COMMUNICATION METHOD AND APPARATUS, AND STORAGE MEDIUM

WIPO Patent Application WO/2024/065183

A1

Provided in the embodiments of the present application are a communication method and apparatus, and a storage medium. The method comprises: sending a first reference signal; and receiving first information, the first information indicating a first parameter and a second parameter, wherein the first parameter and the second parameter are obtained according to the first reference signal, the first parameter is used for representing an association relationship between channel gains of a plurality of sub-channels, the second parameter is used for representing a channel gain of a first sub-channel among the sub-channels, and the first parameter and the second parameter are used for determining one or more of the following: a modulation and coding scheme (MCS) of each of a plurality of codewords, and a first granularity of a channel quality of a sub-channel in a time domain and/or frequency domain. By means of the method, a modulation and coding scheme of each codeword can be determined only by sending a first parameter and a second parameter, such that the spectral efficiency of a MIMO system can be improved.
