METHOD FOR SYNCHRONIZING FREQUENCY FOR COORDINATED MULTIPOINT TRANSMISSION

摘要

PURPOSE: A method for synchronizing frequencies for coordinate multipoint transmission is provided to reduce frequency offset deviation between transmission points by implementing coordinate point transmission after synchronizing frequencies using frequency synchronization information. CONSTITUTION: A signal transmitted from a base station is received(S210). The distortion of a wireless channel is measured using a reference signal included in the received signal(S220). The channel equalization and frequency error component of the received signal are compensated(S230). The signal in which frequencies are synchronized is demodulated and decoded for securing data(S240).
