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.
