Method and device for tracking synchronization

Provided are a method and device for tracking synchronisation between apparatuses in a wireless communication system. A receiving apparatus receives, from a transmitting apparatus, a tracking signal in a subframe, and the received tracking signal is used in order to estimate the timing offset between the transmitting apparatus and the receiving apparatus. The tracking signal is received in the last OFDM symbol of the subframe, and the last OFDM symbol contains a sequence that is repeated N (N>1) times.
