Abstract
(EN)
The present invention relates to a method for transmitting an uplink reference signal in a multi-node system and a terminal using same. The method comprises the steps of: receiving a synchronization signal from a node; receiving parameters for a virtual cell identifier(ID) from the node; generating an uplink demodulation reference signal(DM-RS) using the parameters for the virtual cell ID; and transmitting the generated uplink DM-RS to the node, wherein a physical cell ID is a cell ID obtained from the synchronization signal, and the parameters for the virtual cell ID are parameters used for generating the uplink DM-RS in the replacement of the physical cell ID.
(FR)
L'invention concerne un procédé de transmission d'un signal de référence de liaison montante dans un système à nœuds multiples, et un terminal utilisant ce procédé. Le procédé consiste à: recevoir d'un noeud un signal de synchronisation; recevoir du noeud des paramètres pour un identifiant de cellule virtuelle (ID); générer un signal de référence de démodulation de liaison montante (DM-RS) en utilisant les paramètres pour l'identifiant de cellule virtuelle (ID); et transmettre le DM-RS de liaison montante généré au nœud. Un ID de cellule physique est un ID de cellule obtenu du signal de synchronisation, et les paramètres pour l'ID de cellule virtuelle sont des paramètres utilisés pour générer le DM-RS de liaison montante en remplacement de l'ID de cellule physique.

다중 노드 시스템에서 단말의 상향링크 기준 신호 전송 방법 및 상기 방법을 이용하는 단말을 제공한다. 상기 방법은 노드로부터 동기화 신호를 수신하는 단계; 상기 노드로부터 가상 셀 ID(identifier)에 대한 파라미터를 수신하는 단계; 상기 가상 셀 ID에 대한 파라미터를 이용하여 상향링크 복조 기준 신호(demodulation reference signal : DM-RS)를 생성하는 단계; 및 상기 생성된 상향링크 DM-RS를 상기 노드로 전송하는 단계를 포함하되, 물리적 셀 ID는 상기 동기화 신호로부터 수신되는 셀 ID 이고, 상기 가상 셀 ID에 대한 파라미터는 상기 물리적 셀 ID를 대체하여 상기 상향링크 DM-RS를 생성하는데 사용되는 파라미터인 것을 특징으로 한다.
