Claim 31:
32. An apparatus for wireless communication in a network, the apparatus comprising:
(a) a wireless communication circuit, as a wireless station (STA) operating as either an Access Point (AP) or a non-AP STA, is configured for wirelessly communicating 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 packets carry frames;
(b) a processor coupled to said wireless communication circuit for operating on the WLAN as a STA;
(c) a non-transitory memory storing instructions executable by the processor for communicating with other STAs; and
(d) wherein said instructions, when executed by the processor, perform one or more steps comprising:
(i) utilizing non-zero backoff procedures for channel contention when said STA supports non-zero backoff procedure, and utilizing legacy backoff procedure for channel contention when said STA does not support non-zero backoff procedures;
(ii) setting an AIFS time for an AC shorter, as a short AIFS time, when using a non-zero backoff procedure, than the length of an AIFS time utilized for that AC when using the legacy backoff procedure toward providing said non-zero backoff procedure with a higher probability of accessing the channel earlier than STAs using said legacy backoff procedure; and
(iii) wherein said station operating in the role of an AP reuses an Enhanced DCF Channel Access (EDCA) parameter set by communicating the EDCA parameter set to its associated STAs for setting said non-zero backoff procedure.
