Abstract
A multiple antenna system (MAS) with multiuser (MU) transmissions (“MU-MAS”) exploiting inter-cell multiplexing gain via spatial processing to increase capacity in wireless communications networks.
Claims39
A multiple antenna system (MAS) with multiuser (MU) transmissions (MU-MAS) comprising:
- a plurality of antennas or wireless transceiver devices (BTSs) distributed throughout a coverage area without cells, all sharing the same cell identifier (cell ID);
- a plurality of wireless user devices (UEs) communicatively coupled to the BTSs;
- the MU-MAS chooses a first subset of BTSs for downlink and uplink data communications based on the spatial diversity between the UEs and BTSs;
- and
- a spatial processing unit exploits interference among the BTSs to create a plurality of concurrent non-interfering downlink (DL) or uplink (UL) data links, including control channel links, between the first subset of BTSs and the UEs within the same frequency band.
