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.

Abstract: N time-frequency resources are determined by a first communications device. Any two of the N time-frequency resources are nonconsecutive in at least one of a time domain and a frequency domain; each of the N time-frequency resources is smaller than a time-frequency resource required for transmitting to-be-transmitted data, a sum of the N time-frequency resources is greater than or equal to the time-frequency resource required for transmitting the to-be-transmitted data and N is a positive integer greater than or equal to 2. First indication information is sent on M of the N time-frequency resources. The first indication information is used to indicate that the N time-frequency resources are used to send the to-be-transmitted data, M is a positive integer less than or equal to N. The to-be-transmitted data are sent on the N time-frequency resources so that time-frequency resource utilization is improved.

Abstract: A data transmission method, a communication device, and a data transmission system are disclosed. The method includes: determining to-be-transmitted data that needs to be sent to a network side device; before an initial transmission moment of transmitting the to-be-transmitted data to the network side device arrives, sending the to-be-transmitted data to a coordinating device; receiving the to-be-transmitted data sent by the target device; obtaining transmission parameter information; and when the initial transmission moment corresponding to the to-be-transmitted data arrives, sending the received to-be-transmitted data to the network side device based on the transmission parameter information. Therefore, when the target device needs to send the to-be-transmitted data to the network side device, the coordinating device may help the target device perform initial transmission of the to-be-transmitted data, thereby increasing a success probability of initial transmission, and further improving link reliability.
