Systems and methods to coordinate transmissions in distributed wireless systems via user clustering

摘要

Disclosed is a multiuser (MU) multiple antenna system (MU-MAS). The system comprises one or more centralised units communicatively coupled to multiple distributed transceiver stations or antennas via a network the network consisting of wireline or wireless links or a combination of both which employed as a backhaul communication channel. The centralised unit transforming the N data streams into M precoded data streams. Each precoded data stream is a combination of some or all N data streams. The M precoded data streams are sent over the network to the distributed transceiver stations. The distributed transceiver stations simultaneously sends the precoded data streams over wireless links to at least one client device such that at least one client device receives at least one of the original N data streams.
