Method and apparatus for transmitting and receiving backhaul subframe channel in wireless communication system

A backhaul subframe channel reception method of a relay in a mobile communication system, comprising:

• receiving a downlink relay control channel in a first slot of a semi-static resource region allocated to the relay;
• checking relay backhaul data information using the downlink relay control information;
• and
• receiving backhaul data using the downlink relay control information.

A base station for transmitting a backhaul subframe in a mobile communication system, comprising:

• a relay control channel generator which generate a downlink relay control channel by encoding downlink relay control information to be transmitted to a relay;
• a controller which maps the downlink relay control channel to first slot of semi-static resource region allocated to the relay;
• a relay data generator which generates a relay data channel to be transmitted to a relay;
• a multiplexer which multiplexes reference signal, the downlink relay control channel signal, and the relay data channel signal;
• and
• a transmitter which transmits the backhaul subframe including the downlink relay control channel to the relay.

A relay for receiving a backhaul subframe in a wireless communication system, comprising:

• a channel estimator which estimate a backhaul channel using a reference signal included in the received backhaul subframe;
• a relay control channel receiver which receives a downlink relay control channel in a first slot of semi-static resource region allocated to the relay;
• and
• a relay data channel receiver which receives backhaul data using downlink relay control information included in the received downlink relay control channel.
