Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A central access node (CAN) may manage and schedule resources for a wireless mesh network. The CAN may transmit a first message to a relay access node (AN) to expedite transmission of a priority communication in the wireless mesh network. The first message may provide configuration information for modifying a preconfigured schedule to expedite the transmission of the priority communication. For example, the first message may provide configuration information to modify a preconfigured schedule to allow a first network node to transmit the priority communication to a second network node during a reserved time period. The relay AN may generate a second message regarding the modified schedule and transmit the second message to the second network node.

La présente invention concerne des procédés, des systèmes et des dispositifs de communications sans fil. Un nœud d'accès central (CAN) peut gérer et planifier des ressources pour un réseau maillé sans fil. Le nœud CAN peut transmettre un premier message à un nœud d'accès relais (AN) pour accélérer la transmission d'une communication prioritaire dans le réseau maillé sans fil. Le premier message peut fournir des informations de configuration pour modifier un calendrier préconfiguré pour accélérer la transmission de la communication prioritaire. Par exemple, le premier message peut fournir des informations de configuration pour modifier un calendrier préconfiguré pour permettre à un premier nœud de réseau de transmettre la communication prioritaire à un second nœud de réseau pendant une période de temps réservée. Le nœud AN relais peut générer un second message concernant le calendrier modifié et transmettre le second message au second nœud de réseau.
