Title:
COMMUNICATION APPARATUS AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/087065
Kind Code:
A1
Abstract:
A communication quality managing unit (36) acquires or calculates the communication quality of a signal received at another communication apparatus that is the other end of communication. A terminal type determining unit (41) determines the type of the other communication apparatus that is the other end of communication. A switching table storing unit (39) stores a table in which the communication quality, which is a condition for switching communication modes, is defined for the type of each other communication apparatus that is the other end of communication. A switch unit (38) refers, based on the communication quality and type of the other communication apparatus that is the other end of communication, to the table to switch the setting of communication mode for transport signals from a non-spatial multiplexing mode to a spatial multiplexing mode or from the spatial multiplexing mode to the non-spatial multiplexing mode. A transmitting unit (13) processes, based on the communication mode as set, and outputs the transport signals to a plurality of antennas (10, 11).
