BASE STATION DEVICE, MOBILE COMMUNICATION SYSTEM, CONTROL METHOD FOR BASE STATION DEVICE, AND COMPUTER-READABLE MEDIUM

摘要

In one embodiment of the present invention, a base station (1) is configured to carry out signal processing that includes precoding in order to generate a plurality of time region signals that are supplied to a plurality of transmission antennas. In addition, the base station (1) is configured to enable the use of a plurality of precoding matrices in a first wireless resource that is defined by time and/or frequency, and to limit the use of a precoding matrix subset in a second wireless resource that is different from the first wireless resource, said precoding matrix subset corresponding to a portion of the plurality of precoding matrices.
