Abstract: front page image
(EN)The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and safety related service, or the like) on the basis of a 5G communication technology and an IoT related technology. The present invention provides a method for performing random access by a terminal in a wireless communication system supporting beamforming, the method comprising the steps of: receiving, from a base station, uplink resource information for transmitting a preamble and random access response (RAR) information corresponding to the resource information; determining, on the basis of the uplink resource information, a resource for transmitting at least one preamble through beam sweeping; and transmitting the at least one preamble to the base station through the beam sweeping.
(FR)La présente invention concerne une technique de communication pour la convergence d'une technologie de l’Internet des objets (IdO) avec un système de communication de cinquième génération (5G) pour la prise en charge d'un débit de transmission de données supérieur dépassant celui d’un système de quatrième génération (4G), et un système correspondant. La présente invention peut s’appliquer à un service intelligent (par exemple, une maison intelligente, un bâtiment intelligent, une ville intelligente, une voiture intelligente ou une voiture connectée, les soins de santé, l'enseignement numérique, le commerce de détail, les services liés à la sécurité et la sûreté, ou analogues) sur la base d’une technologie de communication 5G et d’une technologie d’IdO. La présente invention concerne un procédé pour effectuer un accès aléatoire par un terminal dans un système de communication sans fil prenant en charge la formation de faisceau, le procédé comprenant les étapes suivantes: la réception, en provenance d'une station de base, d'information de ressources de liaison montante pour la transmission d'un préambule et d'une information de réponse d'accès aléatoire (RAR) correspondant à l'information de ressource; la détermination, sur la base d'information de ressource de liaison montante, d'une ressource pour la transmission d'au moins un préambule par balayage de faisceau; et la transmission dudit au moins un préambule à la station de base par le balayage de faisceau.
(KO)본 개시는 4G 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G 통신 시스템을 IoT 기술과 융합하는 통신 기법 및 그 시스템에 관한 것이다. 본 개시는 5G 통신 기술 및 IoT 관련 기술을 기반으로 지능형 서비스 (예를 들어, 스마트 홈, 스마트 빌딩, 스마트 시티, 스마트 카 혹은 커넥티드 카, 헬스 케어, 디지털 교육, 소매업, 보안 및 안전 관련 서비스 등)에 적용될 수 있다. 본 발명은 빔포밍을 지원하는 무선 통신 시스템에서 기지국으로부터, 프리앰블을 전송하기 위한 상향링크 자원 정보 및 상기 자원 정보에 대응하는 RAR(Random Access Response) 정보를 수신하는 단계, 상기 상향링크 자원 정보에 기반하여 빔스위핑(beam sweeping)을 통해 적어도 하나의 프리앰블을 전송하기 위한 자원을 결정하는 단계 및 상기 기지국으로, 상기 빔스위핑을 통해 상기 적어도 하나의 프리앰블을 전송하는 단계를 포함하는 단말의 랜덤 엑세스 수행 방법을 제공한다.
