Document Type and Number:
WIPO Patent Application WO/2023/162177
Kind Code:
A1
Abstract:
Provided is a wireless communication method in a distributed antenna system comprising a base station and a plurality of antennas for performing communication with one or more terminal stations by spatial multiplexing in accordance with control by the base station, each of the plurality of antennas including a plurality of sub-arrays. The base station allocates a plurality of sub-arrays of different antennas to each of one or more candidate terminal stations as the subject for communication by spatial multiplexing using two or more sub-arrays among the plurality of sub-arrays. The plurality of sub-arrays allocated to the candidate terminal station perform spatial multiplexing transmission with respect to the candidate terminal station.
