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: The present application provide a resource allocation method, an access point, and a station. The method includes: determining a resource allocation sequence of N stations in a wireless local area network and a position of a resource allocated to each station in the N stations; determining resource allocation information according to the resource allocation sequence of the N stations and the position of the resource allocated to each station in the N stations, where the resource allocation information is used to reflect a relative position of the resource allocated to each station in the N stations; and sending resource indication information, so that each station in the N stations obtains, according to the resource indication information, the position of the resource allocated to each station. The method utilizes redundancy between indication information of different stations, so signaling overheads of resource indication information can be reduced.

Abstract: A method includes determining at least one first station; and sending first indication information to the first station, where the first indication information is used for indicating at least one first backoff duration, so that the first station performs a data transmission operation by using the first backoff duration, and the first backoff duration used by the first station to perform a data transmission operation is less than a second backoff duration used by a second station to perform a data transmission operation, or the first backoff duration used by the first station to perform a data transmission operation is greater than the second backoff duration used by the second station to perform a data transmission operation. Shortening backoff durations of some stations can ensure that these stations send data first, and extending backoff durations of some stations can ensure that the other stations send data first.
