COMMUNICATION APPARATUS AND COMMUNICATION METHOD

摘要

A setting unit (45) sets the communication mode, which is for one or more other communication apparatuses each of which is the other end of communication, to a non-spatial multiplexing mode or to a spatial multiplexing mode. The setting unit (45) switches, based on the capacity of the communication system including the local apparatus and the one or more other communication apparatuses each of which is the other end of communication, the setting of the communication mode, which is for the one or more other communication apparatuses each of which is the other end of communication, from the non-spatial multiplexing mode to the spatial multiplexing mode. A transmitting unit (13) processes, based on the communication mode as set, and outputs the transport signals, which are to be transmitted to the one or more other communication apparatuses each of which is the other end of communication, to a plurality of antennas (10, 11).
