FREQUENCY ADJUSTMENT FOR NON-TERRESTRIAL NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18602758 titled 'FREQUENCY ADJUSTMENT FOR NON-TERRESTRIAL NETWORKS
Simplified Explanation
This patent application discloses systems and methods for adjusting frequencies in a wireless network, specifically a Non-Terrestrial Network (NTN). It includes a method for compensating for Doppler shifts and timing drift in the network.
- Obtaining a characterization of Doppler variations in a specific cell from a network node.
- Tuning the local frequency reference of a User Equipment (UE) to a received downlink frequency for the cell.
- Adjusting the local frequency reference over time based on the pre-calculated Doppler variations.
- Enabling communication between the UE and the network node in the presence of large and varying Doppler shifts.
Potential Applications
This technology can be applied in satellite communication systems, mobile networks, and other wireless communication systems where Doppler shifts and timing drift need to be compensated for.
Problems Solved
This technology addresses the challenges of maintaining stable communication in wireless networks where Doppler shifts and timing drift can affect signal quality and reliability.
Benefits
- Improved communication reliability in wireless networks. - Enhanced performance in Non-Terrestrial Networks. - Better user experience with reduced signal interference.
Commercial Applications
Frequency adjustment technology like this can be valuable for satellite communication providers, mobile network operators, and companies deploying wireless networks in challenging environments.
Questions about Frequency Adjustment in Wireless Networks
How does frequency adjustment help in compensating for Doppler shifts in a wireless network?
Frequency adjustment helps in compensating for Doppler shifts by tuning the local frequency reference of User Equipment to match the received downlink frequency, enabling stable communication despite varying Doppler effects.
What are the potential implications of this technology for satellite communication systems?
This technology can significantly improve the performance and reliability of satellite communication systems by mitigating the impact of Doppler shifts and timing drift, leading to better signal quality and overall network efficiency.
Original Abstract Submitted
Systems and methods are disclosed herein for frequency adjustment in a wireless network, particularly a Non-Terrestrial Network (NTN). Embodiments of a method performed by a User Equipment (UE) are disclosed. In one embodiment, a method performed by a UE for compensating for a Doppler shift in a wireless network comprises obtaining, from a network node, a characterization of Doppler variations in a particular cell. The method further comprises tuning a local frequency reference, f, of the UE to a received downlink frequency for the particular cell and adjusting the local frequency reference, f, over time according to the pre-calculated characterization of Doppler variations in the particular cell. In this manner, the communication between the UE and the network node in the presence of large and varying Doppler shifts is enabled. Embodiments related to compensating for timing drift are also disclosed.
