Abstract
(EN)
The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as Long-Term Evolution (LTE). The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety related services, and the like, on the basis of 5G communication technologies and IoT-related technologies. In addition, an operation method of a terminal in a wireless communication system may comprise the steps of: determining service information required by a V2X application and determining a V2X transmission mode; determining QoS information of a service required by the V2X application; obtaining sidelink radio bearer configuration information corresponding to the QoS information; and, using the obtained sidelink radio bearer configuration information, transmitting and receiving V2X packets by means of a device-to-device communication method.

La présente invention concerne un système de communication de 5e génération (5G) ou pré-5G destiné à prendre en charge un débit de transmission de données plus élevé que celui d’un système de communication de 4e génération (4G), tel qu’un système d’évolution à long terme (LTE). La présente invention peut être appliquée à des services intelligents, tels que des services associés à des maisons intelligentes, des bâtiments intelligents, des villes intelligentes, des voitures intelligentes ou des voitures connectées, des services associés à des soins de santé, à l’éducation numérique, à la vente au détail, à la sûreté et à la sécurité, et analogues, sur la base de technologies de communication 5G et de technologies associées à l’IdO. De plus, un procédé de fonctionnement d’un terminal dans un système de communication sans fil peut comprendre les étapes consistant à : déterminer des informations de service requises par une application V2X et déterminer un mode de transmission V2X ; déterminer des informations de QoS d’un service requis par l’application V2X ; obtenir des informations de configuration de porteur radio de liaison latérale correspondant aux informations de QoS ; et, utiliser les informations de configuration de porteur radio de liaison latérale obtenues, pour émettre et recevoir des paquets V2X au moyen d’un procédé de communication de dispositif à dispositif.
