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.

Abstract: A receiving station simultaneously receives a plurality of procedure protocol data units (PPDUs) from a sending station on a plurality of channels, where the plurality of PPDUs includes a plurality of media access control protocol data unit (MPDU) sets, and each of the plurality of MPDU sets includes at least a copy of a start MPDU. The receiving station sends a block acknowledgment on one or more channels of the plurality of channels, where the block acknowledgment includes acknowledgment information, and the acknowledgment information indicates acknowledgment of MPDUs successfully received on the plurality of channels and transmission quality of each of the plurality of MPDU sets.
