Abstract: Systems and methods for determining channel raster(s) and synchronization signal raster(s) for New Radio (NR) unlicensed spectrum are disclosed herein. For each of a plurality of data objects an NR channel raster position is determined using Absolute Radio Frequency Channel Number (NR-ARFCN) numbers. For each corresponding NR channel. Global Synchronization Channel Numbers (GSCNs), a number of Physical Resource Blocks (PRBs) based on channel subcarrier spacing (SCS). NR channel raster position placement, channel edges, synchronization signal and physical broadcast channel (SSB) edges, and an SSB raster position are calculated. The plurality of data objects may then be down selected based on e.g., corresponding Long Term Evolution (LTE) channel raster positions and/or entries of a second plurality of data objects calculated for NR channels that use a second SCS.

Abstract: User equipment (UE) positioning within a 5G New Radio (NR) network may be determined by receiving a downlink (DL) position reference signal (PRS) resource set indicating a plurality of DL PRS resources and receiving a DL PRS report configuration that indicates a set of measurements to be performed by a UE for each of the plurality of DL PRS resources within the DL PRS resource set. Position measurements may be performed for each of the plurality of DL PRS resources within the DL PRS resource set, including generating a reference signal time difference (RSTD) measurement by estimating a timing of a first arrival path from at least two of the plurality of DL PRS resources and determining a reference signal received power (RSRP) metric or a signal to noise and interference ratio (SINR) metric associated with the at least two DL PRS resources. The performed position measurements may be reported.
