Abstract:
A method for transmitting and receiving a signal of a terminal, according to an embodiment of the present invention includes the steps of: receiving a signal from a base station; calculating an expected value of the signal to interference plus noise ratio (SINR) based on the received signal; and choosing a beamforming method based on the expected value of SINR. The present invention can provide a method and an apparatus which apply adaptive ICIC in CoMP environment so as to maximize WSR with reduced complexity of calculation, thus having a performance comparable to that determined by the conventional method, and providing the user with a smooth communication environment with improved quality. Furthermore, a terminal communicating with a base station chooses a desirable beamforming technique with reduced complexity so as to decrease the complexity of the system and to provide higher power efficiency with a faster calculation speed. Besides, it is possible for a base station to readily choose the user group and the beamforming technique group with the optimum communication environment.
