Abstract
A technique is disclosed to schedule frame transmissions in a wireless network. The network includes a plurality of stations configured to communicate on the same frequency channel with a plurality of access points. A central controller examines the transmission characteristics between the various stations and access points and identifies frames that may be simultaneously transmitted by a subset of the access points to their intended stations.
Claims52
A wireless network, comprising:
- a plurality of M access point transceivers;
- a plurality of N stations, wherein each station can communicate with all or a subset of the M access point transceivers;
- and
- a central controller coupled to the plurality of M access point transceivers, wherein the central controller is configured to examine transmission characteristics between a subset of the stations and a subset of the multiple antenna elements for each access point transceiver, and based upon the transmission characteristics identify frames that may be scheduled for simultaneous transmission.
A method of scheduling frame transmissions in a wireless network, wherein the wireless network includes a plurality of M access points, and a plurality of N stations, wherein each station can communicate with all or a subset of the M access points, comprising:
- receiving a set of frames for transmission to intended stations within the plurality of N stations;
- examining transmission characteristics between a subset of the stations and a subset of the antenna arrays for the access points;
- and
- based upon the transmission characteristics, identifying frames within the set of frames that may be simultaneously transmitted.
