Method and device for transmitting channel state information

A method for transmitting CSI, comprising:

• sending, by a base station, control signaling to a user equipment to instruct the user equipment to feed back channel information, wherein the control signaling includes indication information of a plurality of CSI-RS resources for an aggregated feedback;
• and
• receiving, by the base station, CSI from the user equipment for the plurality of CSI-RS resources.

A user equipment, comprising:

• an interface module configured to receive control signaling, from a base station, to instruct the user equipment to feed back channel information, wherein the control signaling includes indication information of a plurality of CSI-RS resources for an aggregated feedback;
• a channel estimation module configured to perform channel estimation based on the plurality of CSI-RS resources obtained from the indication information and to construct a channel matrix according to a result of channel estimation;
• a CSI determination module configured to determine CSI according to a preset Physical Downlink Shared Channel, PDSCH, transmission scheme over a CSI reference resource, a correspondence relationship between signals over the plurality of CSI-RS resources and signals on UERS ports and the constructed channel matrix, and to instruct the interface module to transmit the CSI to the base station.
