Abstract:
A signal transmission method and apparatus of a base station is provided for increasing transmit power by compensating a phase value of the signal transmitted through multiple antennas based on signal reception status information fed back from a terminal in a wireless communication system. The signal transmission method includes transmitting a signal to at least one terminal through the multiple antennas; receiving signal reception status information transmitted by the at least one terminal; calculating a compensation phase based on the signal reception status information; applying the compensation phase to next signal to be transmitted through the multiple antennas; and transmitting the next signal to the at least one terminal through the multiple antennas.
