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.
Claims12
A multiple antenna system “MAS” with multiuser “MU” transmissions “MU-MAS” comprising:
- a plurality of antennas or wireless transceiver devices “BTSs” (903) distributed throughout a coverage area, each BTS with a cell identifier “cell ID”;
- a plurality of wireless user devices “UEs” communicatively coupled to at least one of the BTSs (903) and distributed throughout the coverage area;
- and
- a spatial processing unit (901) configured to utilize precoding to combine N streams of information from M streams of bits to create a plurality of concurrent non-interfering downlink “DL” data links;
- and
- wherein the plurality of UEs maintain more than eight concurrent non-interfering DL and uplink “UL” links with more than eight BTSs throughout an entire coverage area of one or more BTSs within the same frequency band;
- and
- wherein M and N are integer numbers of more than 8.
A method implemented within a multiple antenna system “MAS” with multiuser “MU” transmissions “MU-MAS” comprising:
