In this paper we examine the feasibility of semi-persistent scheduling (SPS) for voice over IP
(VoIP) by random access and evaluate its performance in terms of throughput of random …

This paper presents an effective scheduling scheme called semi-persistent scheduling for
VoIP service in LTE system. The main challenges of effectively supporting VoIP service in …

One of the major limitations of the LTE system in context of Machine-to-Machine (M2M)
communications is the excessive control signalling required for dynamic scheduling of radio …

Since 3GPP has introduced sensing-based semi-persistent scheduling (SPS) into the MAC
layer of LTE-V2X Mode 4 in release 14, various studies have been carried out to evaluate its …

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 …

This paper presents a novel modulation and coding scheme (MCS) selection method to
optimize the performance of Voice over Internet Protocol (VoIP) semi-persistent scheduling …

Nowadays, Voice of LTE (VoLTE) is used to support voice communications in LTE network.
As one of the key techniques for VoLTE, semi-persistent scheduling (SPS) is important to …

Large number of M2M devices are anticipated to be operating in future LTE networks which
impose several system design challenges and wide range of service requirements. The LTE …

A fully packet switched access network such as 3G LTE imposes new challenges for real
time voice services. Packet drop, delay variation, and random channel fading calls for …

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 …
