Abstract
Provided herein is a method for performing, by a first apparatus, wireless communication and an apparatus for supporting the same. The method may include the steps of generating a Phase Tracking—Reference Signal (PT-RS), transmitting a Physical Sidelink Control Channel (PSCCH) to a second apparatus, mapping, based on a Cyclic Redundancy Check (CRC) on the PSCCH, the PT-RS to a subcarrier on a Physical Sidelink Shared Channel (PSSCH) resource related to the PSCCH, and transmitting the PT-RS to the second apparatus.
Claims20
A method for performing, by a first apparatus, wireless communication, the method comprising:
- receiving, from a second apparatus, a sidelink control information (SCI) on a physical sidelink control channel (PSCCH);
- obtaining a resource block (RB) offset related to a phase tracking-reference signal (PT-RS) based on a cyclic redundancy check (CRC) on the PSCCH;
- and
- receiving, from the second apparatus, the PT-RS through a subcarrier on a physical sidelink shared channel (PSSCH) resource related to the PSCCH, based on the RB offset related to the PT-RS.
A first apparatus configured to perform wireless communication, the first apparatus comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- receive, from a second apparatus, a sidelink control information (SCI) on a physical sidelink control channel (PSCCH);
- obtain a resource block (RB) offset related to a phase tracking-reference signal (PT-RS) based on a cyclic redundancy check (CRC) on the PSCCH;
- and
- receive, from the second apparatus, the PT-RS through a subcarrier on a physical sidelink shared channel (PSSCH) resource related to the PSCCH, based on the RB offset related to the PT-RS.
An apparatus configured to control a first user equipment (UE), the apparatus comprising:
- one or more processors;
- and
- one or more memories connected to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- receive, from a second UE, a sidelink control information (SCI) on a physical sidelink control channel (PSCCH);
- obtain a resource block (RB) offset related to a phase tracking-reference signal (PT-RS) based on a cyclic redundancy check (CRC) on the PSCCH;
- and
- receive, from the second UE, the PT-RS through a subcarrier on a physical sidelink shared channel (PSSCH) resource related to the PSCCH, based on the RB offset related to the PT-RS.
