Abstract: Embodiments of the present invention provide an association establishment method and apparatus. The method includes: broadcasting, by an access point AP, a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs; receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs; broadcasting, by the AP, a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message. In this way, the AP is associated with the unassociated stations STA, and communication reliability is ensured.

Abstract: Embodiments of the present application disclose a station association method and apparatus. The station association method includes: receiving a message sent by at least one access point AP, where the message carries a wake-up radio load information element, and the wake-up radio load information element includes load information of a wake-up radio channel managed by the AP; and selecting, based on the load information, a target AP from the at least one AP, so as to perform association. In the embodiments of the present application, a STA can be notified of load information of a wake-up radio channel managed by an AP, so that the STA selects an appropriate AP to perform association.

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.
