METHODS AND APPARATUSES FOR ESTIMATING PROPAGATION DELAY BETWEEN A NON-TERRESTRIAL NODE AND A TERRESTRIAL NODE WITHOUT GNSS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18269591 titled 'METHODS AND APPARATUSES FOR ESTIMATING PROPAGATION DELAY BETWEEN A NON-TERRESTRIAL NODE AND A TERRESTRIAL NODE WITHOUT GNSS
Simplified Explanation
The patent application describes a user equipment (UE) that can estimate Doppler frequency shifts in a signal received from a non-terrestrial network (NTN) node and use this information to compensate for uplink transmission delays.
- The UE estimates Doppler frequency shifts in a signal received from an NTN node at different time instances.
- It calculates the signal propagation delay between the NTN node and the UE based on the Doppler frequency shifts.
- The UE applies the signal propagation delay to compensate for uplink transmission delays from the UE to the NTN node.
Potential Applications
This technology could be applied in satellite communication systems, where accurate estimation of signal propagation delays is crucial for maintaining reliable communication links.
Problems Solved
This technology solves the problem of compensating for signal propagation delays in non-terrestrial networks, which can improve the overall performance and reliability of communication systems.
Benefits
The benefits of this technology include improved accuracy in estimating signal propagation delays, leading to better uplink transmission performance and overall network efficiency.
Potential Commercial Applications
One potential commercial application of this technology could be in satellite communication systems for industries such as telecommunications, broadcasting, and remote sensing.
Possible Prior Art
One possible prior art for this technology could be existing methods for estimating Doppler frequency shifts in communication systems, but the specific application of compensating for uplink transmission delays in non-terrestrial networks may be novel.
=== What are the specific technical details of how the Doppler frequency shifts are estimated in the signal received from the NTN node? The specific technical details of how the Doppler frequency shifts are estimated in the signal received from the NTN node are not provided in the abstract. Further information on the algorithms or techniques used for this estimation would be necessary to fully understand the implementation of this technology.
=== How does the UE handle variations in signal strength or interference that may affect the accuracy of the estimated signal propagation delay? The abstract does not mention how the UE handles variations in signal strength or interference that may affect the accuracy of the estimated signal propagation delay. Understanding the robustness of the system in real-world conditions would be important for assessing its practical utility.
Original Abstract Submitted
A user equipment (UE) includes one or more non-transitory computer-readable media having computer-executable instructions embodied thereon, and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to: estimate a first Doppler frequency shift in a signal received from a non-terrestrial network (NTN) node at a first time instance, estimate a second Doppler frequency shift in the signal at a second time instance, estimate a signal propagation delay between the NTN node and the UE based on the first Doppler frequency shift and the second Doppler frequency shift, and apply the signal propagation delay to compensate for an uplink transmission from the UE to the NTN node.
