Method for determining power boosting level of PTRS for removing phase noise in wireless communication system and device therefor
First Claim
1. A method for transmitting, by a base station (BS) in a wireless communication system, a phase tracking reference signal (PTRS) to a user equipment (UE) so as to enable receiver phase tracking by the UE, the method performed by the BS and comprising:
- generating the PTRS; and
transmitting the PTRS to the UE based on a PTRS power boosting level, the PTRS power boosting level being determined by the BS based on a number of Physical Downlink Shared Channel (PDSCH) layers associated with the PTRS.

Abstract
According to an embodiment of the present specification, provided is a method for transmitting a signal that allows a user equipment to cancel phase noise by a base station in an mmWave communication system. In this case, the method may include: generating a PTRS for estimating phase noise of a downlink signal; transmitting PTRS power boosting level information for the PTRS to the user equipment via downlink signaling; and transmitting the PTRS via downlink signaling based on the PTRS power boosting level information. In this case, the PTRS power boosting level information may be determined based on at least one of MCS level and PRB size.
