Claim:
A method of transmitting feedback information at a mobile subscriber station (MSS) in a broadband wireless access system, the method comprising: transmitting the feedback information in a feedback header which does not contain a payload to a base station when the MSS needs to transmit the feedback information as an unsolicited feedback, wherein the feedback header is transmitted using uplink radio resources which have previously been allocated or using uplink radio resources allocated by the base station in response to a request for uplink radio resources allocation, wherein the request for uplink radio resources allocation is performed either by transmitting an indication flag on a fast feedback channel or an enhanced fast feedback channel or transmitting a bandwidth request code to the base station, wherein a connection identifier (CID) is included in the feedback header only when the feedback header is transmitted using the uplink radio resources allocated in response to the request for uplink radio resources allocation performed by transmitting the bandwidth request code to the base station.
