METHOD OF PROVIDING LOW-COMPLEXITY LONG TERM EVOLUTION- DEVICE TO DEVICE (LTE-D2D) SYNCHRONIZATION ALGORITHMS IN LTE D2D COMMUNICATIONS

摘要

ABSTRACT METHOD OF PROVIDING LOW-COMPLEXITY LONG TERM EVOLUTION- DEVICE TO DEVICE (LTE-D2D) SYNCHRONIZATION IN LTE D2D COMMUNICATIONS The various embodiments of the present invention discloses a method of providing low-complexity Long Term Evolution-Device to Device (LTE-D2D) Synchronization in LTE D2D Communications. The method comprises of estimating, by a User Device, a symbol time based on Primary Sidelink Synchronization Signal, verifying if the PSSS symbol start timing is exhausted, refining a PSSS correlation if the PSSS symbol start timing is not exhausted, correcting a frequency offset for the PSSS symbols, estimating a channel on the PSSS based on a detected PSSS ID, equalizing a secondary side link synchronization signal (SSSS) symbols to determine a frequency offset having a high value, determining a sidelink identity (NID_SL) along with a symbol time and the frequency offset, validating the NID_SL, adding the validated NID_SL to a list of optimum frequency offset and terminating synchronization of the LTE D2D devices at the validated NID_SL frequency offset.
