  In this paper, we study the problem of Quality of Experience (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.
