Method and apparatus for controlling cooperating transmission for downlink signal in a wireless telecommunications network

摘要

Method and apparatus for controlling the BS cooperating Horn and at least one serving BS to perform in concert the downlink data communication with the MS in a wireless telecommunications network based on the CO-MIMO techniques. To obtain the MIMO downlink channel information between the MS and cooperating BS and between the MS and the serving BS, the method, the downlink signal precoding information between the MS and cooperating BS and between the MS and the serving BS It will be determined according to the channel information, from the well as carried out in cooperation with the MS downlink MIMO data communications based on the downlink signal precoding information.
