Abstract:
Provided are a method and device for feeding channel state information back. A terminal performs measurement on one or more groups of measurement resources according to signaling transmitted from a base station and/or its own assumption to obtain a measurement result corresponding to each group of measurement resources. The terminal calculates, according to the signaling and/or its own assumption and the measurement results, CSI on DMRS ports and/or DMRS port groups corresponding to each group of measurement resources. The terminal feeds part of or all calculated CSI back to the base station. Accordingly, the problem in the related art that in the process of using a CoMP technology to reduce interference of cell-edge users by a coordination of multiple adjacent base stations or points, the CSI fed back by the terminal has a low accuracy and a poor flexibility is solved, implementing technical effects of improving the accuracy and flexibility of the CSI fed back by the terminal.
