US 12,003,399 B2 · Request and response method for probing MLD, station, and access point

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.

Dependent claims

A station in a wireless local area network (WLAN), comprising:

at least one processor;
and
a memory storing a program that is executable by the at least one processor, the program including instructions to:
generate a probe request frame, wherein the probe request frame requests an first access point (AP) to feed back a communication parameter that is of an AP multi-link device (MLD) and that is related to the first AP, wherein the communication parameter requested by the probe request frame comprises:
the communication parameter of the AP MLD in which another AP belonging to a same multiple transmitted basic service set identifier (MBSSID) set as the first AP is located, the first AP is a transmitted basic service set identifier (BSSID) AP, and the communication parameter of the AP MLD comprises communication parameters of a plurality of links supported by the AP MLD, and wherein the probe request frame carries first lists of identifiers of first information elements, each first list of identifiers of first information elements corresponding to an AP in the AP MLD, to request content of the first information elements of the corresponding AP in the AP MLD;
and
a transceiver, configured to send the probe request frame to the first AP.

A method comprising:

generating, by a station in a wireless local area network (WLAN), a probe request frame, wherein the probe request frame requests a first access point (AP) to feed back a communication parameter that is of an AP multi-link device (MLD) and that is related to the first AP, wherein the communication parameter requested by the probe request frame comprises:
the communication parameter of the AP MLD in which another AP belonging to a same multiple transmitted basic service set identifier (MBSSID) set as the first AP is located, the first AP being is a transmitted basic service set identifier (BSSID) AP, and the communication parameter of the AP MLD comprises communication parameters of a plurality of links supported by the AP MLD, and wherein the probe request frame carries first lists of identifiers of first information elements, each first list of identifiers of first information elements corresponding to an AP in the AP MLD, to request content of the first information elements of the corresponding AP in the AP MLD;
and
sending, by the station, the probe request frame to the first AP.
