摘要： Embodiments of the present invention provide an information transmission method, an access point, and a station. A channel resource of a wireless local area network is divided into multiple child resources in a frequency domain. The access point includes: a receiving unit, configured to receive resource status information sent by a station, where the resource status information indicates a busy/idle state of each child resource on the station; and an allocation unit, configured to allocate, according to the resource status information, the child resource used to transmit data between the access point and the station. In the embodiments of the present invention, a station sends resource status information to an access point, so as to report a busy/idle state of a child resource on the station to the access point. In this way, the access point can allocate, according to the busy/idle state of a child resource on the station, an appropriate resource for data transmission, thereby reducing a data transmission collision possibility.

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.
