PURPOSE: An adaptive bit allocation method and a device thereof for a multi-cell joint processing system sharing data and channel state information in a limited feedback environment are provided to further improve the performance of the system when a user is adjacent to a cell edge. ;CONSTITUTION: A control unit determines an actual channel vector and a quantized channel vector (215). The control unit determines a vector which maximizes quantization accuracy (220). The control unit determines a phase difference between base stations. The control unit determines a bit combination which maximizes quantization accuracy using the vector which maximizes quantization accuracy and the phase difference (230,235). A transmission unit transmits the determined bit combination to the base station (240).;COPYRIGHT KIPO 2013;[Reference numerals] (210) Perform channel measurement; (215) Determine an actual channel vector; (220) Determine a quantized channel vector; (225) Determine a quantization error and a phase difference between base stations; (230) Determine a vector which maximizes quantization accuracy; (235) Determine a bit combination which maximizes quantization accuracy; (240) Transmit the determined bit combination to the base station; (AA) Start; (BB) End
