APPARATUS AND METHOD FOR PERFORMANCE ENHANCEMENT IN OPEN LOOP MULTI CELL MIMO SYSTEM
Abstract:
An apparatus and a method for operating a Mobile Station (MS) in a wireless communication system are provided. The method includes receiving a threshold for a gap of an average Receive (Rx) power between a neighboring Base Station (BS) and a serving BS, transmitting to the serving BS, identification information of a BS having the average power greater than a first value, receiving information of a BS involving joint processing generated using information of the BS having the average power greater than the first value, feeding Precoding Matrix Index (PMI) information of the BS involving the joint processing, back to the serving BS, receiving information indicating a PMI operation mode of the MS, from the serving BS, and determining a PMI operation mode according to the information indicating the PMI operation mode of the MS.
