Abstract: An access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.

Abstract: This application provides a channel sensing method, a related device, and a system. The method includes: performing, by a sending device, LBT; and sending, by the sending device, a first channel occupancy signal after the LBT succeeds, where the first channel occupancy signal is used to indicate, to a first receiving device that receives the first channel occupancy signal, a to-be-protected channel occupancy time on a channel occupied by the sending device after the LBT succeeds. According to the foregoing solution, a collision between devices that need to perform transmission can be avoided, thereby improving communication efficiency.
