Abstract

Embodiments of the present invention provide a channel state information reporting method, receiving method and equipment. The reporting method includes: obtaining reference signal resource configuration information, the antenna port configuration information in the reference signal resource configuration information is used to indicate the antenna port structure; according to the reference signal resource configuration information, receiving the reference signal sent by the base station; based on the received reference signal, from Select a precoding matrix in the codebook, the structure of the precoding matrix corresponds to the antenna port structure indicated by the antenna port configuration information; report the PMI used to indicate the selected precoding matrix to the base station. The technical scheme of the present invention solves the problem of reporting CSI in the ASS base station scenario, and improves the accuracy of the reported CSI.

Description

technical field [0001] 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 [0002] 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 (Channel State Information, referred to as CSI). In the existing Long Term Evolution (LTE for short) R8-R11 system, CSI includes Rank Indicator (RI for short), Precoding Matrix Indicator (PMI for short) and Channel Quali...
