COOPERATION TRANSMISSION METHOD USING A CODE BOOK DESIGNED BY MULTI CELLS IN A WIRELESS COMMUNICATION NETWORK AND THE WIRELESS COMMUNICATION SYSTEM THEREFOR, CAPABLE OF GENERATING A CODEBOOK FOR A MULTI CELL IN AN MIMO SYSTEM ENVIRONMENT
PURPOSE: A cooperation transmission method using a code book designed by multi cells in a wireless communication network and the wireless communication system therefor are provided to generate a multi cell code book in a plurality of base stations to perform cooperation communication through the multi cell code book in the base stations, thereby increasing performance of a multi cell MIMO(Multi Input Multi Output) system.;CONSTITUTION: A serving base station receives a PMI(Precoding Matrix Indication or Precoding Matrix Index) and average receiving power from a terminal(S301). The serving base station transmits the received PMI and the average receiving power to a cooperation base station(S303). The serving base station and the cooperation base station generate a multi cell code book using a shared single cell code book(S305). The serving base station and the cooperation base station are cooperated with a terminal by applying a precoding matrix that the received PMI indicates(S307).;COPYRIGHT KIPO 2010
