Apparatus and method for communicating frames in multi-hop relay broadband wireless access communication system
First Claim
1. A method for communicating at a Relay Station (RS) in a multi-hop relay cellular communication system, the method comprising the steps of:
- receiving a Downlink (DL) signal from a Base Station (BS) and reconfiguring the received DL signal during a first section of a frame; and
transmitting the reconfigured DL signal to a Mobile Station (MS) during a second section of the frame.

Abstract
Provided is an apparatus and method for communicating a frame in a multi-hop relay cellular communication system. When communicating at a Relay Station (RS), a Downlink (DL) signal is received from a Base Station (BS) and the received DL signal is reconfigured during a first section of a frame. The reconfigured DL signal is transmitted to a Mobile Station (MS) during a second section of the frame. During a third section of the frame, a UL signal is received from the MS and is reconfigured. The reconfigured UL signal is transmitted to the BS during a fourth section of the frame. The RS recovers data from the BS to retransmit only specific data corresponding to the BS. Accordingly, unnecessary retransmission can be prevented and thus resources can be used efficiently.

9. A Relay Station (RS) for a multi-hop relay cellular communication system, comprising:
-
a recoverer for recovering a control channel message and traffic data from a first section signal of a frame received from a Base Station (BS);
a analyzer for analyzing the control channel message to select traffic data to be relayed by the RS; and
a control channel reconfigurer for allocating resources to the selected traffic data and reconfiguring the control channel message according to the resource allocation. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for communicating at a Base Station (BS) in a multi-hop relay cellular communication, the method comprising the steps of:
-
determining where DL data needs to be transmitted through a Relay Station (RS) when the DL data is generated;
generating a channel allocation message including identification (ID) information of a corresponding RS if the DL data needs to be transmitted through the RS; and
configuring and transmitting a DL signal including the channel allocation message and the DL data. - View Dependent Claims (16)

17. A method for communicating a frame in a multi-hop relay cellular communication system, the method comprising the steps of:
-
transmitting a signal from a Base Station (BS) to a relay station (RS) and a near Mobile Station (MS) during a first section of the frame;
transmitting a signal from the RS to a far MS during a second section of the frame;
transmitting a signal from the far MS to the RS during a third section of the frame; and
transmitting a signal from the near MS and the RS to the BS during a fourth section of the frame. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
