APPARATUS AND METHOD FOR COMMUNICATING CONTROL INFORMATION IN BROADBAND WIRELESS ACCESS SYSTEM
First Claim
1. An apparatus for transmitting control information in a Broadband Wireless Access (BWA) system using a relay scheme, the apparatus comprising:
- a scheduler for generating scheduling information by performing scheduling for a Relay Station (RS) and for determining a valid duration for the scheduling information;
a control information generator for generating a resource allocation message containing the scheduling information and the valid duration information; and
a transmitter for processing the resource allocation message in a physical layer and for transmitting the resource allocation message to the RS.

Abstract
An apparatus and method for communicating control information in a Broadband Wireless Access (BWA) system using a multi-hop relay scheme is provided. A method of transmitting control information includes generating scheduling information by performing scheduling for a Relay Station (RS); determining a valid duration for the scheduling information; generating a resource allocation message containing the scheduling information and the valid duration information; and processing the resource allocation message in a physical layer and for transmitting the resource allocation message to the RS.
