Abstract

Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut générer un message multiplexé comprenant des premières informations ayant une première priorité et des secondes informations ayant une seconde priorité, la première priorité étant supérieure à la seconde priorité. L'UE peut transmettre le message multiplexé à l'aide d'un décalage cyclique particulier d'un ensemble particulier de décalages cycliques parmi une pluralité d'ensembles de décalages cycliques, l'ensemble particulier de décalages cycliques étant basé au moins en partie sur les premières informations et le décalage cyclique particulier étant basé au moins en partie sur les secondes informations. De nombreux autres aspects sont décrits.
