Abstract
The present disclosure relates to channel state information (CSI) receiving methods and apparatus. One example method includes transmitting a pilot, and receiving feedback of Wand Wfor each transport layer which are determined based on the pilot, where Wand Ware used to form a combined vector W for each transport layer, W=W×W, W=[bb. . . b], bis a vector to be combined, W=[XX. . . X], Xis a weighting coefficient corresponding to b, K is a quantity of vectors in W, K is a positive integer which is greater than 1, i is an integer, 1≤i≤K, and quantities of bits for feeding back at least two elements in Ware different from each other.
