Abstract

This paper studies the performance of Voice-over-Internet-Protocol (VoIP) service in the third generation (3G) long-term evolution (LTE)-Advanced relaying networks. We propose a semi-persistent scheduling algorithm for the VoIP service in the LTE-Advanced relaying networks. The performance of the presented algorithm is verified by system-level simulation. Deployments with different number of relay nodes are taken into account in the simulations. The results show that through deploying relays, the packet delay of cell edge users can be dramatically decreased. Moreover, the VoIP capacity of the relaying networks can also be increased obviously.
