Abstract

An adaptive array base station (1000) controls transmission power so that a downlink transmission signal power is increased only at a symbol point of the downlink transmission signal in a communication channel for each of a terminal of user (1) and a terminal of user (2) which are spatially-multiplexing-connected. Accordingly, it is possible to prevent a case that a transmission power to each of the user terminals is an interference component to each other. This improves downlink reception performance in each of the user terminals.
