Summary:A method for receiving a PDCCH by a terminal in a mobile communication system may comprise the steps of: receiving a first PDCCH including first DCI from a base station through a first PDCCH search space; and receiving a second PDCCH including second DCI from the base station through a second PDCCH search space, wherein the first DCI and second DCI are for scheduling the same PDSCH for the same TB or TBs associated with the same HARQ process, are for scheduling different PDSCHs for the same TB or TBs associated with the same HARQ process, or are for scheduling different PDSCHs for different TBs or TBs associated with different HARQ processes. In addition, the first DCI and second DCI may be received from the base station within a time window. L'invention concerne un procédé de réception d'un PDCCH par un terminal dans un système de communication mobile pouvant comprendre les étapes consistant à : recevoir un premier PDCCH comprenant des premières DCI provenant d'une station de base par l'intermédiaire d'un premier espace de recherche de PDCCH ; et recevoir un second PDCCH comprenant des secondes DCI provenant de la station de base par l'intermédiaire d'un second espace de recherche de PDCCH, les premières DCI et les secondes DCI étant destinées à planifier le même PDSCH pour le ou les mêmes TB associés au même processus HARQ, étant destinées à planifier différents PDSCH pour le ou les mêmes TB associés au même processus HARQ ou étant destinées à planifier différents PDSCH pour un ou plusieurs TB différents associés à différents processus HARQ. En outre, les premières DCI et les secondes DCI peuvent être reçues de la station de base dans une fenêtre temporelle. 이동 통신 시스템에서 단말에 의해 수행되는 PDCCH 수신 방법은 제1 PDCCH 탐색 공간을 통하여 제1 DCI를 포함한 제1 PDCCH를 기지국으로부터 수신하는 단계; 및 제2 PDCCH 탐색 공간을 통하여 제2 DCI를 포함한 제2 PDCCH를 상기 기지국으로부터 수신하는 단계를 포함하고, 상기 제1 DCI와 제2 DCI는 동일한 TB 또는 동일한 HARQ 프로세스에 속한 TB들에 대한 동일한 PDSCH를 스케줄링하기 위한 것이거나, 동일한 TB 또는 동일한 HARQ 프로세스에 속한 TB들에 대한 서로 다른 PDSCH를 스케줄링하기 위한 것이거나, 서로 다른 TB 또는 서로 다른 HARQ 프로세스에 속한 TB들에 대한 서로 다른 PDSCH를 스케줄링하기 위한 것일 수 있다. 또한, 상기 제1 DCI 및 제2 DCI는 시간 윈도우 내에서 상기 기지국으로부터 수신될 수 있다.
