Method for requesting and allocating upstream bandwidth in a multi-hop relay broadband wireless access communication system

A method of requesting and allocating an upstream bandwidth by a Relay Station (RS) in a wireless communication system, comprising:

• receiving, by the RS, a Code Division Multiple Access (CDMA) code indicating a requested upstream bandwidth from at least one Mobile Station (MS), respectively, for a time period;
• calculating, by the RS, a total requested upstream bandwidth by summing the requested upstream bandwidth from the at least one MS;
• generating, by the RS, a new CDMA code indicating the total requested upstream bandwidth;
• and
• sending, by the RS, the new CDMA code to a Base Station (BS).

A system for requesting and allocating an upstream bandwidth from a Relay Station (RS) in a wireless communication system, comprising:

• at least one Mobile Station (MS) for generating an upstream bandwidth request message including a requested upstream bandwidth and sending the upstream bandwidth request message to the RS;
• the RS for receiving the upstream bandwidth request message from the at least one MS for a time period, calculating a total requested upstream bandwidth by summing the requested upstream bandwidth from the at least one MS, generating a new upstream bandwidth request message including the total requested upstream bandwidth, and sending the new upstream bandwidth request message to a Base Station (BS);
• and
• the BS for allocating and scheduling the upstream bandwidth to the RS.
