Our society is undergoing a digitization revolution. In the last few years, artificial intelligence (AI) and machine learning (ML) methods are widely used in various industries to advance innovation and increase process efficiency. However, for the network design, with the dramatic increase of both the extraordinary amount of data and network complexity, conventional approaches will not be able to provide swift solutions in many cases. Hence, AI/ML will be an indispensable technology to improve the performance for future wireless communication networks.

It is noted that the AI/ML model selection refers to select an AI model or an ML model.

In an AI/ML model over an air interface, a trained AI/ML model by a model training function is used for a model inference function, and then the model inference function using the trained AI/ML model to produce a set of outputs based on a set of inputs. As discussion in the before meetings, the model inference function and the model training function can be located in the same side or the different sides, whatever in one-sided AI/ML model or two-sided AI/ML model. Hence, due to the locations of the model inference function and the model training function in different use cases, the process of the AI/ML model selection may be different.

When the model inference function and the model training function are located in the same side, a node (e.g., gNB, network (NW) , or UE) knows the trained AI/ML model, and the nodes also knows its own requirement. Hence, the AI/ML model selection is up to the node implementation. However, the signaling and assistance information about data collection for model training, and/or model interface and others, are not included in the procedure of the AI/ML model selection.

When the model inference function and the model training function are located in different sides, two nodes do not know information about at least one AI/ML model. Moreover, a model transfer occurs in this case. Hence, in order to process the AI/ML model selection between or among nodes, the AI/ML model selection can be initiated by two methods.

It should be noted that the first BS or the at least one second BS can refer to, but is not limited to, a gNB or a network (NW) .

The above-mentioned AI/ML model selection can be triggered by the following scenarios. When a node decides to use an AI/ML model in some use cases in a wireless communication. Alternatively, when some new requirements of a node appear, the node can select another AI/ML model/model. Alternatively, when a scenario has be changed, a node can select another AI/ML model.

For the process of the AI/ML model selection, a post processing should also be considered. This function can be located in the same side as a model training function, such as a gNB, a NW, or a server.

When AI/ML models are identified as candidate AI/ML models, a node can initiate the post processing for the candidate AI/ML models before a model transfer. In an example, the complexity of the AI/ML models can be reduced. In another example, the accuracy of the AI/ML models can be increased.

Information of the AI/ML model selection can be configured or provided. When a node which receives information, an AI/ML model might not meet all requirements or might only meet all the requirements strictly. A rule for the AI/ML model selection can include setting up priorities of requirements and/or setting up group priorities of requirements.

In an example, each of the requirements can be marked with a priority. For example, the type of an AI/ML model is priority 1, the complexity of an AI/ML model is priority 2, the latency of an AI/ML model is 3, and the generalization of an AI/ML is 4. When all the requirements are met, an AI/ML model or models can be regard as the most suitable AI/ML model or models, which have the highest probability to be transferred.

In another example, each of the requirements can be marked with a priority. For example, the type of an AI/ML model is priority 1, the complexity of an AI/ML model is priority 2, the latency of an AI/ML model is 3, and the generalization of an AI/ML is 4. When several requirements are met, an AI/ML model or models can be regard as the suitable AI/ML model or models, which have probability to be transferred.

In another example, each of the requirements can be marked with a priority. For example, the type of an AI/ML model is priority 1, the complexity of an AI/ML model is priority 2, the latency of an AI/ML model is 3, and the generalization of an AI/ML is 4. When an AI/ML model or models in a priority group meet several requirements, the priority group has probability to be transferred. In summary, it is necessary to index or configure priorities of requirements.

The messages mentioned above can be higher layer messages and/or physical messages, such as radio resource control (RRC) messages, MAC CE, control protocol data unit (PDU) , downlink control information (DCI) , data PDU, or non-access stratum (NAS) . The messages can be sent by unicast, broadcast, or groupcast.

Furthermore, the messages mentioned above can be out of 3GPP. Alternatively, the messages mentioned above can be Xn messages.
