Self-clocked rate adaptation for conversational video in LTE

Abstract

This paper describes a rate adaptation framework for conversational video services. The solution conforms to the packet conservation principle and uses a hybrid loss and delay based congestion control algorithm. The framework is evaluated over both simulated bottleneck scenarios as well as in a LTE system simulator and is shown to achieve both low latency and high video throughput in these scenarios, something that improves the end user experience.
