The invention discloses a wireless local area network communication method, related equipment and system. The method includes: a first access point sends an establishment message to multiple adjacent access points, wherein the establishment message is used to request establishment of a cooperative service set; An access point receives a response message fed back by a neighboring access point according to the establishment message; the first access point establishes a coordinated service set including the first access point and multiple second access points according to the received response message, Wherein, the second access point is an adjacent access point that has sent the response message; the first access point sends an acknowledgment message to multiple second access points, and the acknowledgment message includes an identity corresponding to the established coordinated service set, It is used to indicate that the second access point belongs to the coordinated service set corresponding to the identity. By implementing the method of the invention, the channel contention overhead during data interaction between access points can be reduced.
Description
technical field [0001] The present invention relates to the communication field, in particular to a wireless local area network communication method, related equipment and system. Background technique [0002] The IEEE 802.11 Working Group established the High Efficiency WLAN Study Group (HEW SG) in 2013, and established the 802.11ax Working Group (TGax) in 2014, preparing to introduce Orthogonal Frequency Division Multiple Access , OFDMA), scheduling and other new technologies. Since it works in an unlicensed frequency band, for an access point (Access Point, AP) using the 802.11ax standard protocol, cooperation between APs is particularly important. [0003] See figure 1 , figure 1 It is a schematic diagram of a scenario of a collaborative service set (Collaborative Service Set, CSS) in the prior art. The CSS consists of multiple Basic Service Sets (BSS). Since the BSSs can pre-negotiate the internal interaction mode of each BSS, the interaction between the AP and the ...
