Abstract

The embodiment of the invention provides a channel state information reporting method, receiving method and equipment. The reporting method comprises the following steps: acquiring reference signal resource configuration information, wherein antenna port configuration information in the reference signal resource configuration information is used for indicating an antenna port structure; receivinga reference signal sent by a base station according to the reference signal resource configuration information; selecting a precoding matrix from a codebook based on the received reference signal, wherein the structure of the precoding matrix is corresponding to the antenna port structure indicated by the antenna port configuration information; and reporting PMI for indicating the selected precoding matrix to the base station. Through the technical scheme provided by the invention, the problem of reporting the CSI under an ASS base station scene is solved, and the precision of the reported CSIis improved.

Description

[0001] This application is a divisional case of the patent application with the application number 201380002671.5 and the invention titled channel state information reporting method, receiving method and equipment. technical field [0002] Embodiments of the present invention relate to communication technologies, and in particular to a method for reporting channel state information, a receiving method and equipment. Background technique [0003] Through transmit precoding and receive combining, a multiple input multiple output (Multiple Input Multiple Output, MIMO for short) system can obtain diversity and array gain. Using the precoded MIMO system, its received signal can be expressed as: y=HVs+n. Among them, y is the received signal vector, H is the channel matrix, V is the precoding matrix, s is the transmitted symbol vector, and n is the interference and noise vector. To achieve optimal precoding, the transmitter needs to be fully aware of channel state information (Cha...
