DISTRIBUTED ANTENNA SYSTEM, WIRELESS COMMUNICATION METHOD, AND WIRELESS COMMUNICATION DEVICE

WIPO Patent Application WO/2024/023923

A1

This distributed antenna system is provided with a first communication device and a plurality of antennas for performing communication with a plurality of second communication devices by spatial multiplexing in accordance with a control by the first communication device. The first communication device is provided with: an extraction unit that extracts, from among the plurality of second communication devices, a plurality of candidate second communication devices which become candidates for performing spatial multiplexing; and an assignment unit that assigns communication opportunities to, from among the extracted plurality of candidate second communication devices, two or more candidate second communication devices that meet the conditions that the distance between the candidate second communication devices is not less than a first threshold and that an overlapping rate of each of the antennas assigned to the candidate second communication devices is less than a second threshold, as targets for performing communication by spatial multiplexing. Each of the antennas assigned to the two or more candidate second communication devices to which communication opportunities are assigned among the plurality of antennas performs spatial multiplex transmission to the two or more second communication devices.
