MAPPING BETWEEN EPHEMERIS DATA AND CELL IDS FOR NON-TERRESTRIAL NETWORKS

摘要

An exemplary embodiment provides a method, performed by a wireless device, for linking ephemeris information to a node or cell in a non-terrestrial network, NTN. The method comprises obtaining (610) an index to ephemeris data for a satellite; and obtaining (620) at least one cell identifier or at least one node identifier associated with the obtained index to ephemeris data. The index to ephemeris data comprises an index to a sub-plane of an orbital plane divided into sub-planes. Other embodiments include a method in a network node, wireless devices, network nodes, and computer program products.
