Abstract:
Provided are a method for channel information feedback in a multi-antenna system, and a terminal. The method comprises: a terminal receives CSI-RSs of M ports sent by a base station, and performs estimation according to the CSI-RSs to obtain M-dimensional downlink channel information; the terminal uses a transformation function F k  to perform a linear transformation on the M-dimensional downlink channel information, and obtains N k -dimensional kth type channels, wherein k is greater than or equal to 1 and less than or equal to K, M≥N k , and K≥1; the terminal uses a preset N k -dimensional codebook to respectively perform channel information quantisation on the k th  type channels, and determines a corresponding precoding matrix and precoding matrix indicator information (PMI k ); the terminal selects S type channels from within K type channels, and feeds index numbers of the selected channels and corresponding PMI back to the base station.

Claim (Index 4):
The method as claimed in  claim 3 , wherein for the i th  column of the matrix W k , the k i th  element is 1 and the elements other than the k i th  element are 0, and wherein i is greater than or equal to 1 and is less than or equal to N k , and k i  is greater than or equal to 1 and is less than or equal to M.
