Apparatus and method for processing transmission information of broadcast message constituted by relay station (RS) in multihop relay broadband wireless access (BWA) communication system

A communication method of a Base Station (BS) in a multihop relay wireless communication system, the method comprising:

• receiving from a Relay Station (RS) a scheduling request message to request bandwidth on an RS access link for transmission of a message composed by the RS,
• determining a transmission region for the message composed by the RS using information of the scheduling request message;
• and
• transmitting to the RS an allocation message which includes information for transmission of the message composed by the RS, in response to the scheduling request message,
• wherein the scheduling request message includes the requested amount of bandwidth.

A Relay Station (RS) in a multihop relay wireless communication system, comprising:

• a message generator for generating a scheduling request message to request bandwidth on RS access link for transmission of a message composed by the RS;
• a transmitter for processing the scheduling request message output from the message generator in a physical layer and transmitting the scheduling request message to the BS;
• and
• a receiver for receiving an allocation message, which includes information for the transmission of the message composed by the RS, in response to the scheduling request message,
• wherein the scheduling request message includes the requested amount of bandwidth.
