Joint Optimization of Quality of Experience and Power Consumption in OFDMA Multicell Networks. |
Abstract | ||
|---|---|---|
Quality of experience (QoE) and power consumption are two important considerations of OFDMA multicell networks. In this letter, we propose a fair QoE-based radio resource allocation (FQRA) for OFDMA multicell networks. Different from the previous work, the multiuser QoE per power consumption is introduced as the performance metric. A novel utility function, which can characterize the fairness of users' QoE and power consumption jointly, is proposed. Then a multiuser FQRA problem is formulated. Due to the nonconvex form of optimization, a two-step solution is devised in which the subchannel allocation and power allocation are performed iteratively. Simulation results show that our method can significantly improve the QoE per power consumption of cells and outperform the state-of-art schemes. |
