Title
(EN) USER DEVICES FOR A WIRELESS COMMUNICATION SYSTEM AND METHODS FOR COMMUNICATING IN A WIRELESS COMMUNICATION SYSTEM
(FR) DISPOSITIFS UTILISATEUR POUR UN SYSTÈME DE COMMUNICATION SANS FIL ET PROCÉDÉS DE COMMUNICATION DANS UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract
(EN)
A user device for a wireless communication system including a plurality of user devices is to communicate with a further user device using a sidelink. The user device is to transmit a transmit a first stage sidelink control information describing reserved resources for transmission of further information comprising a second stage sidelink control information, wherein the first stage sidelink control information comprises an information indicating whether a traffic type is periodic or aperiodic. Further user devices and methods for communicating in a wireless communication system are described.

La présente invention concerne un dispositif utilisateur pour un système de communication sans fil comprenant une pluralité de dispositifs utilisateur qui sont destinés à communiquer avec un autre dispositif utilisateur à l'aide d'une liaison latérale. Le dispositif utilisateur doit transmettre des informations de commande de liaison latérale de premier étage décrivant des ressources réservées à la transmission d'autres informations comprenant des informations de commande de liaison latérale de second étage, les informations de commande de liaison latérale de premier étage comprenant des informations indiquant si un type de trafic est périodique ou apériodique. La présente invention concerne en outre des dispositifs utilisateur et des procédés de communication dans un système de communication sans fil.
