BASE STATION DEVICE, TERMINAL DEVICE AND COMMUNICATION METHOD THEREFOR

Title:

BASE STATION DEVICE, TERMINAL DEVICE AND COMMUNICATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/131021

Kind Code:

A1

Abstract:

This terminal device communicates with a base station device, and is provided with: a wireless reception unit that receives a CSI reference signal; a control unit that calculates channel state information (CSI); and a transmission unit that transmits the CSI, wherein the control unit calculates the CSI on the basis of an RRC parameter relating to the number of repetitions if a transport block error rate used for calculating the CSI is set from an upper layer processing unit, and calculates the CSI independent of the RRC parameter relating to the number of repetitions if the transport block error rate used for calculating the CSI is not set from the upper layer processing unit.
