Information Feedback Method, User Equipment, And Network Device

A channel state information (CSI) receiving method, comprising:

• transmitting a pilot;
• and receiving feedback of W1 and W2 for each transport layer which are determined based on the pilot, wherein W1 and W2 are used to form a combined vector W for each transport layer, W=W1×W2, W1=[b1 b2 . . . bK], bi is a vector to be combined, W2=[X1 X2 . . . XK]T, Xi is a weighting coefficient corresponding to bi, K is a quantity of vectors in W1, 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 W2 are different from each other.
