Abstract
(EN)
Provided in the present specification is a method for transmitting and receiving data between a terminal and a base station in a narrow band wireless communication system. Particularly, a preconfigured uplink resource (PUR) configuration is transmitted to a terminal through RRC signaling, a PUR receives uplink data from the terminal when the terminal is in an idle mode, and feedback about the uplink data is transmitted to the terminal, wherein the feedback is transmitted through an NPDCCH after a specific time after the PUR reception.

La présente invention concerne un procédé de transmission et de réception de données entre un terminal et une station de base dans un système de communication sans fil à bande étroite. En particulier, une configuration de ressource de liaison montante configurée au préalable (PUR) est transmise à un terminal par l'intermédiaire d'une signalisation RRC, une PUR reçoit des données de liaison montante du terminal lorsque le terminal est dans un mode inactif, et une rétroaction concernant les données de liaison montante est transmise au terminal, la rétroaction étant transmise par l'intermédiaire d'un NPDCCH après un temps spécifique après la réception de PUR.
(KO)
본 명세서는 협대역 무선 통신 시스템에서 단말과 기지국 사이의 데이터 송수신 방법을 제공한다. 구체적으로, RRC 시그널링을 통해 기설정된 상향링크 자원 설정을 단말로 전송하고, 단말이 유휴 모드(Idle mode)인 경우, 단말로부터 PUR에서 상향링크 데이터를 수신하며, 상향링크 데이터에 대한 피드백을 단말로 전송하되, 피드백은 PUR 수신 이후 특정 시간 이후에 NPDCCH를 통해 전송하는 것으로 설정된다.
