Abstract

Ranging schemes have been used for timing synchronization and power control between a base station (BS) and personal subscriber stations (PSS). They are also used for bandwidth request and handoff in WiBro systems. In this paper, we present the ranging mechanism in WiBro in a view of contention resolution for ranging access. Performances of success rate and delay are assessed since they greatly affect the system capability. We investigate the performance by simulation using the parameters specified in a WiBro standard. A result shows that the average delay in ranging access is in a range of 110-700 ms depending on different scenarios.
