Abstract

Des modes de réalisation de la présente divulgation se rapportent au domaine technique des communications mobiles. Sont proposés un procédé de communication, un dispositif électronique, et un support de stockage. Le procédé de communication est appliqué à un point d'accès (AP). Le procédé consiste à : envoyer une première trame radio à un dispositif station et, au moyen de premières informations d'indication de la première trame radio et/ou du temps de transmission de la première trame radio, indiquer si la première trame radio comprend un identifiant d'utilisateur (UID) attribué par l'AP au dispositif station, dans lequel le dispositif station est un dispositif station non associé (U-STA) qui n'est pas associé initialement à l'AP. Les modes de réalisation de la présente divulgation proposent un procédé permettant de déterminer si un AP doit, ou non, attribuer un UID à une U-STA
