Abstract:
A method for operating a device in a wireless communication system supporting Device to Device (D2D) communication system includes receiving a reference signal from each of at least one transmitting device, estimating a frequency offset between the reference signals and a comparison reference signal corresponding to the reference signals, and adjusting a transmit frequency of a voltage controlled oscillator of the device using the estimated frequency offset estimation. An apparatus for compensating for a frequency offset of a device in a wireless communication system supporting Device to Device (D2D) communication system includes a frequency offset estimator configured to receive reference signals from each of at least one transmitting device, and estimating a frequency offset between the reference signals and a comparison reference signal corresponding to the reference signals, and a voltage controlled oscillator configured to adjust a transmit frequency using the estimated frequency offset.
