Abstract:
1. A method for requesting a bandwidth by a mobile station (MS) in a wireless communication system, the method comprising: receiving a message from a base station (BS), wherein the message includes information indicating whether or not the BS automatically allocates an additional bandwidth caused by a signaling overhead for a fragmented protocol data unit (PDU) without a request for the additional bandwidth; requesting a first bandwidth, required to transmit a first PDU, from the BS; receiving an allocation of a second bandwidth less than the first bandwidth from the BS; fragmenting the first PDU according to the second bandwidth to generate a second PDU and a third PDU; transmitting the second PDU through the second bandwidth to the BS; and starting a first timer upon receiving the allocation of the second bandwidth or upon transmitting the second PDU if the information indicates that the BS automatically allocates the additional bandwidth; wherein the message corresponds to a registration response (REG-RSP) message or a ranging response (RNG-RSP) message.
