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 radio access network (RAN) 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);
- wherein the RAN is configured to choose a first subset of BTSs for downlink and uplink data communications based on the spatial diversity between a plurality of user equipment devices (UEs) and BTSs;
- and
- wherein the RAN is configured to exploit interference among the BTSs to create a plurality of concurrent non-interfering downlink (DL) or uplink (UL) data links between the first subset of BTSs and the UEs within the same frequency band.
1 more element
A method implemented within a radio access network RAN comprising:
- distributing a plurality of antennas or wireless transceiver devices (BTSs) throughout a coverage area without cells, all sharing the same cell ID;
- communicatively coupling a plurality of user equipment devices (UEs) to the BTSs;
- the RAN choosing a first subset of BTSs for downlink and uplink data communications based on the spatial diversity between the UEs and BTSs;
- and
- the RAN exploiting interference among the BTSs to create a plurality of concurrent non-interfering DL or UL data links between the first subset of BTSs and the UEs within the same frequency band.
