Abstract
(EN)
The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. In addition, the present disclosure relates to a method and device for carrying out cooperative communication in a wireless communication system. A method of a terminal of a communication system, according to one embodiment of the present disclosure, comprises the steps of: receiving, from a base station associated with a first cell, cell configuration information including a TCI configuration and a QCL configuration; checking a QCL reference antenna port on the basis of the cell configuration information; and receiving a signal from the base station on the basis of a QCL relationship with the checked QCL reference antenna port, wherein the QCL reference antenna port may be checked on the basis of a CSI-RS or SSB associated with a second cell.

La présente invention concerne une technique de communication destinée à faire converger une technologie de l'IoT avec un système de communication 5G pour prendre en charge un débit de transmission de données supérieur à celui d'un système 4G, et un système associé. La présente invention peut être appliquée à un service intelligent (par exemple, une maison intelligente, un bâtiment intelligent, une ville intelligente, une voiture intelligente ou une voiture connectée, des soins de santé, l'éducation numérique, le commerce de détail, un service associé à la sûreté et à la sécurité, etc.) sur la base de la technologie de communication 5G et de la technologie liée à l'IoT. De plus, la présente invention concerne un procédé et un dispositif pour réaliser une communication coopérative dans un système de communication sans fil. Un procédé d'un terminal d'un système de communication, selon un mode de réalisation de la présente invention, comprend les étapes de : réception, à partir d'une station de base associée à une première cellule, d'informations de configuration de cellule comportant une configuration TCI et une configuration QCL ; vérification d'un port d'antenne de référence QCL sur la base des informations de configuration de cellule ; et réception d'un signal à partir de la station de base sur la base d'une relation QCL avec le port d'antenne de référence QCL vérifié, le port d'antenne de référence QCL pouvant être vérifié sur la base d'un CSI-RS ou SSB associé à une seconde cellule.
