Analytic Hierarchy process (AHP) for Autonomous Component Carrier Selection (ACCS) in Carrier Aggregation systems

Abstract

Carrier Aggregation (CA) is one of the key technologies for Long Term Evolution Advanced (LTE-A) systems. Technology has been receiving enormous attention because of its numerous advantages particularly for bandwidth expansion to 100 MHz. One of the primary issues affecting the performance of the technology is effective component carrier selection. The selection processes become even more critical with introduction of heterogeneous network and thus require better techniques in order to reap the reality benefits of carrier aggregation. In this study, we proposed a new technique to ease the selection process for Component Carriers (CC) in an impromptu network deployment using analytic hierarchy process and Iterative water filling technique. Our simulation results show that user's throughput can be improved while maintaining low inter-cell interference among base stations.
