple convolutional layers, multiple pooling layers, a fully connected layer, and an output layer, as shown in Figure 4. The introduction of convolutional and pooling layers effectively controls the rapid increase in network parameters, limits the number of parameters, exploits the characteristics of local structures, and improves the robustness of the algorithm.

[0066] To facilitate a better understanding of the embodiments of the present application, an example of the combination of the AI ​​model related to the present application and wireless communication is described.

[0067] Current wireless communication systems offer greater flexibility than ever before, emphasizing broad applicability across diverse scenarios and full utilization of limited resources. However, the fundamental principles underlying much of this work are still based on theoretical modeling of actual communication environments or simple parameter selection. The benefits of this basic approach are gradually diminishing in diverse and complex communication environments, as exemplified by the conditional switching solutions and issues described in the previous two sections. To address this situation, it is necessary to adopt new methods and approaches, integrating them with traditional wireless communication theories and systems, to explore new approaches, break through performance bottlenecks, and further enhance the performance of wireless communication systems.

[0068] For example, AI model + CSI feedback: Use artificial intelligence (AI) / machine learning (ML) technology to compress and decompress CSI, reduce air interface transmission overhead, and improve the accuracy of CSI feedback information.

[0069] Another example is AI model + beam management: using artificial intelligence (AI) / machine learning (ML) technologies to predict beam information in the time and spatial domains, reducing measurement overhead and latency, and improving beam selection accuracy.

[0070] Another example is AI model + positioning technology: using artificial intelligence (AI) / machine learning (ML) technology to predict UE location information and improve the accuracy of UE location information in NLOS scenarios.

[0071] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0072] The lifecycle management of AI models includes model generation, deployment, transmission, monitoring, and updates. During model monitoring, the terminal and / or network must evaluate the performance of the currently running AI model and, based on the results, determine whether to fall back to traditional communication methods. However, how to monitor network models remains a challenge.

[0073] Based on the above problems, the present application proposes a model monitoring solution, whereby the first communication device can determine whether the first network model is valid based on the first information, that is, the first communication device can monitor the validity of the first network model.

[0074] The technical solution of this application is described in detail below through specific embodiments.

[0075] FIG5 is a schematic flow chart of a model monitoring method 200 according to an embodiment of the present application. As shown in FIG5 , the model monitoring method 200 may include at least part of the following contents:

[0076] S210, the first communication device determines whether the first network model is valid based on the first information; wherein the first information is at least one of the following: location information of the terminal device, configuration information associated with the first network model, performance indicator information associated with the first network model, capability information of the terminal device, a timer associated with the first network model, and the number of times the first network model is used.

[0077] In the embodiment of the present application, the first communication device may determine whether the first network model is valid based on the first information, that is, the first communication device may monitor the validity of the first network model.

[0078] In some embodiments, the first communication device is a terminal device, or the first communication device is a network device.

[0079] In some embodiments, the first network model is deployed on the terminal side and / or the network side.

[0080] For example, the terminal device determines whether the first network model deployed on the terminal side is valid based on the first information.

[0081] For another example, the terminal device determines whether the first network model deployed on the network side is valid based on the first information.

[0082] For another example, the network device determines whether the first network model deployed on the network side is valid based on the first information.

[0083] For another example, the network device determines whether the first network model deployed on the terminal side is valid based on the first information.

[0084] In some embodiments, the first network model is used for CSI feedback. Specifically, the CSI can be compressed and decompressed based on the first network model to reduce air interface transmission overhead and improve the accuracy of CSI feedback information.

[0085] In some embodiments, the first network model is used for spatial filter management. Specifically, spatial filter information can be predicted in the time domain / spatial domain based on the first network model, which has low measurement overhead and delay, and improves the accuracy of spatial filter selection.

[0086] In some embodiments, the first network model is used for positioning. Specifically, the location information of the terminal device can be predicted based on the first network model to improve the accuracy of the location information of the terminal device in the NLOS scenario.

[0087] In the application embodiments, a spatial filter may also be referred to as a beam, or a spatial relation, or a spatial setting, or a spatial domain filter, or a reference signal.

[0088] It should be noted that the first network model described in the embodiment of the present application can also be used to implement other functions, and the present application does not limit this.

[0089] The embodiment of the present application does not limit the model structure and model parameters of the first network model.

[0090] In some embodiments, before the first communication device determines whether the first network model is valid based on the first information, the first communication device receives the first information, or the first communication device obtains the first information.

[0091] For example, the first communication device receives the first information sent by the second communication device. That is, the second communication device can obtain the first information through monitoring or other means, and send the first information to the first communication device, so that the first communication device determines whether the first network model is valid based on the first information. Optionally, the first information can be carried by one of the following: Radio Resource Control (RRC) signaling, downlink control information (DCI), media access control layer control element (MAC CE), broadcast message, PC5 message, sidelink control information (SCI).

[0092] For another specific example, the first communication device may obtain the first information through monitoring or other means, and the first communication device may determine whether the first network model is valid based on the first information.

[0093] In some embodiments, the first communication device is a terminal device, and the second communication device is a network device.

[0094] In some embodiments, the first communication device is a network device, and the second communication device is a terminal device.

[0095] In some embodiments, the first communication device is a terminal device, and the second communication device is another terminal device.

[0096] For example, the first network model is deployed on the UE side, the UE side monitors the performance of the communication system and reports the monitoring results to the network, and the network determines whether the first network model is valid based on the monitoring results.

[0097] For another example, the first network model is deployed on the UE side, the UE side monitors the performance of the communication system, and determines whether the first network model is valid based on the monitoring result.

[0098] For another example, the first network model is deployed on the network side, the network side monitors the performance of the communication system, and sends the monitoring results to the terminal, and the terminal determines whether the first network model is valid based on the monitoring results.

[0099] For another example, the first network model is deployed on the network side, and the network side monitors the performance of the communication system and determines whether the first network model is valid based on the monitoring result.

[0100] In some embodiments, when the first information is the location information of the terminal device, the location information of the terminal device is determined based on the service cell information of the terminal device, or the location information of the terminal device is determined based on the transmission reception point (TRP) information accessed by the terminal device.

[0101] It should be understood that TRP can be different service access points under a cell, which can be understood as the underlying hardware transmission equipment at the cell level. UE at different locations in the cell may communicate with different TRPs.

[0102] In some embodiments, when the location information of the terminal device is determined based on the serving cell information of the terminal device, the above S210 may specifically include:

[0103] The first communication device determines whether the first network model is valid based on whether the current serving cell of the terminal device belongs to the cell set associated with the first network model.

[0104] In some embodiments, when the current serving cell of the terminal device belongs to the cell set associated with the first network model, the first communication device determines that the first network model is valid; and / or, when the current serving cell of the terminal device does not belong to the cell set associated with the first network model, the first communication device determines that the first network model is invalid.

[0105] In some embodiments, the cell set associated with the first network model is configured or indicated by a network device, or the cell set associated with the first network model is agreed upon by a protocol, and the cell set associated with the first network model is determined by a device that deploys the first network model.

[0106] For example, the cell set associated with the first network model may include at least one cell, and the at least one cell may be represented by one or more cell identifiers and / or cell frequency information, wherein the cell identifier includes the cell's physical cell identifier (Physical Cell Identifier, PCI) and / or the global cell identifier (Cell Global Identifier, CGI).

[0107] In some embodiments, the terminal device or the network device determines whether the terminal device is within the valid area of ​​the first network model by judging whether the identifier of the terminal device's current serving cell is included in the cell set associated with the first network model.

[0108] In some embodiments, the configuration information of the first network model carries a cell set associated with the first network model. Specifically, after the UE performs cell selection / reselection or handover, it is determined whether the UE's current serving cell belongs to the cell set associated with the first network model. If so, the first network model is continued to be used; otherwise, the first network model is considered unavailable.

[0109] In some embodiments, when the location information of the terminal device is determined based on the serving cell information of the terminal device, the above S210 may specifically include:

[0110] The first communication device determines whether the first network model is valid according to the first indication information;

[0111] The first indication information is used to indicate the network model information supported by the current serving cell of the terminal device, or the first indication information is used to indicate whether the current serving cell of the terminal device supports the first network model, or the first indication information is used to indicate the network model information not supported by the current serving cell of the terminal device, or the first indication information is used to indicate whether the current serving cell of the terminal device supports the network model deployed on the terminal side and / or the network side. Optionally, the network model information includes the type and / or identifier of the network model.

[0112] In some embodiments, the first indication information is carried by a system broadcast message in the current serving cell of the terminal device.

[0113] For example, in the case where the first indication information is used to indicate the network model information supported by the current service cell of the terminal device, if the first network model belongs to the network model supported by the current service cell of the terminal device indicated by the first indication information, the first communication device determines that the first network model is valid, and / or, if the first network model does not belong to the network model supported by the current service cell of the terminal device indicated by the first indication information, the first communication device determines that the first network model is invalid.

[0114] For example, in a case where the first indication information is used to indicate whether the current serving cell of the terminal device supports the first network model, if the first indication information is used to indicate that the current serving cell of the terminal device supports the first network model, the first communication device determines that the first network model is valid, and / or, if the first indication information is used to indicate that the current serving cell of the terminal device does not support the first network model, the first communication device determines that the first network model is invalid.

[0115] For example, in the case where the first indication information is used to indicate network model information that is not supported by the current service cell of the terminal device, if the first network model does not belong to the network model that is not supported by the current service cell of the terminal device indicated by the first indication information, the first communication device determines that the first network model is valid, and / or, if the first network model belongs to the network model that is not supported by the current service cell of the terminal device indicated by the first indication information, the first communication device determines that the first network model is invalid.

[0116] For example, when the first indication information is used to indicate that the current serving cell of the terminal device supports the network model deployed on the terminal side, if the first network model is a network model deployed on the terminal side, the first communication device determines that the first network model is valid, and / or, if the first network model is not a network model deployed on the terminal side, the first communication device determines that the first network model is invalid.

[0117] For example, when the first indication information is used to indicate that the current service cell of the terminal device does not support the network model deployed on the terminal side, if the first network model is a network model deployed on the terminal side, the first communication device determines that the first network model is invalid, and / or, if the first network model is not a network model deployed on the terminal side, the first communication device determines that the first network model is valid.

[0118] For example, when the first indication information is used to indicate that the current serving cell of the terminal device supports the network model deployed on the network side, if the first network model is a network model deployed on the network side, the first communication device determines that the first network model is valid, and / or, if the first network model is not a network model deployed on the network side, the first communication device determines that the first network model is invalid.

[0120] Exemplarily, the AI ​​model information deployed on the terminal side is Model_BM_Index=1, indicating that the AI ​​model is used for beam management and the model index is 1. For example, if the AI ​​model identifier indicated by the first indication information in the system broadcast message is 1, it means that the AI ​​model deployed on the terminal side is still applicable to the current cell. Otherwise, the AI ​​model deployed on the terminal side is considered to be inapplicable / invalid in the current cell. For another example, if the AI ​​model information supported by the current cell indicated by the first indication information in the system broadcast message includes Model_BM_Index=1, Model_BM_Index=3, and Model_BM_Index=5; if Model_BM_Index=1 is included in the AI ​​models supported by the current cell indicated by the first indication information, it is determined that the cell supports the deployed AI model.
