IEEE 802.16e is an advanced wireless access technology that provides high-speed data transmission in long distance and offers Qality of Service (QoS) to subscribers. The provisioning of QoS is one of the great features by IEEE 802.16 to support both real-time and non-real-time applications. In IEEE 802.16, the common part sublayer in the MAC layer is responsible for maintaining the QoS services. There are many functions in the common part sublayer; the most popular topics discussed by researchers are the uplink and downlink scheduling algorithms. Many discussions had been made and focused on these two classes of schedulers. Another equally important component but overlooked so far is the bandwidth request and grant module.
