Title:
BASE STATION DEVICE, TERMINAL DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/156085
Kind Code:
A1
Abstract:
The purpose of the present invention is to stabilize communication quality and thus improve frequency usage efficiency or throughput by a base station device with a function of performing communication using a plurality of beams implementing appropriate beam forming while reducing interfering power. This base station device performs communication with a terminal device, and is provided with: a transmission unit that transmits a synchronization signal block including synchronization signals within a predetermined transmission window; and a control unit that sets the size of the predetermined transmission window within which the synchronization signal block is transmitted. The transmission unit notifies the terminal device of information associated with QCL between the synchronization signal blocks transmitted in the predetermined transmission window.
