Abstract: A framing method of fixing a training signal and a control channel for multi-link (direct link and relay link) synchronization in a multi-hop relay cellular network, and a transmitting/receiving apparatus for supporting the framing method. A base station (BS) transmits BS downlink (DL) subframe sequentially including a preamble, control information, and a DL burst to a relay station (RS) or a first mobile station (MS) connected to the BS by direct link. The RS transmits an RS DL subframe sequentially including a DL burst, a postamble, and control information to a second MS connected to the BS by relay link. Therefore, difficulties of initial synchronization, handoff, and cell search can be removed from MSs. Furthermore, multi-link bursts can be located between the preamble and the postamble by Time Division Multiplexing (TDM) or Frequency Division Multiplexing (FDM).
