A METHOD AND APPARATUS FOR TRANSMITING RECORDING INFORMATION FOR UPLINK TRANSMISSION IN MULTI BASE STATION MIMO SYSTEM

摘要

A PMI combination ratio (PCR) being used for generating a uplink precoding matrix W is transmitted by a base station to a mobile station. Using the PCR, a PMI maximizing transmission performance and PMIMin minimizing interference to a neighboring base station are combined into the uplink precoding matrix W. Averall operations of a system can be simplified and the load of calucation for generating the uplink precoding matrix W in the mobile station can be reduced, because the PCR is provided by the base station.
