Claim 12:
13. A user equipment (UE) for receiving a phase tracking reference signal (PT-RS) in a wireless communication system, the UE comprising:
a receiver; and
a processor connected to the receiver,
wherein the processor is configured to:
receive downlink control information including a transmission configuration indication (TCI);
receive, via radio resource control (RRC) signaling, configuration information for a PT-RS; and
receive the PT-RS through a PT-RS port based on (i) a ratio of PT-RS energy per resource element (EPRE) to PDSCH EPRE per layer per RE for the PT-RS port and (ii) a TCI state,
wherein the TCI indicates the TCI state based on the configuration information, and
wherein the ratio is determined according to the configuration information based on the number of layers in a physical downlink shared channel (PDSCH).
