Abstract [en]

We propose a non-cooperative power allocation scheme for cellular systems using soft frequency reuse and in the power control, each user selfishly maximizes its utility.To find the tradeoff between QoS satisfaction and energy consumption, we design a utility function that considers both QoS requirements and the cost. We then show there exists a Nash equilibrium and provide conditions to assure its uniqueness. This scheme has limited signaling overhead and only pricing information needs to be exchanged among cells. Simulation results show that this scheme improves throughput and coverage performance compared with conventional SFR schemes.
