1. An apparatus for wireless communication in a network, the apparatus comprising:
(a) a wireless communication circuit, as a wireless station (STA) operating under IEEE 802.11 as either an Access Point (AP) or a non-AP STA, is configured for wirelessly communicating packets 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) 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 of broadcasting a type of sharing frame containing sharing information which carries specific parameter settings to share with other STAs comprising:
(i) a STA communicates an update sequence to indicate the version of its specific parameter settings;
(ii) a STA operating as a first STA broadcasts a sharing frame carrying an update sequence and specific parameter settings to share with other STAs on the WLAN;
(iii) receiving said sharing frame by said second STA as received from said first STA, and recording the update sequence of the first STA by said second station; and
(iv) reporting a most recent update sequence as received from said first STA, by said second station broadcasting a sharing frame including update sequence information.
