Joint scheduling with inter-cell cooperation for carrier aggregation in LTE-advanced system

Abstract

By investigating the technical issues in the existing cell selection and scheduling scheme under some of carrier aggregation (CA) deployment scenarios discussed in LTE-Advanced system, we propose a distributed inter-cell cooperation scheme for joint scheduling that can improve the average system throughput when 6 different sectors are formed by deploying the sector antennas for each component carrier (CC) in the different direction. It has been shown by our system-level simulation that the proposed scheme roughly doubles the per-user average throughput for the cell-edge users, i.e., ones with the lowest 5% performance when the offered load is not too large.
