Publication number: 20240349217Abstract: This disclosure presents methods to compensate for a phase drift in an uplink communication signal between a user equipment (UE) and a non-terrestrial network (NTN) node. Due to the change rate of velocity of the UE relative to the NTN node, a transmission signal can drift causing demodulation errors at the receiver. The UE can apply compensation processes to the transmission signal so that the received signal is closer to the original transmitted signal as compared to a non-compensated signal. Alternatively, the NTN node can apply compensation process to modify the reference phase to be closer to the phase of the received signal in the demodulation process. The location of the UE, as well as its relative elevation, can be used with the NTN node's location, to generate the compensation information. The compensation can be applied on a symbol-by-symbol basis or to a group of M symbols.Type: ApplicationFiled: August 6, 2021Publication date: October 17, 2024Inventors: Gilsoo LEE, Tzu-Chung HSIEH, Jingyuan SUN
