摘要： Embodiments of this application disclose a communication method and a communication apparatus applied to a wireless communication system, to provide a signaling design solution applicable to a scenario of multi-AP coordinated transmission. An embodiment of this application provides a communication method, including: a first access point (AP) generates notification information, where the notification information indicates a station (STA) that is to send a channel sounding physical layer protocol data unit (PPDU), the notification information includes identification information of the STA and identification information of a second AP, the identification information of the STA indicates the STA, and the identification information of the second AP indicates the second AP. The first AP sends the notification information to the second AP and to the STA.

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.
