Title:
INFORMATION SENDING METHOD AND APPARATUS, INFORMATION RECEIVING METHOD AND APPARATUS, AND COMMUNICATION APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/065832
Kind Code:
A1
Abstract:
The present disclosure relates to an information sending method and apparatus, an information receiving method and apparatus, and a communication apparatus and a storage medium. The information sending method comprises: preprocessing estimated full-channel information according to a first number of spatial-domain basis vectors and a second number of frequency-domain basis vectors, so as to obtain effective channel information; calculating a feature vector of the effective channel information; and inputting the feature vector into a model, so as to obtain CSI-related information, and sending the CSI-related information to a network device. According to the present disclosure, a feature vector of effective channel information can be further calculated, such that the dimension of the feature vector is unrelated to the number Nr of receiving antenna ports. Therefore, the feature vector is used as an input of a model, and it is not necessary to train different models by means of taking into account scenarios with different numbers of receiving antenna ports, thereby facilitating a reduction in the number of models that are required to be trained, that is, reducing the number of models that are required to be sent to a terminal and the number of models that are required to be stored in the terminal, and thus facilitating a reduction in signaling overheads and saving on storage space of the terminal.
