Abstract

A first transparent relay station (RS) can receive a signal from a base station (BS) corresponding to superordinate node of the first transparent RS or a second RS corresponding to superordinate non-transparent RS the first transparent RS through a downlink receive zone, and the first transparent RS can transmit the signal received through the downlink receive zone to a mobile station (MS) through a downlink transmit zone, wherein a downlink subframes of the first transparent RS is located the downlink receive zone and the downlink transmit zone in order.

Claims

1. A method for transmitting and receiving signal, at a first transparent relay station (RS), in multi-hop relay system, the method comprising:

receiving a signal from a base station (BS) corresponding to superordinate node of the first transparent RS or a second RS corresponding to superordinate non-transparent RS of the first transparent RS through a downlink receive zone; and

transmitting the signal received through the downlink receive zone to a mobile station (MS) through a downlink transmit zone;

wherein downlink subframes of the first transparent RS is located the downlink receive zone and the downlink transmit zone in order.

2. A method according to claim 1, wherein downlink subframes of the second RS is located the downlink transmit zone and the downlink receive zone in order.

3. A method according to claim 2, wherein downlink subframes of BS corresponding to superordinate node of the second RS is located the downlink access zone and the downlink transmit zone in order.

4. A method according to claim 2, wherein downlink subframes of a third RS of nontransparent mode corresponding to superordinate node of the second RS is located the downlink access zone, the downlink receive zone, and downlink transmit zone in order.

5. A method according to claim 4, wherein downlink subframes of BS corresponding to superordinate node of the third RS is located the downlink access zone and the downlink transmit zone in order.

6. A method according to claim 1, wherein zone allocation information indicating a location of specific zone in downlink subframes of the RS is transmitted through a control channel of the BS or a broadcasting channel of superframe header of the BS.

7. A method according to claim 2, wherein zone allocation information indicating a location of specific zone in downlink subframes of the RS is transmitted through a control channel of the BS or a broadcasting channel of superframe header of the BS.

8. A method according to claim 4, wherein zone allocation information indicating a location of specific zone in downlink subframes of the RS is transmitted through a control channel of the BS or a broadcasting channel of superframe header of the BS.

9. A method for transmitting and receiving signal, at a first relay station (RS), in transparent mode in 2-hop relay system, the method comprising:

receiving a signal from a base station (BS) corresponding to superordinate node of the first RS or a second RS through a downlink receive zone; and

transmitting the signal received through the downlink receive zone to a mobile station (MS) through a downlink access zone;

wherein downlink subframes of the first RS is located the downlink receive zone and the downlink access zone in order.

10. A method according to claim 9, wherein a downlink subframes of the BS is located the downlink transmit zone and downlink access zone in order.

11. A method according to claim 9, wherein zone allocation information indicating a location of specific zone in downlink subframes of the RS is transmitted through at least one of a control channel of the BS and a broadcasting channel of superframe header of the BS.
