Abstract
The present invention discloses a method of receiving a phase tracking reference signal by a user equipment in a wireless communication system and device for supporting the same.
Claims14
A method of receiving a phase tracking reference signal (PT-RS) by a user equipment (UE) in a wireless communication system, the method comprising:
- determining a time density based on a modulation and coding scheme (MCS) for a PT-RS port;
- and
- receiving the PT-RS via the PT-RS port, based on the determined time density,
- wherein when a first PT-RS port related to a first MCS is allocated to the UE, the PT-RS is received through the first PT-RS port based on a first time density corresponding to the first MCS,
- wherein when a second PT-RS port related to a second MCS is allocated to the UE, the PT-RS is received through the second PT-RS port based on a second time density corresponding to the second MCS,
- wherein when both the first PT-RS port and the second PT-RS port are allocated to the UE, the PT-RS is received through the first PT-RS port or the second PT-RS port using only the time density corresponding to a higher MCS among the first MCS and the second MCS, and
- wherein, based on a determination that (i) a first scheduled bandwidth for the first PT-RS port is equal to a second scheduled bandwidth for the second PT-RS port, and (ii) a first power boosting level for the first PT-RS port is different from a second power boosting level for the second PT-RS port, a first PT-RS received via the first PT-RS port has a different frequency density from a second PT-RS received via the second PT-RS port.

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:
- determine a time density based on a modulation and coding scheme (MCS) for a PT-RS port;
- and
- receive the PT-RS via the PT-RS port, based on the determined time density,
- wherein when a first PT-RS port related to a first MCS is allocated to the UE, the PT-RS is received through the first PT-RS port based on a first time density corresponding to the first MCS,
- wherein when a second PT-RS port related to a second MCS is allocated to the UE, the PT-RS is received through the second PT-RS port based on a second time density corresponding to the second MCS,
- wherein when both the first PT-RS port and the second PT-RS port are allocated to the UE, the PT-RS is received through the first PT-RS port or the second PT-RS port using only the time density corresponding to a higher MCS among the first MCS and the second MCS,
- wherein a frequency density of the PT-RS is determined based on a scheduled bandwidth the first PT-RS port or the second PT-RS port and a power boosting level for the first PT-RS port or the second PT-RS port, and
- wherein when the second MCS is higher than the first MCS, one PT-RS received via the first PT-RS port is received by applying 0 dB (decibel) power boosting, 3 dB power boosting, or 6 dB power boosting thereto based on signaling.
