Abstract: An access point in a random access wireless network is presented, which performs medium access control for transmissions from a plurality of stations to the access point using a carrier sense multiple access protocol. The CSMA protocol is based on the access point having a variable sensitivity level to detecting other transmissions on a wireless channel in order to avoid data collisions. In a dense network environment, the sensitivity level can be reduced to avoid detecting transmissions to other access points, and thus improve area efficiency.

Abstract: When contending for access to a radio channel (for example CSMA/CA in Wi-Fi), an apparatus selects a first clear channel assessment (CCA) threshold that is higher than a minimum; determines to temporarily use a second CCA threshold that is lower than the first CCA threshold; and based on this determination it selects the second CCA threshold for a specified time period. In one embodiment this determination is based on the apparatus' use of a spectrum relative to a threshold usage level which may be calculated as a number of successful transmissions by the apparatus on the spectrum over a predefined time period; and/or as a deferring time experienced by the apparatus with respect to the spectrum over a predefined time period. In an embodiment the specified time period comprises a backoff time, and the determination to temporarily use the second CCA threshold is triggered by a periodic timer.

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.
