Conference Title: GLOBECOM 2018 - 2018 IEEE Global Communications Conference Conference Start Date: 2018, Dec. 9 Conference End Date: 2018, Dec. 13 Conference Location: Abu Dhabi, United Arab Emirates In this paper, we study the problem of Quality of Experience $(\mathbf{QoE})$ aware resource allocation in wireless systems. In particular, we consider application-aware joint Bandwidth-Power allocation for a small cell. We optimize a QoE metric for multi-user video streaming in a small cell that maintains a trade-off between maximizing the playback rate of each user and ensuring proportional fairness (PF) among users. We formulate the application-driven joint bandwidth-power allocation as a non-convex optimization problem. However, we develop a polynomial complexity algorithm, and we show that the proposed algorithm achieves the optimal solution of the proposed optimization problem. Simulation results show that the proposed QoE-aware algorithm significantly improves the average QoE. Moreover, it outperforms the weighted sum rate allocation which is the state-of-the-art physical resource allocation scheme.
