QoS and Terminal Power-Aware Resource Allocation for Real-Time Traffic in e-MBMS System

This paper studies the issue of resource allocation of real-time traffic based on Quality of Service (QoS) and terminal power consumption in enhanced Multimedia Broadcast/Multicast Service (e-MBMS) system, and a two-layer QoS and terminal power-aware resource allocation scheme is also proposed. Aiming to minimize the number of received sub-frames for users, it takes the queue delay and fairness of multicast sessions into account, so that the QoS requirements of real-time traffic are satisfied. Simulation results show that the proposed scheme decreases the terminal power consumption efficiently and improves the system throughput, while maintaining the fairness among the multicast sessions. In the case of the same QoS constraints, it obtains the power gain by nearly 10% compared with the conventional schemes.
