摘要： In some aspects, a method for configuring channel access parameters in a wireless communication system includes determining, at an access point, an enhanced distributed channel access (EDCA) parameter for a first subset of stations of a plurality of stations, the first subset of stations capable of transmitting multi-user uplink transmissions. The method further includes generating an information element including the EDCA parameter. The method further includes transmitting the information element such that the information element is decodable by the first subset of stations and not by a second subset of stations of the plurality of stations.

In one aspect, a method for wireless communication includes generating a clear to send message comprising a specific medium access control address (MAC) identifiable by a first subset of a plurality of wireless devices as instructing not to update an associated network allocation vector according to a duration field in the clear to send message. The specific MAC address is not identifiable by a second subset of the plurality of wireless devices such that the second subset of the plurality of wireless devices are instructed to update an associated network allocation vector according to the duration field. The method further includes transmitting the message, thereby reserving wireless communication access for the first subset of the plurality of wireless devices.

摘要： A method of controlling transmissions includes receiving, at a first wireless device, a packet from a second wireless device over a particular channel in a network. The method also includes determining a transmission power of the packet and determining a clear channel assessment threshold for the particular channel based at least in part on the transmission power. The method further includes deferring transmissions over the particular channel to the second wireless device based on the clear channel assessment threshold.

摘要： A method for configuring channel access parameters in a wireless communication system includes selecting an element identification (ID) from a plurality of element IDs. Each of the plurality of element IDs identifies an enhanced distributed channel access (EDCA) parameter set element comprising at least one channel access parameter for at least one subset of wireless devices in a group of wireless devices. The selected element ID is identifiable by wireless devices of the group of wireless devices and not identifiable by other wireless devices. The method further includes generating the EDCA parameter set element for setting the at least one channel access parameter for each wireless device in the at least one subset. The EDCA parameter set element includes the selected element ID. The method further includes transmitting the EDCA parameter set element to at least one wireless device in the at least one subset of wireless devices.
