  • Patent number: 11910339
    Abstract: A system and a method for performing uplink (UL) time synchronization in non-terrestrial networks (NTN) include Performing Downlink (DL) synchronization SSB signals. At least one information is received by a UE 102 from an NTN BS 104. A location information of a satellite is obtained using the at least one information received by the UE 102. Location of the UE 102 is estimated using one of GNSS receiver of the UE 102 and by processing at least one reference signal received by the UE 102 from multiple NTN-BS 104, using at least one multilateration technique and RTK. Timing Advance (TA) estimate is determined using the location of the satellite and location of the UE 102. TA applied is determined using the TA estimate and TA margin. PRACH is transmitted based on the TA applied and an information related to the TA applied is reported to the NTN-BS 104. Residual TA is estimated using the reported information related to the TA applied and the detected PRACH.
