Claim 19:
20. A method of wireless communication in a network, the method comprising:
(a) a wireless communication circuit having a processor configured for executing a protocol for a priority-capable wireless station (STA) to communicate over a channel with other wireless stations (STAs), which are either APs or non-AP STAs, on a wireless local area network (WLAN) in which Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is applied;
(b) operating said priority-capable STA with EDCA functions to operate with multiple predetermined sets of single EDCA or Multiple-User (MU) EDCA operating parameters for each access class (AC) of EDCA for providing a range of priority levels, wherein each predetermined set of operating parameters provides different levels of nominal access time for use by the STA at different periods of time when contending for said at least one channel;
(c) wherein said priority-capable STA determines from the data that a priority period is required for transmission, and switches to utilizing a predetermined higher-priority set of single EDCA or Multiple-User (MU) EDCA operating parameters in a given AC, from said multiple predetermined sets of single EDCA or Multiple-User (MU) EDCA operating parameters, when the STA needs to speed up channel access; and
(d) wherein said priority-capable STA utilizes a predetermined lower-priority set of EDCA operating parameters in a given AC, from said multiple predetermined sets of single EDCA or Multiple-User (MU) EDCA operating parameters, when the STA needs to slow down channel access for lower priority traffic and for keeping channel access equitable between stations in the network.
