Abstract
A wireless network having one or more access points and one or more stations may improve spectrum efficiency for uplink transmissions by assigning a plurality of stations to a channel (or subchannel), each with a different priority. A channel may be assigned to a first station with the first priority, a second station with a second priority, and so on (e.g., instead of assigning the channel to just one station). An access point may transmit information indicative of the channel assignments, priorities, and other information used by stations to perform uplink transmissions. If a station with the highest priority receives the data from the access point, it may start transmission. A station with a lower priority may listen, during a listening period, to the same channel and determine whether the higher priority station started transmission during the listening period. If the higher priority station did not start transmission during the listening period, the lower priority station may transmit uplink data to the access point.
