Abstract: A terminal synchronization method and apparatus for use in a wireless communication system are provided. A synchronization method includes configuring, at the terminal, a synchronization signal reference time depending on whether a synchronization signal is received in an initial observation period as long as at least two frames, monitoring to receive the synchronization signal in an alternation period of a transmission period and a reception period, the alternation period following the initial observation period, updating the reference time depending on whether the synchronization signal is received in the reception period, transmitting the synchronization signal at the updated reference time in the transmission period, and updating the reference time depending on whether the synchronization signal is received in a dedicated observation period following the alternation period. The synchronization apparatus and method are advantageous in that synchronization is obtained without assistance of a base station, an Access Point (AP), etc.

Abstract: A wireless communication device is provided. The wireless communication device includes: a communication circuit configured to transceive a signal using a plurality of antennas; a processor configured to: detect a first interference for N resource blocks (RB) of the signal; based on the first interference being detected, perform a first whitening validation on the first interference; detect a second interference based on a result of the first whitening validation; and based on the second interference being detected, perform a second whitening validation on the second interference; and a whitening filter circuit configured to perform whitening filtering on results of the first whitening validation and the second whitening validation.
