Abstract: The main goal of future wireless networks is using wireless spectrum resources as efficently as possible and providing quality of experience guarantee for the users. Based on this, this paper presents a QoE-based multi-service resource allocation algorithm in LTE systems. Firstly, QoE is introduced to calculate user priority based on channel information, QoS requirements and fairness. In particular, a minimal QoE constraint is introduced to ensure QoE requirements of RT users. Secondly, a suboptimal resource block allocation algorithm is proposed to solve the complicated resource allocation optimization problem. The algorithm is divided into two steps： ensuring minimum QoE requirements for RT user; maximizing system weighting and rate. The simulation results show that compared with the existing RT/NRT resource allocation algorithm, the proposed algorithm improves the performance of user packet loss rate, average QoE and cell spectrum efficiency.
