1. An apparatus to be used in a user equipment (UE), the apparatus comprising:
processing circuitry, wherein to configure the UE for reporting on Reference Signal Time Difference (RSTD)-based 5G-New Radio (NR) positioning, the processing circuitry is to:
determine a first positioning reference signal (PRS) bandwidth (BW) associated with a first PRS received from a first Next Generation Node-B (gNB), the first gNB associated with a first cell;
determine a second PRS BW associated with a second PRS received from a second gNB, the second gNB associated with a second cell;
determine an RSTD report resolution based on the first PRS BW and the second PRS BW;
measure a receive (Rx) timing difference between the first cell and the second cell based on reception times of the first PRS and the second PRS; and
map the measured Rx timing difference into an RSTD report for transmission to the first gNB, based on the RSTD report resolution; and
a memory coupled to the processing circuitry and configured to store the first PRS BW and the second PRS BW.
