Abstract
A first base station receives from a mobile terminal identification information indicating a combination of a weight coefficient for the first base station and a weight coefficient for a second base station, transfers the received identification information to the second base station, and performs precoding of a data signal to be transmitted to the mobile terminal by collaborative transmission, by using the weight coefficient for the first base station identified by means of latest identification information. The second base station receives the identification information from the first base station, and performs precoding of a data signal to be transmitted by collaborative transmission, by using the weight coefficient for the second base station identified by means of identification information obtained as latest identification information and different from that for the weight coefficient for the first base station used for precoding of the data signal.
