Abstract
A system and method for providing spatial reuse in a wireless network for communicating compressed and uncompressed audio/video is disclosed. A bandwidth reservation request for data communication with a receiver to a coordinator is transmitted. A first response indicating availability of the receiver for the data communication is received. A channel is listened to by a station for channel busy indication (CBI) messages transmitted by other stations in the wireless network. A local channel occupation report comprising data indicative of one or more time periods during which one or more other stations in the wireless network are scheduled to transmit data messages is transmitted to the coordinator. A second response comprising data indicative of one or more allocated channel time slots is received. Audio and/or video (A/V) data is transmitted to the receiver during the allocated channel time slots.
