Communication apparatus and communication method

摘要

A communication quality managing unit acquires or calculates a communication quality of a received signal at a different counterpart communication apparatus. A terminal model identifying unit identifies a model of the different counterpart communication apparatus. A switchover table storing unit stores a table, in which a communication quality corresponding to a requirement for switchover of a communication mode is set, for each model of the different counterpart communication apparatus. A switching unit refers to the table on the basis of the communication quality and the model of the different counterpart communication apparatus to switch a setting of a communication mode for a transmitting signal 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 processes the transmitting signal to output the processed signal to a plurality of antennas, on the basis of the set communication mode.

1. A communication apparatus comprising:
a plurality of antennas; a quality managing unit for acquiring or calculating a communication quality of a received signal at a different counterpart communication apparatus; an identifying unit for identifying a model of the different counterpart communication apparatus; a storing unit for storing a plurality of tables, wherein each of the plurality of tables corresponds to a different one of a plurality of models of communication apparatuses, and wherein each of the plurality of tables identifies a communication quality corresponding to a requirement for switchover of a communication mode for the corresponding one of the plurality of models; a switching unit that
identifies one of the plurality of tables corresponding to the identified model of the different counterpart communication apparatus, andsets a communication mode, for a transmitting signal to the different counterpart communication apparatus, from among a non-spatial multiplexing mode and a spatial multiplexing mode, based on a communication quality identified in the identified table corresponding to the identified model of the different counterpart communication apparatus; and a transmitting unit for processing the transmitting signal to output the processed signal to said plurality of antennas on the basis of said set communication mode.
