Communication method and device for wireless local area network and communication terminal

Abstract

The invention provides a communication method and device for a wireless local area network and a communication terminal. The communication method for the wireless local area network comprises a step of receiving a first type of wake-up frames, wherein the first type of wake-up frames include timing synchronization functions wherein the timing synchronization functions in the first type of wake-upframes are used for indicating time synchronization with associated access point equipment, and the timing synchronization functions in the first type of wake-up frames are consistent with the timingsynchronization functions in a beacon frame broadcast by the access point equipment. According to the technical scheme, work station equipment is prevented from being periodically awakened to monitorTIM (Traffic Indication Map) information in the beacon frame and being accessed to a channel in a competitive mode to obtain cached downlink data, the power consumption loss of the work station equipment is reduced, the frequency spectrum utilization efficiency is improved, and meanwhile, the time synchronization between the work station equipment and the access point equipment is realized.

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 and a communication terminal. Background technique [0002] In July 2016, 802.11 established the next-generation Wi-Fi (Wireless Fidelity, Wireless Fidelity) technology research group WUR (Wake up Receiver), which is mainly used in the Internet of Things, with the purpose of saving equipment power as much as possible. consumption. [0003] A wake up frame is defined in the WUR research group, in which the data frame receiver of the device can be in a dormant state, and when the wake up frame receiver of the device receives the wake up frame, it will wake up the data frame receiver It can be seen that the purpose of defining the Wake up frame is to help the device save power consumption. [0004] In the Wi-Fi infrastructure in the related art, the time s...

Problems solved by technology

[0005] However, since the power consumption of a workstation device receiving wake up frames is much lower than that of receiving beacon frames, if a workstation device that supports receiving wake up frames is in a dormant state, it still needs to be woken up periodically to receive The time synchronization of the beacon frames will undoubtedly cause unnecessary power consumption loss, and it obviously does not meet the needs of WUR communication technology.
