A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.

Modified handover procedures for earth fixed and earth mobile beams

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.
