Abstract :
Performance comparison of control-less scheduling policies for VoIP in LTE UL is conducted in this work. In LTE system, the main challenges of effectively supporting VoIP service are the control channel restriction from the large number of simultaneous users and the frequent arrival of small packets. Semi-persistent scheduling and group scheduling are the main methods to solve above problem and achieve QoS requirements. By simulation, we prove that semi-persistent scheduling outperforms group scheduling in the case of no group interaction for group scheduling.
