Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).

Abstract: An association establishment method and apparatus for carrying out the method are described. The association establishment 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. The method further comprises receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts 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.

Abstract: The present invention discloses a data transmission method, apparatus, and system, and an access point. An example method includes: transceiving data of a data portion in an uplink OFDMA PPDU scheduled by an access point AP on a corresponding allocated frequency resource unit RU, determining one or more fundamental channel units on which the allocated frequency resource unit RU is located, and transceiving at least some fields in a common signaling portion in the uplink OFDMA PPDU on the determined one or more fundamental channels. In some implementations, one or more fundamental channels for transceiving at least some fields in a common signaling portion in an uplink OFDMA PPDU are determinate, and another user can transceive data on another idle fundamental channel, thereby improving channel utilization. In addition, multiple users can simultaneously transceive data on multiple fundamental channels, thereby improving a service transmission rate.
