Description

CROSS REFERENCE TO RELATED APPLICATION This is a continuation of International Application No. PCT/CN2023/113640 filed on Aug. 17, 2023, the disclosure of which is hereby incorporated by reference in its entirety. TECHNICAL FIELD The present disclosure relates to the technical field of communication, and more particularly to a method of wireless communication and a communication device. BACKGROUND In various communication processes of communication systems, a model-based communication mode is introduced. For example, in a scheme based on non-orthogonal communication, a model may be introduced at the sending end to transmit a target signal. For another example, in a scheme based on non-orthogonal communication, a model may be introduced at the receiving end to receive the target signal. Generally speaking, the model used by the sending end for transmitting the target signal needs to match the model used by the receiving end for receiving the target signal, which helps to improve the success rate of the model-based communication process. However, in the conventional signal transmission process, the sending end and the receiving end cannot obtain each other's models, which may result in a mismatch between the model used at the sending end and the one used at the receiving end.
