摘要： A Tx beamforming method for multi-sector cooperative transmission in a multi-antenna system includes determining a transmission mode of sector boundary users according to a channel condition; determining a multi-sector cooperative Tx beam for supporting multiple users, based on the transmission mode of the user; determining a user combination for multi-sector cooperative beamforming by considering the determined multi-sector cooperative Tx beam; and performing sector cooperative Tx beamforming with the determined user combination. Thus, the overall system capacity can be enhanced.

摘要： In a wireless communication system, at least one sounding subchannel determining parameter is transmitted from a sounding signal receiving apparatus to a sounding signal transmitting apparatus. A sounding subchannel for the sounding signal transmitting apparatus is allocated according to the sounding subchannel determining parameter. A sounding signal is received from the sounding signal transmitting apparatus over the allocated sounding subchannel. The sounding subchannel determining parameter is determined for allocating a sounding subchannel considering a frequency correlation.
