CHANNEL STATE INFORMATION REPORT METHOD AND APPARATUS, AND CHANNEL STATE INFORMATION RECEIPT APPARATUS AND APPARATUS

摘要

the present invention provides a method of reporting csi channel status information, including: receiving (101) a reference signal from a base station; select (102), based on the reference signal, a pre-coding matrix from a coding table, where the coding table includes a pre-coding matrix wew = asv, where a matrix v is a matrix n × v, n is the number of reference signal ports, v = n, s is a line selection matrix used to select one or more line vectors from matrix v, and a is a constant; and sending (103) csi to the base station, where the csi includes a pmi precoding matrix indicator and the pmi corresponds to the selected precoding matrix. in the modalities of the present invention, by adjusting the codebook structure, an appropriate pre-coding matrix can be selected according to an interference situation, in order to select an antenna for data transmission and antenna power to reduce the amount of programming resources wasted due to interference control by a base station.
