Abstract
(EN)
A method for transmitting and receiving a signal in a wireless communication system according to an embodiment of the present invention, comprises the steps of: setting, by a first transmission point, a frequency resource area in at least one subframe; and transmitting information related to the set frequency resource area to a second transmission point, wherein when the first transmission point transmits a physical downlink shared channel (PDSCH) in the set frequency resource area, a ratio of a PDSCH energy per resource element (EPRE) to a cell-specific reference signal (CRS) EPRE in the set frequency resource area is less than a ratio of a PDSCH EPRE to a CRS EPRE in resource areas other than the set frequency resource area.
(FR)
Selon un mode de réalisation, la présente invention concerne un procédé permettant de transmettre et de recevoir un signal dans un système de communication sans fil, comprenant les étapes consistant à : définir, par un premier point de transmission, une zone de ressources de fréquences dans au moins une sous-trame ; et transmettre des informations liées à la zone de ressources de fréquences définie à un second point de transmission. Lorsque le premier point de transmission transmet un canal physique partagé en liaison descendante (PDSCH) dans la zone de ressources de fréquences définie, un rapport d'un élément de ressources par énergie PDSCH (EPRE) par rapport à un signal de référence spécifique à une cellule (CRS) EPRE dans la zone de ressources de fréquences définie est inférieur à un rapport d'un EPRE PDSCH par rapport à un EPRE CRS dans des zones de ressources autres que la zone de ressources de fréquences définie.
