Abstract
A base station communicating using multiple antennas includes a direction-of-arrival (DOA) estimation unit configured to estimate a direction of arrival based on a signal from a mobile station and to output direction-of-arrival information regarding the estimated direction of arrival; a DOA information multiplexing unit configured to multiplex the direction-of-arrival information from the direction-of-arrival estimation unit with a shared data channel to be transmitted to the mobile station; and an antenna weight multiplying unit configured to multiply a signal to be transmitted to the mobile station and including the shared data channel multiplexed with the direction-of-arrival information by antenna weights obtained based on the direction-of-arrival information from the direction-of-arrival estimation unit.
