A method for requesting bandwidth in a wireless access system

A method for requesting a bandwidth in a wireless connection system is provided to avoid the collision with other terminals and reduce the time delay. A terminal transmits an MAC(Media Access Control) PDU(Protocol Data Unit) to a base station(S41). The base station transmits information about allocated resources to the corresponding terminal through a UL-MAP message(S42). The terminal transmits a BR(Bandwidth Request) header to the base station(S43). The base station assigns the resources required for transmitting data to the terminal. The base station transmits information about UL resources assigned through the UL-MAP message(S44). The terminal transmits the data through the UL resources(S45).
