Title:
CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/027393
Kind Code:
A1
Abstract:
Provided in the present application are a channel state information feedback method and apparatus, which are used for realizing joint codebook design of a plurality of TRPs in a plurality of frequency bands. In the method, configuration information indicates an association relationship between a plurality of frequency bands and a plurality of TRPs, i.e. the plurality of TRPs being associated with a first frequency band, and at least one of the plurality of TRPs also being associated with a second frequency band, such that a terminal can feed back, in a targeted manner, CSI corresponding to a plurality of TRPs associated with each frequency band that use coherent joint transmission, so as to realize joint codebook design of the plurality of TRPs in a plurality of frequency bands.
