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.
Claims19
A method of receiving a signal by a user equipment (UE) in a wireless communication system, the method comprising:
- obtaining information regarding one or more resource blocks (RBs) for a phase tracking reference signal (PT-RS);
- and
- receiving a downlink signal including the PT-RS based on the information regarding the one or more RBs, in a state in which a size of a scheduled bandwidth for the UE is not less than a specific bandwidth,
- wherein the UE assumes that the PT-RS is present only in the state in which the size of the scheduled bandwidth for the UE is not less than the specific bandwidth, and
- wherein obtaining the information regarding the one or more RBs comprises:
- obtaining information regarding frequency density for the PT-RS based on the size of the scheduled bandwidth for the UE;
- and
- obtaining the information regarding the one or more RBs in consideration of the information regarding the frequency density for the PT-RS.
5 more elements
A wireless communication device comprising:
- a receiver;
- and
- at least one processor operably coupled with the receiver,
- wherein the at least one processor is configured to:
- obtain information regarding one or more resource blocks (RBs) for a phase tracking reference signal (PT-RS);
- and
- receive, through the receiver, a downlink signal including the PT-RS based on the information regarding the one or more RBs, in a state in which a size of a scheduled bandwidth for the wireless communication device is not less than a specific bandwidth,
- wherein the at least one processor is configured to receive the PT-RS only in the state in which the size of the scheduled bandwidth for the wireless communication device is not less than the specific bandwidth, and
- wherein in obtaining the information regarding the one or more RBs, the at least one processor is configured to obtain information regarding frequency density for the PT-RS based on the size of the scheduled bandwidth for the wireless communication device, and obtain the information regarding the one or more RBs in consideration of the information regarding the frequency density for the PT-RS.
6 more elements
A wireless communication device comprising:
- a transmitter;
- and
- at least one processor operably coupled with the transmitter,
- wherein the at least one processor is configured to:
- map a phase tracking reference signal (PT-RS) to one or more resource blocks (RBs);
- and
- transmit, to another wireless communication device through the transmitter, a downlink signal including the PT-RS mapped to the one or more RBs, in a state in which a size of a scheduled bandwidth for the another wireless communication device is not less than a specific bandwidth,
- wherein the at least one processor is configured to transmit the PT-RS to the another wireless communication device, only in the state in which the size of the scheduled bandwidth for the another wireless communication device is not less than the specific bandwidth, and
- wherein in mapping the PT-RS to the one or more RBs, the at least one processor is configured to determine frequency density for the PT-RS based on the size of the scheduled bandwidth for the another wireless communication, and determine the one or more RBs in consideration of the determined frequency density for the PT-RS.
