(EN) METHOD AND APPARATUS FOR AUTOMATIC GAIN CONTROL IN VEHICLE-TO-EVERYTHING SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR LA COMMANDE AUTOMATIQUE DE GAIN DANS UN SYSTÈME VÉHICULE-À-TOUT
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 A method by a first terminal in a wireless communication system is provided. The method includes determining whether to transmit a preamble for an automatic gain control (AGC), determining a slot and at least one symbol in the slot to transmit the preamble for the AGC, in a case in which it is determined to transmit the preamble for the AGC, and transmitting, to a second terminal, the preamble for the AGC in the determined slot and the at least one symbol in the slot.

La présente invention se rapporte à un procédé et à un système de communication permettant de fusionner un système de communication de 5è génération (5G) avec une technologie associée à l’Internet des objets (IdO), pour qu'il prenne en charge des débits de données supérieurs à ceux d’un système de 4è 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'éducation numérique, de vente au détail intelligente, de sûreté et de sécurité. Le procédé consiste à déterminer s'il faut transmettre un préambule pour une commande de gain automatique (AGC), à déterminer un créneau et au moins un symbole dans le créneau pour transmettre le préambule pour l'AGC, dans le cas où il est déterminé de transmettre le préambule pour l'AGC, et transmettre, à un second terminal, le préambule pour l'AGC dans le créneau déterminée et le ou les symboles dans le créneau.
