Abstract: Various embodiments provide a data transmission method and apparatus. In those embodiments, a first device sends first indication information in a first frequency band, where the first indication information is indicative of a resource in a second frequency band, used by the first device and the second device to perform data transmission. In those embodiments, the first device performs, based on the scheduling information, data transmission with the second device, using the resource in the second frequency band. Those embodiments can schedule a device based on a plurality of frequency bands to perform data transmission. In this way, a larger bandwidth is used, a throughput rate is increased, and system performance is improved.

Abstract: A method for establishing a communication connection between a station (STA) and an access point (AP). The method includes: receiving, by the AP, request frames sent by N STAs to the AP, and after the AP receives the request frames sent by the N STAs, contending for a channel by the AP and sending one response frame to M STAs, where the response frame includes identifiers of the M STAs and M responses to the M STAs. Each of the identifiers of the M STAs corresponds to one of the M responses, wherein 2≤M≤N.

Abstract: Embodiments of the present disclosure disclose a method and an apparatus for transmitting a trigger frame in a wireless local area network. The method for transmitting a trigger frame in a wireless local area network includes: generating, by an access point, a trigger frame carrying a target media access control MAC function, where the trigger frame includes indication information, the indication information is used to instruct a first station to send a MAC frame corresponding to the target MAC function, and the indication information is used to instruct a second station not to perform the target MAC function; and sending, by the access point, the trigger frame. In the present disclosure, the indication information is used to instruct the first station to send the MAC frame corresponding to the target MAC function without limiting the second station, so that data sending manners of the first station and the second station can be flexibly controlled.

Abstract: An access point generates a beacon frame that carries a trigger frame information element comprising sending information of a trigger frame for indicating a sending period of the trigger frame; and sends the beacon frame. In this case, the station switches to an active state, and receives the trigger frame by listening to the channel, and the station performs uplink transmission according to indication of the trigger frame after receiving the trigger frame. In this way, when signaling overheads are not increased and reliability is ensured, a station can learn of a sending time of a trigger frame, and the station remains in a receiving state in an appropriate period of time.
