摘要： In a method for determining a candidate line of sight path, a wireless local area network device receives a signal, where the signal includes radio signals sent by a to-be-identified terminal through a plurality of paths. The radio signal includes a first training sequence, and the signal includes superposition of a plurality of first training sequences transmitted through the plurality of paths. The wireless local area network device matches the signal and a second training sequence to obtain time points at which the plurality of first training sequences transmitted through the plurality of paths are received. The wireless local area network device determines a path of an earliest-received radio signal as a candidate line of sight path.

摘要： 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.
