1. 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.

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.

23. 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. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 52)
