摘要： A method for indicating a transmission opportunity (TXOP) duration in a wireless communication system includes generating, by a TXOP holder, a physical layer protocol data unit (PPDU). The PPDU includes a High Efficiency Signal field A (HE-SIGA), and the HE-SIGA includes a TXOP duration field. The TXOP duration field is used to indicate to other stations a remaining time for using a channel by a station. The TXOP duration field includes a first part which indicates a granularity used, and a second part which indicates the TXOP duration using the granularity indicated by the first part. The TXOP holder sends the generated PPDU.

摘要： The present disclosure provides a data transmission method and device. The method includes sensing, by a station, whether a channel allocated by an access point associated with the station is occupied, before obtaining a downlink scheduling phase. If the channel is not occupied, sending, by the station, channel clear signaling to the access point, where the channel clear signaling includes a first identifier used for identifying the station and a second identifier used for identifying the access point. The method also includes receiving, by the station in the downlink scheduling phase, data transmitted by the access point. The present disclosure ensures normal data transmission.

摘要： Embodiments of the present invention provide a method and an apparatus for transmitting signaling. The method includes: modulating, by using a binary phase shift keying BPSK manner of rotation by a first angle, at least partial signaling information carried in at least one signaling symbol in a signaling field of a data packet, to obtain modulated signaling information, where the first angle is not equal to 0 degrees or 90 degrees; and sending, to a receive end, the data packet that carries the modulated signaling information. In the embodiments of the present invention, the signaling field of the data packet is modulated by using a modulation manner different from a conventional modulation manner, so that a data packet format corresponding to such a modulation manner can be distinguished from a conventional data packet format.
