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.

Abstract

The present invention provides a communication method, a communication device, and a communication terminal of a wireless local area network, wherein the communication method of the wireless local area network includes: receiving a first type of wake-up frame, and the first type of wake-up frame contains time synchronization parameters, wherein the first type The time synchronization parameter in the type wake-up frame is used to indicate to maintain time synchronization with the associated AP device, and the time synchronization parameter in the first type wake-up frame is consistent with the time synchronization parameter in the beacon frame broadcast by the AP device. Through the technical scheme of the present invention, it is avoided that the workstation equipment periodically wakes up and listens to the TIM (Traffic Indication Map, data to be transmitted information indication map) information in the beacon frame through competition to access the channel to obtain the cached downlink data, reducing the The loss of power consumption of the workstation device improves spectrum utilization efficiency, and at the same time, realizes time synchronization between the workstation device and the access point device.

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...
