For example, some techniques and apparatuses described herein provide multiplexing of the multiple forms of UCI as if they are associated with the same priority. In this way, latency is reduced relative to dropping a lower- priority form of UCI for the PUCCH, which may facilitate communication for low latency services such as ultra-reliable low latency communication (URFFC). Furthermore, some techniques and apparatuses described herein provide power control for the transmission of multiple forms of UCI on a single PUCCH.

Abstract

Les techniques décrites dans la présente invention concernent le multiplexage de multiples formes d'informations de commande de liaison montante (UCI) associées à différentes priorités sur un canal de commande de liaison montante physique (PUCCH) unique. Par exemple, certaines techniques et certains appareils décrits dans la présente invention concernent le multiplexage des multiples formes d'UCI comme si elles étaient associées à la même priorité. En outre, certaines techniques et certains appareils décrits dans la présente invention concernent une commande de puissance pour la transmission de multiples formes d'UCI sur un PUCCH unique. Par exemple, un UE peut appliquer une amplification de puissance dépendant de la taille de charge utile pour la commande de puissance d'un PUCCH sur la base, au moins en partie, du PUCCH portant de multiples formes d'UCI. En outre, certaines techniques et certains appareils décrits dans la présente invention concernent une technique de repli dans laquelle l'UE est associé à une marge de puissance insuffisante pour appliquer l'amplification de puissance dépendant de la taille de charge utile.
