Abstract

The invention provides a communication method and a communication device in a wireless local area network, an access point and a site. The communication method comprises the following steps: generating a message frame, wherein the message frame contains an OFDMA random access contention period field which represents that a site supporting a UL OFDMA mechanism can contend to access a channel in a contention period indicated by the OFDMA random access contention period field; and sending the message frame to the site. According to the technical scheme, the time for the site to use the OFDMA Back-off mechanism can be defined, and then application of the OFDMA Back-off mechanism can be guaranteed, so as to improve the high spectrum utilization efficiency and indirectly improve the system throughput.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a communication method of a wireless local area network, a communication device of a wireless local area network, an access point and a station. Background technique [0002] In May 2013, 802.11 established a next-generation Wi-Fi technology research group HEW (High efficiency WLAN, high-efficiency wireless local area network), that is, 802.11ax. The main research points are to improve the throughput of existing Wi-Fi technology and increase the spectrum Effective utilization of efficiency, improvement of user experience and service quality QoE (Quality of Experience), and realization of a more dense communication environment than existing Wi-Fi technologies. [0003] In the 802.11ax standard, it is stipulated that OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) technology will be used to enable multiple users to...
