Title:
BASE STATION DEVICE, TERMINAL DEVICE, COMMUNICATION METHOD AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/031701
Kind Code:
A1
Abstract:
The purpose of this invention is to provide a terminal device, a base station device, a communication method and an integrated circuit which enable efficient communication in a wireless communication system, in order to efficiently transmit channel status information. The present invention is equipped with a receiving unit which receives a PDCCH indicating a sounding reference signal request, a receiving unit which receives a reference signal for calculating channel status information, and a receiving unit for receiving a PDSCH, and if a QCL assumption used in PDSCH reception and a QCL assumption used to receive the reference signal for calculating channel status information differ from one another, a spatial domain transmission filter is applied using the previous sounding reference signal, and the sounding reference signal is transmitted.
