A method of wireless communication of a user equipment (UE), comprising:

• receiving at least one of a number of one or more demodulation reference signal (DM-RS) symbols or one or more locations within a subframe for transmission of the one or more DM-RS symbols from a base station;
• decoding the one or more DM-RS symbols from the subframe based on the at least one of the number of the one or more DM-RS symbols or the one or more locations;
• receiving a resource allocation scheme for a phase noise compensation reference signal (PC-RS);
• and
• decoding the PC-RS from the subframe based on the resource allocation scheme for the PC-RS.
