Abstract
Disclosed is a method for transmitting channel state information, for realizing the transmission of channel information which supports CoMP transmission. The method includes: a terminal receiving from a base station control signaling which indicates to the terminal to perform channel information feedback, the control signaling including indication information about a plurality of CSI-RS resources for performing aggregation feedback; the terminal obtaining the plurality of CSI-RS resources based on the indication information to perform channel estimation and constructing a channel matrix according to a PDSCH transmission solution over a preset CSI reference resource, the correlation between the signal over the plurality of CSI-RS resources and the signal of a UERS port and the constructed channel matrix and transmitting the CSI to the base station. Also disclosed is a device for implementing the method.
