Title (EN) SIGNAL TRANSMISSION AND RECEPTION METHOD ON BASIS OF LTE AND NR IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
(FR) PROCÉDÉ D'ÉMISSION ET DE RÉCEPTION DE SIGNAL BASÉ SUR LTE ET NR DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET DISPOSITIF ASSOCIÉ

Abstract:
(EN) The present invention relates to signal transmission and reception method and device by a new radio (NR) access technology equipment in a wireless communication system. The present invention comprises the steps of: confirming a physical downlink control channel (PDCCH) order; and, if the PDCCH order is confirmed, initiating a random access procedure. The random access procedure is characterized by being configured such that, if a first uplink carrier and a second uplink carrier are configured, a random access preamble is transmitted by means of a particular uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.
(FR) La présente invention concerne un procédé et un dispositif d'émission et de réception de signal par un équipement de technologie d'accès New Radio (NR) dans un système de communication sans fil. La présente invention comprend les étapes consistant à : confirmer un ordre de canal de commande de liaison descendante physique (PDCCH); et, si l'ordre de PDCCH est confirmé, déclencher une procédure d'accès aléatoire. La procédure d'accès aléatoire est caractérisée en ce qu'elle est configurée de telle sorte que, si une première porteuse de liaison montante et une seconde porteuse de liaison montante sont configurées, un préambule d'accès aléatoire est transmis au moyen d'une porteuse de liaison montante particulière correspondant à un indicateur associé à l'ordre de PDCCH parmi la première porteuse de liaison montante et la seconde porteuse de liaison montante.
(KO) 본 발명은 무선 통신 시스템에서 NR (New Radio Access Technology) 단말의 신호 송수신 방법 및 장치에 관한 것이다. PDCCH 오더(Physical Downlink Control CHannel order)를 확인하는 단계 및 PDCCH 오더가 확인되면, 랜덤 액세스 절차(random access procedure)를 시작(initiate)하는 단계를 포함하며, 랜덤 액세스 절차는, 제 1 상향링크 캐리어 및 제 2 상향링크 캐리어가 설정된 경우, 제 1 상향링크 캐리어 및 제 2 상향링크 캐리어 중 PDCCH 오더와 연관된 지시자에 대응되는 특정 상향링크 캐리어를 통하여 랜덤 액세스 프리엠블(Random Access Preamble)을 전송하도록 설정되는 것을 특징으로 한다.
