Abstract:
(EN) The present invention relates to a method for performing, by a terminal, a random access process in a wireless communication system supporting first and second preamble formats, and an apparatus therefor. Particularly, the present invention relates to a method comprising: a step of receiving narrowband physical random access channel (NPRACH) configuration information; and a step of transmitting a random access preamble on the basis of a preamble format indicated by the NPRACH configuration information of the first and second preamble formats, wherein the length of one symbol of the second preamble format corresponds to three times the length of one symbol of the first preamble format, and the first preamble format has a frequency grid spacing of 3.75 kHz, and the second preamble format has a frequency grid spacing of 1.25 kHz, and to an apparatus therefor.
(FR) La présente invention concerne un procédé de réalisation, par un terminal, d'un processus d'accès aléatoire dans un système de communication sans fil prenant en charge des premier et second formats de préambule, et un appareil associé. En particulier, la présente invention concerne un procédé comprenant : une étape de réception d'informations de configuration d'un canal d'accès aléatoire physique à bande étroite (NPRACH) ; et une étape de transmission d'un préambule d'accès aléatoire sur la base d'un format de préambule indiqué par les informations de configuration de NPRACH des premier et second formats de préambule, la longueur d'un symbole du second format de préambule correspondant à trois fois la longueur d'un symbole du premier format de préambule et le premier format de préambule ayant un espacement de grille de fréquence de 3,75 kHz et le second format de préambule ayant un espacement de grille de fréquence de 1,25 kHz et un appareil pour celui-ci.
(KO) 본 발명은 제1 프리앰블 포맷과 제2 프리앰블 포맷을 지원하는 무선 통신 시스템에서 단말이 랜덤 접속 과정을 수행하는 방법 및 이를 위한 장치에 관한 것으로서, 구체적으로 본 발명은 NPRACH(Narrowband Physical Random Access Channel) 구성 정보를 수신하는 단계; 및 상기 제1 프리앰블 포맷과 상기 제2 프리앰블 포맷 중에서 상기 NPRACH 구성 정보가 지시하는 프리앰블 포맷에 기반하여 랜덤 접속 프리앰블을 전송하는 단계를 포함하되, 상기 제2 프리앰블 포맷의 하나의 심볼 길이는 상기 제1 프리앰블 포맷의 하나의 심볼 길이의 3배에 해당하고, 상기 제1 프리앰블 포맷은 3.75 kHz의 주파수 그리드 간격을 가지고, 상기 제2 프리앰블 포맷은 1.25 kHz의 주파수 그리드 간격을 가지는 방법 및 이를 위한 장치에 관한 것이다.
