Abstract: PURPOSE: A method for transmitting a bandwidth request message to a base station in a wireless broadband system, a terminal, and the base station are provided to transmit a bandwidth assignment request message from the terminal to the base station in order to control bandwidth assignment between terminals. CONSTITUTION: A terminal transmits a first bandwidth request message to a base station by using a first polling section(S503). The terminal senses a collision with a bandwidth request message of other terminals(S504). When the collision is sensed, the terminal transmits a second bandwidth request message to the base station by using the first polling section and a second polling section(S506). The first polling section is a multicast polling section. The second polling section is a broadcast polling section.
