Abstract
The present invention belongs to the field of communications technologies, and discloses a channel state information CSI feedback method and an apparatus. The method includes: determining a codebook of at each transport layer CSI of user equipment UE, where the codebook of the CSI at each transport layer of the UE is: W=W×W, an element Xin Wis a weighting coefficient corresponding to each codeword in W, and i is an integer greater than or equal to 1 and less than or equal to K; determining a quantity Nof bits occupied by a quantized value of an ielement in W, where quantized values of at least two elements in Woccupy different quantities of bits; and feeding back the quantized value of the ielement to a network device based on N.
