Abstract

In this paper, we propose a green radio resource allocation (GRRA) scheme for LTE-A downlink systems with coordinated multi-point (CoMP) transmission to support multimedia traffic. It is a crucial issue to find a balance between throughput maximization and transmission power minimization, especially when the QoS requirement guarantee for multimedia traffic is considered. The GRRA scheme defines a green radio utility function by considering required transmission power, assigned modulation order, and coordinated transmission nodes. Based on this utility function, it coordinates transmission nodes to deliver data on suitable subchannels with suitable transmission power. Simulation results show that, the GRRA scheme can save the transmission power by 33.9% and 40.1%, as compared to the adaptive radio resource allocation scheme [5] with CoMP and the utility-based radio resource allocation scheme [6] with CoMP, respectively. Besides, it enhances the system throughput by 5.5% and improves the Jain fairness index for best effort users by 155% over these two schemes.
