Title:
USER EQUIPMENT AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/225685
Kind Code:
A1
Abstract:
The purpose of the present invention is to control transmission of a phase tracking reference signal (PTRS) appropriately. A user equipment according to an embodiment of the present disclosure comprises: a control unit which, when retransmission of an upstream shared channel is performed, controls the determination of the time density of a PTRS on the basis of whether a modulation and coding scheme (MCS) index is included in a range greater than a predetermined value; and a transmission unit which performs transmission of the PTRS.
