Network Entry, Initialization and Ranging

Both the IEEE 802.16-2009 standard and the IEEE 802.16m amendment define procedures for network entry, initialization and ranging. These procedures configure connectivity parameters, achieve synchronization and enable power control for both MSs and RSs. The IEEE 802.16m extends these procedures through refining the definitions of the different operational states of network entities.

This Chapter is organized is organized as follows. Section 5.1 discusses network entry, initialization and ranging in the point-to-multipoint model of IEEE 802.16-2009. In addition to the OFDMA interface, the section briefly touches on ranging in OFDM given its relevance to understanding the procedure. Section 5.2 elaborates an entry, initial ranging and periodic ranging in the multihop relay amendment, IEEE 802.16j-2009. Finally, Section 5.3 discusses network entry the WiMAX IMT-Advanced amendment, IEEE 80.216m.
