Abstract
(EN)
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a random access method, including: acquiring configuration information, transmitting a first message including a preamble and an uplink shared channel according to the configuration information, and receiving a second message including contention resolution information from a base station.

La présente invention concerne un procédé et un système de communication permettant de combiner un système de communication de 5ème génération (5G) avec une technologie de l'Internet des objets (IdO) pour prendre en charge des débits de données supérieurs à ceux d'un système de 4ème génération (4G). La présente invention peut être appliquée à des services intelligents basés sur la technologie de communication 5G et sur la technologie de type IdO, tels que des services de maison intelligente, de bâtiment intelligent, de ville intelligente, de voiture intelligente, de voiture connectée, de soins de santé, d'enseignement numérique, de vente au détail intelligente, de sûreté et de sécurité. La présente invention concerne un procédé d'accès aléatoire, comprenant : l'acquisition d'informations de configuration, la transmission d'un premier message comprenant un préambule et un canal partagé de liaison montante selon les informations de configuration et la réception d'un second message comprenant des informations de résolution de conflits en provenance d'une station de base.
