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.
