Wireless access point, terminal device, and method for waking up terminal device by wireless access point

A method for waking up a terminal device, the method comprising:

• operating, by a wake-up radio (WUR) radio frequency circuit of the terminal device, in a receive-only mode on one specified channel;
• waking up, by the WUR radio frequency circuit, a primary radio frequency circuit of the terminal device if the WUR radio frequency circuit receives a wake-up frame and the terminal device is a to-be-woken-up terminal device, wherein the wake-up frame comprises an identifier of the to-be-woken-up terminal device;
• operating, by the primary radio frequency circuit, on an operating channel of the primary radio frequency circuit after being woken up;
• and
• receiving, by the primary radio frequency circuit, information about the specified channel of the WUR radio frequency circuit on the operating channel of the primary radio frequency circuit.

A method for waking up a terminal device implemented by a wireless local area network (WLAN) device, the method comprising:

• sending information about a specified channel on an operating channel;
• sending a wake-up frame on the specified channel, wherein the wake-up frame comprises an identifier of a terminal device that is to be woken up;
• and
• sending a WLAN frame on the operating channel.

A wireless local area network (WLAN) device, comprising:

• a transceiver;
• and
• a processor coupled to the transceiver and configured to:
• send, via the transceiver, information about a specified channel on an operating channel;
• send, via the transceiver, a wake-up frame on the specified channel, wherein the wake-up frame comprises an identifier of a to-be-woken-up terminal device;
• and
• send, via the transceiver, a WLAN frame on the operating channel.
