Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/107090
Kind Code:
A1
Abstract:
The present invention is provided with: a reception unit which receives PTRS-UplinkConfig and Downlink Control Information (DCI) format; and a transmission unit which transmits Physical Uplink Shared Channel (PUSCH) and Phase Tracking Reference Signal (PT-RS) on the basis of the PTRS-UplinkConfig and the value of a Frequency Domain Resource Assignment (FDRA) field included in the DCI format. The transmission unit does not transmit the PT-RS in the case when the value of the FDRA field shows that the bandwidth scheduled for the PUSCH is smaller than 1 Physical Resource Block (PRB) while transform precoding is enabled, but transmits the PT-RS together with the PUSCH in the case when the FDRA field value shows that the bandwidth scheduled for the PUSCH is less than 1 PRB and a higher-layer parameter is set up, indicating that coverage enhancement is enabled.
