Interruption characteristics of distributed dynamic channel allocation with reuse partitioning and power control

Abstract

AbstractDistributed dynamic channel allocation (DDCA) schemes are important because they allow flexible handling of variations in traffic. It has been clarified by simulation that better call‐loss and interference characteristics are obtained by combining reuse partitioning and transmission power control schemes. Channel allocation and interference in DDCA are formalized in this article. It is also shown that a lower limit can be established in the signal‐to‐interference ratio (SIR) degradation caused by interference accompanying calls to other stations when channel allocation is performed such that reuse partitioning is ideally realized simultaneously. It is shown that this lower limit is described by the SIR margin and reuse partitioning characteristics and power control schemes. In addition, it is shown that the degrees of degradation in SIR of the mobile station and the base station in conversation can be predicted in advance, including the case in which reuse partitioning may not be performed ideally.
