Abstract:
1. A method of transmitting and receiving a signal for a relay station in a wireless communication system, the method comprising: transmitting a signal to a user equipment through an access downlink transmission subframe; and receiving a backhaul downlink signal, transmitted from a base station through a backhaul downlink transmission subframe, through a backhaul downlink reception subframe, wherein the backhaul downlink reception subframe comprises 14 orthogonal frequency division multiplexing (OFDM) symbols and the 14 OFDM symbols are indexed 0 to 13, and wherein if the access downlink transmission subframe and the backhaul downlink transmission subframe are transmitted with time aligned subframe boundary, OFDM symbols having indices K to 12 are used for receiving the backhaul downlink signal, where K is a natural number and 1≦K≦3.
