Document Type and Number:
WIPO Patent Application WO/2021/060954
Kind Code:
A1
Abstract:
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.
