Title
(EN) USER EQUIPMENT AND BASE STATION INVOLVED IN TRANSMISSION OF UPLINK CONTROL DATA
(FR) ÉQUIPEMENT UTILISATEUR ET STATION DE BASE IMPLIQUÉS DANS LA TRANSMISSION DE DONNÉES DE COMMANDE DE LIAISON MONTANTE
Abstract
(EN)
The present disclosure relates to a user equipment (UE) which receives, from a base station via an unlicensed radio cell, uplink configuration information to configure at least one set of radio resources of the unlicensed radio cell available for transmitting uplink control information, the radio resource set being associated with a UE group ID indicating a UE group to which the UE is associated. The UE receives, from the base station, downlink control information, DCI, indicating a UE group ID. The UE, when determining that the associated UE group ID is the same as the UE group ID indicated by the DCI, determines scheduling request radio resources within the at least one set of uplink control information radio resources based on the received downlink control information. The UE transmits a scheduling request to the base station using the determined scheduling request radio resources.
(FR)
La présente invention concerne un équipement utilisateur (UE) qui reçoit, en provenance d'une station de base par l'intermédiaire d'une cellule radio sans licence, des informations de configuration de liaison montante servant à configurer au moins un ensemble de ressources radio de la cellule radio sans licence disponibles pour transmettre des informations de commande de liaison montante, l'ensemble de ressources radio étant associé à un identifiant (ID) de groupe d'UE indiquant un groupe d'UE auquel l'UE est associé. L'UE reçoit, en provenance de la station de base, des informations de commande de liaison descendante, DCI, indiquant un ID de groupe d'UE. L'UE, lorsqu'il détermine que l'ID de groupe d'UE associé est identique à l'ID de groupe d'UE indiqué par les DCI, détermine des ressources radio pour requête de planification au sein de l'au moins un ensemble de ressources radio pour informations de commande de liaison montante sur la base des informations de commande de liaison descendante reçues. L'UE transmet une requête de planification (SR) à la station de base à l'aide des ressources radio pour requête de planification déterminées.
