Abstract:
Embodiments of the present invention provide a method for determining a precoding matrix indicator, a receiving device, and a sending device. The method for determining a precoding matrix indicator includes: selecting, by a receive end, a precoding matrix W from a codebook based on a reference signal sent by a transmit end, where the precoding matrix W is a product of two matrices W1 and W2, where the W1 includes N B  block matrices X i , N B ≥1, and the W1 is indicated as: W1=diag{X 1 , . . . , X N B }, where 1≤i≤N B , and a column x i,j  of each block matrix X i  is a Kronecker kronecker product of a first vector A ij  and a second vector B ij , that is, x ij =A ij ⊗B ij ; and sending, by the receive end, a precoding matrix indicator PMI corresponding to the precoding matrix W to the transmit end, so that the transmit end obtains the precoding matrix W according to the PMI.

Claim (Index 7):
The non-transitory computer-readable storage medium according to  claim 6 , wherein\n all columns of the block matrix X i  are obtained by pairwisely successively calculating Kronecker products of N1 consecutive first vectors and N2 consecutive second vectors.
