CHANNEL RECONSTRUCTION METHOD, BASE STATION AND USER EQUIPMENT

摘要

The present invention discloses a channel reconstruction method for a downlink multi-antenna-multi-base-station with inconsistent antenna configuration. Firstly, a serving base station configures a user equipment. If antenna configuration of the multi-antenna-multi-base-station system is inconsistent, virtual antennas are introduced to a base station with fewer antennas in the system. A user equipment selects and feeds back indices of the virtual antennas and reconstructs channels of the multi-antenna-multi-base-station system to generate a consistent antenna configuration. Finally, the multi-antenna-multi-base-station system transmits a signal to the user equipment by adopting a transmission pre-processing scheme of the consistent antenna configuration. The present invention provides also a serving base station, a cooperative base station and a user equipment for realizing the channel reconstruction method. The present invention has advantages of large application range, simple implementation and better performance.
