Abstract:
A method and apparatus for precoding matrix indicator feedback reduce a quantity of bits in the feedback. In the method, a terminal device receive a reference signal from a base station and determines a precoding matrix W in a precoding matrix set corresponding to a rank indication. W satisfies W=W 1 ×W 2 ×W 3 , where W 1 , W 2  and W 3  are matrices and respectively corresponding to a first, second and third precoding matrix indicator. None of W 1 , W 2 , and W 3  is an identity matrix, and the 2M columns in W 1  comprise every column in W 1 ×W 2 . The terminal device transmits the rank indication, the first precoding matrix indicator, the second precoding matrix indicator, and the third precoding matrix indicator to the base station.

Claim (Index 6):
The method according to  claim 1 , wherein T column vectors in 2K column vectors in W 2  are indicated by the first precoding matrix indicator, wherein T is an integer greater than or equal to 2, and wherein T is less than K; and\n wherein 2K\u2212T column vectors in W 2  except the T column vectors are indicated by the T column vectors and the second precoding matrix indicator.
