Bandwidth request method and bandwidth allocation method in broadband wireless access system

The present invention deals with a method for requesting and allocating an uplink resource efficiently in a broadband wireless access system. The method of the present invention wherein a terminal requests bandwidth in a broadband wireless access system may include a step in which a bandwidth request header (BR header), including a bandwidth request message and a high-speed access message, is transmitted to a base station; a step in which uplink grant (UL grant) information corresponding to the information included in said bandwidth request message and said high-speed access message is received from said base station; and a step in which the uplink resource indicated by said uplink grant information is used to transmit data to said base station.
