Title:
INFORMATION FEEDBACK METHOD, INFORMATION FEEDBACK DEVICE AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/028641
Kind Code:
A1
Abstract:
Provided are an information feedback method, device and terminal, which relate to the field of communications. The feedback method of this disclosure comprises: obtaining pre-coding matrix indication information about multiple levels of pre-coding matrices of a pre-coding matrix used for downlink data transmission; and respectively feeding back pre-coding matrix indication information about each level of pre-coding matrix to a base station or feeding back same to the base station after performing joint encoding. The solution of this disclosure can satisfy a higher requirement for codebook feedback load.
