Title:
BASE STATION DEVICE, TERMINAL DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/130938
Kind Code:
A1
Abstract:
When a base station device or a terminal device performs transmission by beam forming and further performs carrier aggregation, quasi-colocation (QCL) is set between component carriers. The set QCL is used during calculation of channel state information (CSI). Further, on the basis of the setting of QCL between the component carriers and antenna ports, CSI of the component carriers is calculated. Further, on the basis of the number of antenna ports to be used, the CSI of the component carriers is calculated.
