Abstract:
Techniques discussed herein facilitate cell selection and/or reselection in scenarios involving one or more Non-Terrestrial Network (NTN) cells. One example embodiment is a User Equipment (UE) device comprising a processor configured to perform operations comprising: determining one or more suitable cells for one of a cell selection procedure or a cell re-selection procedure, wherein the one or more suitable cells comprise a first cell associated with a satellite of a NTN; determining a ranking for each cell of the one or more suitable cells, wherein the ranking for the first cell is based at least in part on a location of the UE, ephemeris data of the satellite, and one or more additional parameters; selecting a highest ranked cell of the one or more suitable cells based on the determined rankings for each cell of the one or more suitable cells; and camping on the highest ranked cell.
