Title (EN) PHYSICAL RANDOM ACCESS CHANNEL DESIGN FOR LICENSED ASSISTED ACCESS
(FR) CONCEPTION DE CANAL D'ACCÈS ALÉATOIRE PHYSIQUE POUR ACCÈS SOUS LICENCE
Abstract:
(EN) An apparatus is configured to be employed within one or more user equipment (UE). The apparatus includes control circuitry and a transceiver. The control circuitry is configured to generate a physical random access channel (PRACH), wherein the PRACH includes a preamble for PRACH transmission using a license assisted access (LAA) secondary cell. The transceiver is coupled to the control circuitry and is configured to retry transmission of the PRACH on a listen before talk (LBT) failure based of the secondary cell.
(FR) La présente invention concerne un appareil qui est configuré pour être utilisé dans un ou plusieurs équipements utilisateur (UE). Cet appareil comprend un circuit de commande et un émetteur-récepteur. Le circuit de commande est configuré pour générer un canal d'accès aléatoire physique (PRACH), le PRACH comprenant un préambule destiné à une transmission de PRACH à l'aide d'une cellule secondaire d'accès sous licence (LAA). L'émetteur-récepteur est couplé au circuit de commande et configuré pour réessayer la transmission de PRACH en cas de défaillance d'accès multiple avec écoute de porteuse (LBT) sur la base de la cellule secondaire.
