Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a number of bits to be used in an indication of at least one of a listen-before-talk (LBT) category or a channel access priority class to be used for uplink communications. The UE may receive the indication of at least one of the LBT category or the channel access priority class to be used for a transmission starting point associated with one or more uplink communications, wherein the indication includes the number of bits indicated in the configuration. The UE may perform an LBT procedure for an uplink communication, of the one or more uplink communications, transmitted at the transmission starting point, according to the LBT category or the channel access priority class. Numerous other aspects are provided.

Divers aspects de la présente divulgation concernent de manière générale la communication sans fil. Dans certains aspects, un équipement utilisateur (UE) peut recevoir une configuration qui indique un nombre de bits à utiliser dans une indication d'au moins l'une d'une catégorie d'écoute avant de parler (LBT) ou d'une classe de priorité d'accès à un canal à utiliser pour des communications de liaison montante. L'UE peut recevoir l'indication d'au moins l'une de la catégorie LBT ou de la classe de priorité d'accès à un canal à utiliser pour un point de départ de transmission associé à une ou plusieurs communications de liaison montante, l'indication comprenant le nombre de bits indiqué dans la configuration. L'UE peut effectuer une procédure LBT pour une communication de liaison montante, de la ou des communications de liaison montante, transmises au niveau du point de départ de transmission, selon la catégorie LBT ou la classe de priorité d'accès à un canal. De nombreux autres aspects sont fournis.
