Abstract: front page image
(EN)The embodiments of the present invention relate to a wireless access system supporting an unlicensed band and to methods for generating a discovery signal (DRS), methods for generating and transmitting a channel state information reference signal included in the DRS, and devices for supporting same. The method for transmitting a discovery signal (DRS) including a channel state information reference signal (CSI-RS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present invention, may comprise the steps of: initiating, in subframe n (SF #n), a listen-before-talk (LBT) procedure for checking whether the unlicensed band is idle or not; if an LBT procedure succeeds in SF #n+k, generating a sequence for transmitting the CSI-RS on the basis of the subframe index j indicating SF #j; and transmitting the DRS, including the CSI-RS, in SF #n+k. Here, n, k, and j are preferably integers greater than or equal to 0 and less than or equal to 9.
(FR)Conformément à des modes de réalisation, la présente invention concerne un système d’accès sans fil prenant en charge une bande non autorisée et des procédés pour générer un signal de découverte (DRS), des procédés pour générer et émettre un signal de référence d’informations d’état de canal inclus dans le DRS, et des dispositifs pour les prendre en charge. Le procédé pour émettre un signal de découverte (DRS) comprenant un signal de référence d’informations d’état de canal (CSI-RS) dans un système d’accès sans fil prenant en charge une bande non autorisée, selon un mode de réalisation de la présente invention, peut consister : à lancer, dans une sous-trame n (SF #n), un processus d’accès multiple avec écoute de porteuse (LBT) pour vérifier si la bande non autorisée est au repos ou non ; si un processus LBT valide SF #n + k, à générer une séquence pour émettre le CSI-RS sur la base de l’indice de sous-trame j indiquant SF #j ; à émettre le DRS, comprenant le CSI-RS, dans SF #n + k. Dans la présente invention, n, k et j sont, de préférence, des nombres entiers supérieurs ou égaux à 0 et inférieurs ou égaux à 9.
(KO)본 발명의 실시예들은 비면허 대역을 지원하는 무선 접속 시스템에 관한 것으로, 디스커버리 신호(DRS)을 생성하는 방법들, DRS에 포함된 채널 상태 정보 참조 신호를 생성 및 전송하는 방법들 및 이를 지원하는 장치들에 관한 것이다. 본 발명의 일 실시예로서 비면허대역을 지원하는 무선접속시스템에서 채널상태정보 참조 신호(CSI-RS)를 포함하는 디스커버리 신호(DRS)를 전송하는 방법은, 서브프레임 n(SF #n)에서 비면허대역이 유휴 상태인지 여부를 확인하기 위한 LBT(Listen Before Talk) 과정을 시작하는 단계와 SF #n+k에서 LBT 과정이 성공하면, SF #j를 나타내는 서브프레임 인덱스 j를 기반으로 CSI-RS를 전송하기 위한 시퀀스를 생성하는 단계와 CSI-RS를 포함하는 DRS를 SF #n+k에서 전송하는 단계를 포함할 수 있다. 이때, n, k 및 j는 0 보다 크거나 같고 9보다 작거나 같은 정수인 것이 바람직하다.
