Sharp had seven patents in space economy during Q1 2024. Sharp Corp has filed patents for user equipment (UE) with GNSS capabilities to estimate signal propagation delay between a non-terrestrial network (NTN) node and the UE based on Doppler frequency shift. The UE can compensate for uplink transmission delays by applying the signal propagation delay. Additionally, a wireless terminal is designed with receiving circuitry to calculate distance to a satellite slope for triggering cell reselection process.

Application: Methods and apparatuses for estimating propagation delay between a non-terrestrial node and a terrestrial node without gnss (Patent ID: US20240097777A1)
The patent filed by Sharp Corp. describes a user equipment (UE) that can estimate Doppler frequency shifts in signals received from a non-terrestrial network (NTN) node at different time instances to calculate signal propagation delays. This information is then used to compensate for uplink transmissions from the UE to the NTN node. The UE can also estimate distances between the NTN node and itself based on the Doppler frequency shifts, and can transmit information about GNSS outages to ground-based base stations.
The claims detail the specific functions of the UE and NTN node, including estimating Doppler frequency shifts, calculating signal propagation delays, and compensating for transmissions. The UE can operate without GNSS capabilities or during GNSS outages, while the NTN node can relay information about non-GNSS Doppler tracking capabilities to ground-based base stations. Overall, the patent focuses on improving communication reliability and accuracy between UEs and NTN nodes by utilizing Doppler frequency shifts and signal propagation delays for compensation and tracking purposes.
