Description

A communication method and apparatus Cross-reference of related applications This application claims priority to Chinese Patent Application No. 202410204872.3, filed on February 23, 2024, entitled "A Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology Currently, ray tracing can be used to model wireless channels in specific environments and at specific base station and terminal locations. The general approach involves modeling the direct and reflected propagation of rays to calculate their propagation within the environment and thus determine multipath information. However, ray tracing requires modeling and calculating multipath information for specific environments and the locations of specific transmitters and receivers. When the positions of the transmitters or receivers change, recalculation is necessary, resulting in significant processing overhead for determining multipath information. Summary of the Invention This application provides a communication method and apparatus for reducing the processing overhead of a communication device. In a first aspect, embodiments of this application provide a first communication method, which can be applied to a first communication device. The first communication device can be one or more devices, such as network devices or terminal devices, or it can be a component, such as a processor, chip, or chip system, or it can be a logic module or software capable of implementing all or part of the functions of the first communication device. The method includes: acquiring first environmental information, which indicates the environmental characteristics of a third communication device; acquiring first location information, which indicates the location of the first communication device; inputting the first environmental information and the first location information into a first model; determining multipath information, which indicates information about multiple paths used for signal transmission between the first communication device and the third communication device. The third communication device may be the same as or different from a second communication device. In this embodiment, the first communication device receives first environmental information and processes it and its location using a first model to obtain multipath information. On one hand, the first communication device does not need to determine the first environmental information itself; on the other hand, the first environmental information of the third communication device is less likely to change. Therefore, even if the location of the first communication device changes, it does not need to repeatedly acquire the first environmental information, thus reducing the resources required for the first communication device to determine multipath information and lowering its processing overhead (e.g., computational overhead). Furthermore, the first environmental information can be shared by multiple first communication devices, reducing the processing overhead of the first communication devices in the entire communication system. Additionally, when the third communication device is different from the second communication device, it is equivalent to the second communication device forwarding the first environmental information from the third communication device to the first communication device, achieving indirect sharing of the first environmental information. This allows the first communication device to acquire environmental information from more communication devices, further reducing its computational overhead. Moreover, after predicting multipath information using the first model, the first communication device can use the multipath information to adjust communication-related parameters, such as beamforming, improving the communication quality of the first communication device. In one optional implementation, after determining the multipath information, the method further includes: acquiring second information, the second information indicating configuration information of a first communication device and/or configuration information of a third communication device. Based on the second information and the multipath information, determining one or more pieces of channel information, the one or more pieces of channel information used to indicate channel parameters between the first communication device and the third communication device. Thus, after determining the multipath information, the first communication device can further acquire the second information, and the method by which the first communication device acquires the second information is not limited. The first communication device can determine one or more pieces of channel information based on the second information and the multipat
