Title
(EN) CHANNEL ACCESS PRIORITY FOR NR-U DATA BEARERS
(FR) PRIORITÉ D'ACCÈS AU CANAL POUR SUPPORTS DE DONNÉES NR-U
Abstract
(EN)
Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on the response link, such as uplink (UL), that includes multiple quality of service (QoS) flows for an UL transmission (such as for a configured grant UL transmission). The UE may receive a plurality of QoS flows in a common DRB from a base station. The UE may apply a rule to select a CAPC to apply for all QoS flows in the common DRB on an UL transmission. This rule may alternatively include the base station making the selection of the CAPC to apply and informing the UE of the selected CAPC for implementation. The UE may then apply the selected CAPC to the UL transmission.

La présente invention concerne des dispositifs, systèmes et procédés de communication sans fil liés à des mécanismes visant à aider un équipement utilisateur à déterminer la priorité d'accès au canal (CAPC) à utiliser pour un support radio de données (DRB) sur la liaison de réponse, telle que la liaison montante (UL), qui comprend de multiples flux de qualité de service (QoS) pour une transmission UL (telle qu'une transmission UL d'autorisation configurée). L'UE peut recevoir une pluralité de flux de QoS dans un DRB commun à partir d'une station de base. L'UE peut appliquer une règle pour sélectionner un CAPC à appliquer pour tous les flux de QoS dans le DRB commun sur une transmission UL. Cette règle peut également inclure la station de base qui sélectionne le CAPC à appliquer et informe l'UE du CAPC sélectionné pour la mise en œuvre. L'UE peut ensuite appliquer le CAPC sélectionné à la transmission UL.
