1. A multiple antenna system (MAS) with multiuser (MU) transmissions (“
- MU-MAS”
) comprising;
a plurality of distributed antennas or wireless transceivers distributed throughout a cell or coverage area and communicatively coupled to one or a plurality of spatial processing units via a wireline or wireless network;
a plurality of user equipment devices (UEs) communicatively coupled to the distributed antennas via a plurality of wireless links;
wherein each of the plurality of UEs receives the same cell ID; and
the distributed antennas cooperatively send or receive a plurality of signals that intentionally interfere to create a plurality of non-interfering data links with the UEs at the same time and within the same frequency band.
