USER EQUIPMENT POSITIONING BASED ON A NON-TERRESTRIAL COMMUNICATION NETWORK - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17726919 Titled 'USER EQUIPMENT POSITIONING BASED ON A NON-TERRESTRIAL COMMUNICATION NETWORK'
Simplified Explanation
The abstract describes techniques for determining the position of a user equipment (UE) in a non-terrestrial network (NTN). By measuring reference signals (RS) sent between the UE and a satellite or terrestrial base station, a device can calculate a doppler measurement and a range measurement. These measurements are then reported to a location server, which uses them to calculate the position of the UE on the earth's surface.
Original Abstract Submitted
Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.
