Sidelink positioning based on PRS transmission of single user equipment in NR V2X

A first device for performing wireless communication, the first device 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:
• transmit, to a plurality of second devices, at least one positioning reference signal (PRS);
• receive, from the plurality of second devices, location information of the plurality of second devices and time of arrival (TOA) values of the plurality of second devices;
• and
• determine a location of the first device based on the location information of the plurality of second devices and the TOA values of the plurality of second devices,
• wherein the TOA values are determined based on the time when the plurality of second devices received the at least one PRS.

A device configured to control a first user equipment (UE), the device comprising:

• one or more processors;
• and
• one or more memories being operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
• transmit, to a plurality of second UEs, at least one positioning reference signal (PRS);
• receive, from the plurality of second UEs, location information of the plurality of second devices and time of arrival (TOA) values of the plurality of second UEs;
• and
• determine a location of the first device based on the location information of the plurality of second UEs and the TOA values of the plurality of second UEs,
• wherein the TOA values are determined based on the time when the plurality of second UEs received the at least one PRS.
