Abstract
In this paper, performance of VoIP service on LTE UL system is studied and analyzed via semi-static system level simulations. Simulations show that different scheduling schemes have a big influence on the UL VoIP capacity - semi-persistent method is quite promising due to its ability to decrease DL signaling overhead and a good performance that is comparable to more advanced methods. The impacts of different VoIP packet sizes, different usage scenarios and different scheduling mechanism are analyzed as well. Those are concluded from the simulation results.
