Abstract
In a method, a terminal device reports, to a network device, a full-power transmission codebook subset corresponding to a frequency band supported by the terminal device before transmission channel switching. The network device or the terminal device in a communications system may determine, according to a specified rule and full-power transmission codebook subsets corresponding to a plurality of source frequency bands, a full-power transmission codebook subset corresponding to a target frequency band after transmission channel switching. The plurality of source frequency bands are frequency bands in which a plurality of target antenna ports are located before antenna port switching, and the plurality of target antenna ports are antenna ports in the target frequency band after antenna port switching.
