Claim Text:
1. A method for transmitting a pre-coding indicator, the method comprising: determining, by a UE, a first pre-coding indicator and a second pre-coding indicator, the first pre-coding indicator and the second pre-coding indicator corresponding to a pre-coding matrix which is equal to a matrix as a function of a first component pre-coding matrix and a second component pre-coding matrix, the first component pre-coding matrix being a block diagonal matrix with sub-matrixes on the diagonal being a Kronecker product of two diagonal matrixes, and the second component pre-coding matrix being constructed by beam-rotating vectors, each of the beam-rotating vectors being equal to a Kronecker product of two vectors; and transmitting, by the UE, the first pre-coding indicator and the second pre-coding indicator to a network side.
