Abstract
IEEE 802.16e is a promising system to provide broadband wireless access for wide area mobile communications. As the enhanced version of IEEE 802.16, with the mobility support, it becomes a potential candidate to satisfy the requirements of high data rate and wide coverage in the next generation wireless communication system. However, the handover procedures specified by the standard may cause large handover delay, which would not be suitable for the service of real-time applications. To improve the system performance and reduce the handover delay, several fast handover schemes have been proposed. In this chapter, an overview of the basic handover modes and the handover procedure defined in the standard IEEE 802.16e is presented. Some fast handover schemes, which have been proposed to reduce the handover latency, are reviewed. A more complex relay system and the corresponding new MAC frame structure to support the network relay are discussed. A handover scheme to reduce the handover latency in the WiMax relay system is summarized. The concept to construct a moving network and the fast handover scheme to support the network mobility is discussed.
