BASEBAND PROCESSING DEVICE FOR WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION SYSTEM

摘要

Embodiments of the present invention provide a baseband processing device, system, and method for a wireless communication system. The device comprises a first unit and a second unit for implementing different baseband processing functions. The second unit is used for generating a precoding matrix of a downlink CoMP user, generating precoding control information according to the precoding matrix, and sending the precoding control information to the first unit. The first unit is used for receiving the precoding control information sent by the second unit, and performing downlink joint baseband processing for downlink CoMP user data in downlink user data according to the precoding control information, so as to generate jointly sent baseband data for wireless sending. The first unit is further used for sending uplink CoMP user data in uplink user data to the second unit. The second unit is further used for completing uplink joint baseband processing for the uplink CoMP user data sent by the first unit. The foregoing technical solutions can reduce a transmission bandwidth between based band units and obtain a system capacity gain at the same time.
