Abstract: front page image
(EN)The present specification discloses a method for transmitting a demodulation reference signal (DMRS) for uplink data demodulation by a machine type communication (MTC) device which is configured to operate in only a part of the system band of a cell. The method may comprise the steps of: mapping a DMRS sequence to 12 sub-carriers of a physical resource block (PRB); and dividing the PRB, to which the DMRS is mapped, into N sub-PRBs. Here, each of the sub-PRBs may comprise 12/N sub-carriers to which the DMRS is mapped. The method may further comprise a step for transmitting the N sub-PRBs to a base station in N sub-frames.
(FR)La présente invention concerne un procédé d'émission d'un signal de référence de démodulation (DMRS) de démodulation de données de liaison montante par un dispositif de communication de type machine (MTC) qui est configuré pour ne fonctionner que dans une partie de la bande de système d'une cellule. Le procédé peut comprendre les étapes consistant à : mettre en correspondance une séquence de DMRS avec 12 sous-porteuses d'un bloc de ressource physique (PRB) ; et diviser le PRB, avec lequel le DMRS est mis en correspondance, en N sous-PRB. Ici, chacun des sous-PRB peut comprendre 12/N sous-porteuses avec lesquelles le DMRS est mis en correspondance. Le procédé peut en outre comprendre une étape consistant à transmettre les N sous-PRB à une station de base dans N sous-trames.
(KO)본 명세서의 개시는 셀의 시스템 대역 중 일부 대역에서만 동작하도록 설정된 MTC(Machine Type communication) 기기가 상향링크 데이터의 복조를 위한 DMRS(demodulation reference signal)를 전송하는 방법을 제공한다. 상기 방법은 DMRS 시퀀스를 PRB(Physical Resource Block)의 12개 부반송파에 매핑하는 단계와; 상기 DMRS가 매핑된 PRB를 N개의 부-PRB로 나누는 단계를 포함할 수 잇다. 여기서 각 부-PRB는 상기 DMRS가 매핑된 12/N개의 부반송파를 포함할 수 있다. 상기 방법은 상기 N개의 부-PRB들을 N개의 서브프레임 상에서 기지국으로 전송하는 단계를 또한 포함할 수 있다.
