Title
(EN) OVERLAPPING MULTI-SLOT AND SINGLE-SLOT CONTROL CHANNEL RESOURCES
(FR) RESSOURCES DE CANAL DE COMMANDE À CRÉNEAUX MULTIPLES ET À CRÉNEAU UNIQUE EN CHEVAUCHEMENT
Abstract
(EN)
A wireless device (12) determines that an uplink control channel resource (20B) for a multi-slot uplink control channel transmission (16B) overlaps in time with an uplink control channel resource (20A) for a single-slot uplink control channel transmission (16A) in a slot (18X). The wireless device (12) decides, for the slot (18X), either to drop whichever of the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A) carries uplink control information of a lower priority or to drop a certain one of the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A), depending on whether the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A) carry uplink control information of different priorities or the same priority, respectively. The wireless device (12) drops the single-slot uplink control channel transmission (16A) or the multi-slot uplink control channel transmission (16B) in the slot (18X), according to that decision.
(FR)
Selon l'invention, un dispositif (12) sans fil détermine qu'une ressource (20B) de canal de commande de liaison montante pour une transmission (16B) de canal de commande de liaison montante à créneaux multiples est en chevauchement temporel avec une ressource (20A) de canal de commande de liaison montante pour une transmission (16A) de canal de commande de liaison montante à créneau unique dans un créneau (18X). Le dispositif (12) sans fil décide, pour le créneau (18X), soit d'abandonner une transmission quelconque, parmi la transmission (16B) de canal de commande de liaison montante à créneaux multiples et la transmission (16A) de canal de commande de liaison montante à créneau unique, qui transporte des informations de commande de liaison montante d'une priorité plus basse, soit d'abandonner une certaine transmission parmi la transmission (16B) de canal de commande de liaison montante à créneaux multiples et la transmission (16A) de canal de commande de liaison montante à créneau unique, suivant que la transmission (16B) de canal de commande de liaison montante à créneaux multiples et la transmission (16A) de canal de commande de liaison montante à créneau unique transportent des informations de commande de liaison montante de priorités différentes ou de la même priorité, respectivement. Le dispositif (12) sans fil abandonne la transmission (16A) de canal de commande de liaison montante à créneau unique ou la transmission (16B) de canal de commande de liaison montante à créneaux multiples dans le créneau (18X), selon cette décision.
