Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/225656
Kind Code:
A1
Abstract:
The purpose of the present invention is to make an appropriate determination concerning a phase tracking reference signal (PTRS) transmission power. A user terminal according to an embodiment of the present disclosure comprises: a reception unit which receives a physical downlink shared channel (PDSCH) and a phase tracking reference signal (PTRS); and a control unit which assumes that the transmission power of the PTRS is scaled on the basis of the ratio, corresponding to the value of a higher layer parameter, of a PDSCH energy per resource element (EPRE) and a PTRS EPRE. The user terminal is characterized in that at least one set of the ratio corresponding to the value of the higher layer parameter consists only of the values of the ratio less than or equal to a predetermined value.
