Abstract
(EN)
This disclosure provides systems, methods, and apparatuses for associating a wireless communication device such as a wireless station (STA) of a STA multi-link device (MLD) with an access point (AP) MLD that includes a first AP associated with a first communication link of the AP MLD and includes one or more secondary APs associated with one or more respective secondary communication links of the first AP MLD. The AP MLD transmits a frame including an advertising information element carrying discovery information for the first AP of the AP MLD, including a first portion carrying discovery information for each secondary AP of the one or more secondary APs of the AP MLD, and including a second portion carrying common attributes of the one or more secondary APs of the AP MLD.

L'invention concerne des systèmes, des procédés et des appareils pour associer un dispositif de communication sans fil tel qu'une station sans fil (STA) d'un dispositif à liaisons multiples STA (MLD) avec un point d'accès (AP) MLD qui comprend un premier AP associé à une première liaison de communication de l'AP MLD et comprend un ou plusieurs AP secondaires associés à une ou plusieurs liaisons de communication secondaires respectives du premier AP MLD. L'AP MLD transmet une trame comprenant un élément d'informations publicitaires comportant des informations de découverte pour le premier AP de l'AP MLD, comprenant une première partie comportant des informations de découverte pour chaque AP secondaire du ou des AP secondaires de l'AP MLD, et comprenant une seconde partie comportant des attributs communs du ou des AP secondaires de l'AP MLD.
