Title: METHOD FOR RECEIVING PHASE TRACKING REFERENCE SIGNAL BY TERMINAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE SUPPORTING SAME
Abstract:
The present invention relates to a method for receiving a phase tracking reference signal by a terminal, the method comprising: comparing time densities of a plurality of PT-RS ports allocated to a terminal so as to determine a highest time density value; and receiving each of PT-RSs corresponding to the plurality of PT-RS ports transmitted on the basis of the determined highest time density value, through the plurality of PT-RS ports.
