Wireless access communication system for performing ranging stage and subscriber station and base station therefor and method therein

In a wireless access communication system according to the present invention, the base station allocates a predetermined UL resource that can include at least basic TLV elements to the terminal to allocate resources to the UE in CDMA_Allocation_IE successful completion of the ranging code. That is, the base station allocates an amount of uplink resources to the resource amount that can transmit basic information of the terminal. If the terminal is not sufficient to transmit the RNG-REQ message to be transmitted uplink resource amount allocated, the mobile station to transmit a RNG-REQ message including at least the basic information to the base station, to request a bandwidth for transmitting additional Add the "Ranging status indication" information, for example, the RNG-REQ message to the terminal to inform it requires the additional RNG-REQ transmission to the base station. Ranging procedure, a ranging code
