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.
