Distributed antenna system, wireless communication method and wireless communication apparatus

Abstract

A distributed antenna system including a first communication device and a plurality of antennas that communicates with a plurality of second communication devices by spatial multiplexing under control of the first communication device, the first communication device including an extraction unit that extracts a plurality of candidate, second communication devices that is candidates for spatial multiplexing among the plurality of second communication devices; and an allocation unit that allocates communication opportunities, as targets for communication by spatial multiplexing, to two or more candidate, second communication devices from among the plurality of extracted candidate, second communication devices that satisfy a condition that a distance between the candidate, second communication devices is equal to or greater than a first threshold and an overlap ratio of each antenna allocated to each candidate, second communication device is less than a second threshold, in which each antenna allocated to the two or more candidate, second communication devices to which the communication opportunities have been allocated among the plurality of antennas performs spatial multiplexing transmission with respect to the two or more candidate, second communication devices.
