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.

Abstract: Embodiments of the present invention disclose a state switching method and apparatus. The state switching method includes: receiving, by a first network node, a preset frame sent by a second network node, where the preset frame includes indication information used to indicate an on/off state of a main transceiver and/or a wake up receiver of the first network node immediately, after a specified time point, or within a specified time period; and controlling, by the first network node based on the indication information, to switch an on/off state of the main transceiver and/or the wake up receiver of the first network node. According to the embodiments of the present invention, energy is saved by using a preset frame to indicate an on/off state of a main transceiver and/or a wake up receiver of a network node after a specified time point or within a specified time period.
