Abstract
(EN)
The present invention relates to a wireless communication system. More particularly, in a method for receiving a downlink signal in a wireless communication system and an apparatus for same, the present invention relates to a method and an apparatus for same, comprising the steps of: receiving a subframe including a plurality of OFDM symbols; monitoring a plurality of search spaces which are configured on the subframe, so as to receive a PDCCH which is indicated to a terminal; and performing an operation in accordance with a PDCCH which is detected when the PDCCH that is indicated to the terminal is detected, wherein each of the search spaces is configured on a first resource region and/or a second resource region, in accordance with a predetermined condition, and the first resource region and the second resource region are separated with a specific OFDM symbol as a boundary on a time domain.

La présente invention se rapporte à un système de communication sans fil. Plus particulièrement, dans un procédé permettant de recevoir un signal de liaison descendante dans un système de communication sans fil et dans un appareil pour ce dernier, la présente invention se rapporte à un procédé et à un appareil pour ce dernier, comprenant les étapes consistant à : recevoir une sous-trame qui comprend une pluralité de symboles de multiplexage orthogonal par division de fréquence (OFDM) ; surveiller une pluralité d'espaces de recherche qui sont configurés sur la sous-trame de sorte à recevoir un canal de commande de liaison descendante physique (PDCCH) qui est indiqué à un terminal ; et effectuer une opération selon un canal PDCCH qui est détecté lorsque le canal PDCCH qui est indiqué à un terminal, est détecté, chaque espace de recherche étant configuré sur une première région de ressources et/ou une seconde région de ressources selon une condition prédéterminée, et la première région de ressources et la seconde région de ressources étant séparées avec un symbole de multiplexage OFDM spécifique comme limite sur un domaine temporel.
