Abstract
(EN)
The present invention relates to a method and device for operating a terminal in a wireless communication system. According to the present invention, downlink control information (DCI) is received from a base station, wherein the downlink control information includes at least one among resource information related to a resource through which a first reference signal is transmitted, port combination information related to a combination of at least one antenna port through which a second reference signal is transmitted, and quasi co-location (QCU) information between a channel through which the first reference signal is transmitted and a channel through which the second reference signal is transmitted. The present invention may provide a method and device, in which a terminal receives the second reference signal through the at least one antenna port on the basis of the DCI, wherein the at least one antenna port is included in a specific antenna port group on the basis of the resource information, and the specific antenna port group includes antenna ports multiplexed through an identical multiplexing scheme.

La présente invention concerne un procédé et un dispositif permettant d'utiliser un terminal dans un système de communication sans fil. Selon la présente invention, des informations de contrôle de liaison descendante (DCI) sont reçues d'une station de base, les informations de contrôle de liaison descendante comprenant au moins une information de ressource associée à une ressource à travers laquelle un premier signal de référence est transmis, des informations de combinaison de ports associées à une combinaison d'au moins un port d'antenne à travers lequel un second signal de référence est transmis, et des informations de quasi-colocalisation (QCU) entre un canal à travers lequel le premier signal de référence est transmis et un canal à travers lequel le second signal de référence est transmis. La présente invention peut fournir un procédé et un dispositif, dans lesquels un terminal reçoit le second signal de référence par l'intermédiaire d'un port ou de ports d'antenne sur la base des DCI, le port ou les ports d'antenne étant inclus dans un groupe de ports d'antenne spécifique sur la base des informations de ressource, et le groupe de ports d'antenne spécifique comprenant des ports d'antenne multiplexés par l'intermédiaire d'un plan de multiplexage identique.
