Abstract: This application describes resource unit indication methods, access points, and stations. In an example method, a resource unit allocation subfield in a trigger frame includes a frequency band range indication and a resource unit indication. The resource unit indication is used to indicate a multi-resource unit (MRU) allocated to a station. The frequency band range indication is used to indicate a frequency band range in which a resource unit (RU) in the MRU is located. For example, the frequency band range indication is used to indicate 80 MHz in which a smallest RU in the MRU is located.

Abstract: 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.

Abstract: 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.

Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.

Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.
