Abstract: Example communication methods and apparatus are described. One example communication method includes receiving first indication information by a first communications device from a network device, where the first indication information indicates a first resource for sidelink communication. The first communications device sends the first data to a second communications device. The first communications device receives second indication information from the network device, where the second indication information is used to determine a second resource for transmitting feedback information. The first communications device receives feedback information of the first data from the second communications device.

Abstract: A third terminal receives control information from a first terminal, where the control information indicates a first resource and a second resource, the first resource carries first data corresponding to the control information, and the second resource is a sending resource reserved by the first terminal; the third terminal determines that the second resource meets a reselection condition; and the third terminal sends indication information to the first terminal, where the indication information indicates to reselect the second resource. When determining that a resource conflict exists in the second resource, the third terminal can indicate the first terminal in time to reselect the second resource, to prevent the first terminal from continuing to use the second resource to send data.

Abstract: In various embodiments, 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.
