Abstract

The random access scheme is used for initial and periodic ranging in the IEEE 802.16 protocol. The number of contention slots in the uplink subframe decides the system performance. However, how many contention slots should be allocated for ranging is not standardized in the protocol, so it is still necessary to determine the optimal number of contention slots. In this paper, the exact equations of the optimal numbers of initial ranging slots and periodic ranging slots are derived. An optimal dynamic allocator is also proposed to optimize the allocation of the initial and periodic ranging regions in the uplink subframe. The simulation results show that good system performance can be achieved with the optimal dynamic allocator.
