  • Patent number: 10159031
    Abstract: The present invention discloses an access point, a station, and a beacon frame sending method and system, relates to the communications field, and resolves a problem of relatively large network overheads caused for purposes of ensuring that in a WLAN system having multiple channels, a STA can quickly access a network. A specific solution is as follows: A first sending unit sends a beacon indication frame on each subchannel of N subchannels, where the beacon indication frame is used to indicate configuration information of a beacon frame; and a second sending unit sends the beacon frame on at least one first subchannel. The present invention is applied to a beacon frame sending process.
