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 17):
The non-transitory computer readable medium according to  claim 15 , wherein\n W 1  satisfies W 1 = [ X 1 0 0 X 1 ] , wherein X 1  is a matrix of N t /2 rows and M columns, wherein X 1 =[v 0  . . . v m-1 ], wherein v 0  is a column vector comprising N t /2 elements, and wherein o is an integer ranged from 0 to M\u22121; and\n wherein any column in W 3  is represented as \n [ e l \u03c6 n \ue89e e l ] , wherein \u03d5 n  is a complex number, wherein \u03f5 l  is a K\u00d71 column vector, wherein an l th  element in \u03f5 l  is 1, wherein the remaining elements in \u03f5 l  are 0, and wherein l is an integer ranged from 1 to K.
