Application: Reporting accuracy of timing and frequency synchronization associated with communications between a non-terrestrial node and a terrestrial node (Patent ID: US20240163815A1)
The patent filed by Sharp Corp. describes a method for a user equipment (UE) to communicate with a non-terrestrial network (NTN) node by transmitting parameters to a ground-based base station (BS) for indicating the accuracy of time and frequency synchronization between the UE and the NTN node. The parameters are transmitted through various channels like uplink control information, periodic Channel State Information reports, Medium Access Control Control Elements, and Physical Uplink Control Channels.
The method involves the ground-based BS using the parameters received from the UE to reconfigure the UE for adjusting time and frequency synchronization, especially in scenarios like changes in propagation delay due to distance variations, Doppler shift caused by velocity differences, or Global Navigation Satellite System (GNSS) outages. The UE performs a time and frequency synchronization process before transmitting the parameters, which can be based on GNSS, Doppler, propagation delay measurements, or interpolation, and the transmission of parameters is triggered by events like periodic triggers, GNSS outages, or uplink data arrivals. The BS plays a crucial role in enabling the transmission of parameters and using them to reconfigure the UE for optimal communication with the NTN node.
