Abstract

Radio resource management techniques play a pivotal role in the quality and capacity of personal communications networks. For small cells with high user densities, future schemes will have to adapt dynamically to the rapidly changing traffic and interference. Existing systems perform several radio resource management tasks including admission control, channel assignment, power control, and handoff. This paper examines these processes simultaneously and adopts signal-to-interference ratio (SIR) as a decision criterion for handoff and admission control. Key results show that integrated radio resource management can increase system capacity within specified quality constraints. SIR is an appropriate criterion for it reflects the actual traffic conditions and channel usage patterns in the system. However, there are limitations to the use of SIR alone as an admission control criterion for reducing call dropping. The interaction of the power control and the SIR based handoff causes cell dragging and inhibits handoffs near geographical cell boundaries. This provides a motivation for future study of a handoff algorithm that is based on both SIR and transmitted power.
