The invention provides a communication method of a wireless local area network, a communication device of the wireless local area network, a station and an access point. The communication method of the wireless local area network comprises generating a first message frame which comprises number information of basic service sets of station statistics and CCA values corresponding to the basic service sets, and sending the first message frame to the access point. The number information of the basic service sets and the CCA values corresponding to the basic service sets are used by the access point to set a CCA value of the access point. According to the technical scheme, the access point can set the relative accurate CCA value and the relative accurate number of the basic service sets, so a communication conflict can be prevented from occurrence as far as possible, and the handling capacity of a system is indirectly improved.
