Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] Various embodiments of the present invention can be applied to a wireless local area network (English: Wireless Local Area Network, WLAN). Currently, WLAN adopts the Institute of Electrical and Electronics Engineers (English: Institute of Electrical and Electronics Engineers, abbreviated: IEEE) 802.11 series. A WLAN can include multiple Basic Service Sets (English: Basic Service Set, abbreviated: BSS). The network nodes in the BSS are stations, and the stations include access point stations (English: Access Point, abbreviated: AP) and non-access Point-type stations (English: None Access Point Station, referred to as: Non-AP STA), each basic service set can include an AP and multiple Non-AP STAs associated with the AP. It shou...

Abstract

Embodiments of the present invention provide a wake-up frame sending method and device. The wake-up frame sending method is applied to the first node, and the NAV of the first node is set on the first channel. The wake-up frame sending method includes: when the second channel is detected to be idle, ignore the NAV, and the first node's The master transceiver sends a wake-up frame to the second node on the second channel. In the present invention, when the first channel of the main transceiver of the second node is different from the second channel of the wake-up receiver of the second node, the first channel is listened to by default, and the frame of the first node on the first channel Set NAV, but when the second channel is idle, it can still send a wake-up frame to the second node on the second channel, and then wake up the main transceiver of the second node, so that the main transceiver of the second node can be woken up in time when the second channel is idle. transceiver effect.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for sending a wake-up frame, a method and a device for sending a first frame after a node wakes up. Background technique [0002] When the first node needs to send data to the second node, it usually needs the second node to listen to the first node. In order to save the monitoring power consumption of the main transceiver in the second node, a low power consumption wake up receiver (English: low power wake up receiver, referred to as: LP-WUR). When the first node needs to send data to the second node, it first sends a wake-up frame to the second node, and the wake-up receiver of the second node wakes up the main transceiver in the second node after receiving the wake-up frame, and the awakened main transceiver The machine communicates with the first node. [0003] Usually, the main transceiver of the first node will listen to the channel where the main transceiver of...
