IEEE 802.16 standard was designed to support the bandwidth demanding applications with Quality of Service (QoS). Bandwidth is reserved for each application to ensure the QoS. For Variable Bit Rate (VBR) applications, however, it is difficult for the Subscriber Station (SS) to predict the amount of incoming data. To ensure the QoS guaranteed services, the SS may calculate more bandwidth. In this paper, the authors propose a scheme, named bandwidth calculation, to calculate the bandwidth without changing the existing unused calculates bandwidth.
