MOBILITY IN NON-TERRESTRIAL NETWORKS WITH EARTH MOVING CELLS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18186800 titled 'MOBILITY IN NON-TERRESTRIAL NETWORKS WITH EARTH MOVING CELLS

Simplified Explanation

The patent application is about methods and apparatuses for mobility in a wireless communication system with earth moving cells in a non-terrestrial network.

• The method involves a UE (User Equipment) receiving cell-moving information for a serving cell or neighbor cells.
• The cell-moving information includes the coordinates of a reference location and the velocity of that location at a specific time.
• The UE determines if any of the serving cell or neighbor cells are earth-moving cells.
• If an earth-moving cell is identified, the UE updates the coordinates of the reference location for that cell using the cell-moving information and ephemeris information.
• The UE then calculates the distance between itself and the updated coordinates of the reference location.
• Based on this distance, the UE decides whether to measure signals from the neighbor cells for a cell reselection operation.

Original Abstract Submitted

Methods and apparatuses for mobility in non-terrestrial network with earth moving cells in a wireless communication system. A method of a UE comprises: receiving, for a serving cell or neighbor cells, first cell-moving information including first coordinates of a first reference location at a first epoch time and a velocity of the first reference location; determining whether at least one of the serving cell or the neighbor cells is an earth-moving cell; updating, using the first cell-moving information and ephemeris information, the first coordinates of the first reference location for at least one of the serving cell or the neighbor cells based on a determination that the at least one of the serving cell or the neighbor cells is the earth-moving cell; identifying a distance between the UE and the first coordinates of the first reference location; and determine, based on the distance, whether to measure signals received from the neighbor cells for a cell reselection operation.
