摘要： A ML entity performs a backoff procedure of the primary link based on the backoff counter of the primary link; and when a count value of the backoff counter is 0, the ML entity sends a first PPDU on each first link in K first links, where the K first links include the primary link and K−1 first nonprimary links, and the first nonprimary link is in an idle state in a first inter-frame space before a time point at which the count value of the backoff counter decreases to 0.

摘要： When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.

摘要： 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.

摘要： A multi-band indication method includes generating, by a first communications device, a first frame, and sending, by the first communications device, the first frame. The first frame includes a first operating class field, and in response to a basic service set (BSS) configured to be established by the first communications device configured to simultaneously operate in a first band and a second band, the first operating class field indicates a starting frequency of the second band. The first band is a band that includes a primary channel and the second band is a band that fails to include the primary channel.

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： A multi-link communication method is implemented by an access point (AP) multi-link device (MLD). The multi-link communication method includes generating a first frame, and sending the first frame on a first link. The first frame includes a supported rates and a basic service set (BSS) membership selectors element, the element includes first indication information, and the first indication information indicates that a non-AP MLD is disallowed to initiate multi-link setup with the AP MLD on the first link.

摘要： A data scheduling method and apparatus. The method includes: allocating, by an access point (AP), at least one of a plurality of primary channels to each of a plurality of stations (STAs), where active access is forbidden on the plurality of primary channels; and synchronously scheduling, by the AP, a STA on a channel including at least one idle primary channel, where the synchronously scheduled STA is a STA allocated to the at least one idle primary channel, and the at least one idle primary channel is at least one of the plurality of primary channels. The AP sets the plurality of primary channels, so that the AP can flexibly schedule the station by using the idle primary channel. This avoids a problem caused by setting only one primary channel, thereby improving data transmission efficiency.

摘要： Embodiments of this application provide a probe request and response technology between a station and a plurality of AP MLDs. If the station wants to obtain a communication parameter of a nontransmitted BSSID AP, the station may send a probe request frame to a nontransmitted BSSID AP in an MBSSID set, and a transmitted BSSID AP in the MBSSID set may reply with a probe response frame. Alternatively, if the station wants to probe a plurality of AP MLDs at a time, the station may send the probe request frame to one transmitted BSSID AP in the MBSSID set, to request the AP to reply with a communication parameter of the nontransmitted BSSID AP. The nontransmitted BSSID AP and the transmitted BSSID AP may belong to different AP MLDs. During implementation of this application, a station may obtain communication parameters of a plurality of APs of one or more AP MLDs by sending one probe request frame, to obtain communication parameters of the AP MLD on a plurality of links, thereby efficiently implementing association between the station and the AP MLD or establishing multi-link transmission between the station and the AP MLD.

摘要： A method includes an access point device that obtains a transmission opportunity (TXOP) in a wireless local area network (WLAN) and that allocates a first period in the TXOP to a non-access point device for data transmission. The access point device receives a first frame in the first period. An access address or a transmitter address of the first frame is associated with the non-access point device. The method further includes that the access point device keeps, based on the first frame, a network allocation vector (NAV) unchanged.
