Application: Methods, apparatuses and systems for ephemeris assisted cell selection and reselection (Patent ID: US20230388875A1)

The patent filed by ZTE Corp. discloses methods, apparatus, and systems for cell selection or reselection in a non-terrestrial network (NTN) based on ephemeris and configuration information. The method involves obtaining configuration information related to candidate cells and satellites, selecting criteria such as distance, valid time, or serving time, ranking candidate cells based on the criteria, and selecting the cell with the highest rank. The configuration information can determine candidate cells, adjust rankings, and be broadcast as system information or via Radio Resource Control (RRC) signaling.

Furthermore, the method includes obtaining ephemeris information associated with satellites, calculating criteria values based on this information, and adjusting rankings accordingly. The ephemeris information can include orbital parameters, state vectors, cell information, and beam information. Additionally, the patent covers the pre-configuration of ephemeris information in wireless communication devices, the broadcast of information by the NTN, and the selection of criteria based on configuration information. Overall, the patent aims to optimize cell selection and reselection in NTN networks through the use of detailed configuration and ephemeris data.
