Abstract
Systems and methods are described for exploiting inter-cell interference to achieve multiplexing gain in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”). For example, a MU-MAS of one embodiment comprises a wireless cellular network with multiple distributed antennas operating cooperatively to eliminate inter-cell interference and increase network capacity exploiting inter-cell multiplexing gain.
Claims2
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;
- 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 BTSs and the UEs within the same frequency band.

A method implemented within a MU-MAS comprising:
- distributing a plurality of BTSs throughout a coverage area without cells, all sharing the same cell ID;
- communicatively coupling a plurality of UEs to the BTSs;
- and
- exploiting interference among the BTSs to create a plurality of concurrent non-interfering DL or UL data links, including control channel links, between the BTSs and the UEs within the same frequency band.
