Abstract
Carrier aggregation in LTE-Advanced provides the capability to uncoordinatedly deploy home eNodeBs with the opportunity to autonomously mitigate the interferences. Among many improvement approaches, the autonomous component carrier selection (ACCS) scheme to improve the performance of the cell edge users worth our attentions. However, a poorly ordered execution of the carrier selection can lead to waste of radio resources in a typical home Internet access scenario. In order to address this issue, we propose a component carrier reselection scheme which ameliorates the total throughput of the eNodeBs by reselecting the carriers according to an intelligently planned order. Additionally, we also propose to improve the performance of the cell edge users with the low-complexity fractional power suppression technique. System-level simulation of the proposed schemes has shown substantial improvement over the original ACCS scheme.
