Abstract: A method for relaying data in a wireless communication system is provided to apply a repeat function for a MAP and broadcast information that every user in a cell can recognize dynamic broadcast information and the MAP. An RS(Relay Station) receives a downlink frame from a BS(Base Station). The RS checks the received frame and confirms signal length information to be repeated. In this case, the RS confirms the MAP length information contained in the FCH(Frame Control Head) of the received frame. Then the RS repeats a section corresponding to the signal length information. At this moment, the RS repeats the MAP section of the received frame.
