Abstract

The mobile station for transceiving signals using a predetermined time division duplex (TDD) frame structure in a wireless communication system includes a receiver for receiving a midamble from a base station (BS), and a relay station (RS). The receiver receives, from the BS, a first midamble through a second subframe of a downlink access zone of the BS and/or through a first subframe of a downlink relay zone that follows the downlink access zone. Alternatively, the receiver receives, from the RS, a second midamble through a second subframe of a downlink access zone of the RS. A transition gap in a downlink region is located in the last subframe of the downlink access zone of the RS, which follows the downlink access zone of the RS, and a transition gap in an uplink region is located in a first subframe of an uplink relay zone of the RS.

Claims

1. A method for transceiving signals using a predetermined time division duplex (TDD) frame in a wireless communication system the method comprising,

transmitting, a first midamble by a base station (BS) to a mobile station (MS);

and

transmitting a second midamble by the BS to a relay station (RS),

wherein the first midamble is transmitted through a downlink access zone of the BS,

wherein the second midamble is transmitted through a downlink relay zone of a specific frame of each superframe,

wherein the second midamble is transmitted through a last symbol of a first non-type-3 subframe of the downlink relay zone counting from an end of a downlink zone of the specific frame, and

wherein a channel bandwidth of the TDD frame is either 5 MHz, 10 MH or 20 MHz.

2. The method according to claim 1, wherein a CP (Cyclic Prefix) length of each symbol corresponds to 1/16 or ⅛

of an effective symbol length in the TDD frame.

3. A base station (BS) configured to transceive signals using a predetermined TDD frame in a wireless communication system, the BS comprising:

a transmitter configured to transmit a first midamble to a mobile station (MS) and transmit a second midamble to a relay station (RS),

wherein the first midamble is transmitted through a downlink access zone of the BS,

wherein the second midamble is transmitted through a downlink relay zone of a specific frame of each superframe,

wherein the second midamble is transmitted through a last symbol of a first non-type 3 subframe of the downlink relay zone counting from an end of a downlink zone of the specific frame, and

wherein a channel bandwidth of the TDD frame is either 5 MHz, 10 MH or 20 MHz.

4. The BS according to claim 3, wherein a CP (Cyclic Prefix) length of each symbol corresponds to 1/16 or ⅛

of an effective symbol length in the TDD frame.

5. A method for transceiving signals using a time division duplex (TDD) frame of the RS in a wireless communication system, the method comprising,

transmitting a first midamble by a relay station (RS) to a mobile station (MS);

and

receiving a second midamble by the RS from a base station (BS),

wherein the first midamble is transmitted through a downlink access zone of the RS,

wherein the second midamble is received through a downlink relay zone of a specific frame of each superframe,

wherein the second midamble is received through a last symbol of a first non-type-3 subframe of the downlink relay zone counting from an end of a downlink zone of the specific frame, and

wherein a channel bandwidth of the TDD frame is either 5 MHz, 10 MH or 20 MHz.

6. The method according to claim 5, wherein a CP (Cyclic Prefix) length of each symbol corresponds to 1/16 or ⅛

of an effective symbol length in the TDD frame.

7. A relay station (RS) for transceiving signals using a time division duplex (TDD) frame of the RS in a wireless communication system, the RS comprising,

a transmitter configured to transmit a first midamble to a mobile station (MS);

and

a receiver configured to receive a second midamble from a base station (BS),

wherein the first midamble is transmitted through a downlink access zone of the RS,

wherein the second midamble is received through a downlink relay zone of a specific frame of each superframe,

wherein the second midamble is received through a last symbol of a first non-type-3 subframe of the downlink relay zone counting from an end of a downlink zone of the specific frame, and

wherein a channel bandwidth of the TDD frame is either 5 MHz, 10 MH or 20 MHz.

8. The RS according to claim 7, wherein a CP (Cyclic Prefix) length of each symbol corresponds to 1/16 or ⅛

of an effective symbol length in the TDD frame.
