Abstract: A method and apparatus for coordinated communication between multiple access points, and a storage medium are disclosed. The method includes: A first access point (AP) sends a coordinated frame to an AP in a coordinated group. The coordinated frame indicates at least one AP in the coordinated group and the first AP to perform a coordinated operation within an effective time period. The coordinated group includes a plurality of APs operating on the same channel. The first AP is an AP that obtains an access opportunity for the channel in the coordinated group. A time length of the effective time period exceeds a time length of a transmit opportunity (TXOP). According to this application, channel utilization can be improved.

Abstract: A wireless access point, a terminal device, and a method for waking up a terminal device by a wireless access point. The terminal device includes a primary radio frequency circuit and a wake-up radio (WUR) radio frequency circuit. The WUR radio frequency circuit only receives a radio signal and operates on a specified channel. If the WUR radio frequency circuit receives a wake-up frame on the specified channel and the terminal device is a to-be-woken-up terminal device, the WUR radio frequency circuit wakes up the primary radio frequency circuit. The wake-up frame includes an identifier of the to-be-woken-up terminal device. The primary radio frequency circuit operates on an operating channel of the primary radio frequency circuit after being woken up.
