Analysis of Uplink Scheduling for Haptic Communications

TL;DR

This paper investigates uplink scheduling in 5G networks for haptic communications, analyzing how different access procedures affect latency, resource efficiency, and the performance of other traffic types using stochastic network calculus.

Contribution

It models the impact of uplink access procedures on haptic and other traffic, providing insights into optimizing tradeoffs between speed and resource efficiency.

Findings

Optimal tradeoff points depend on haptic data rate.

Faster access improves latency for haptic traffic.

Resource-efficient access benefits overall network performance.

Abstract

While new mechanisms and configurations of the 5G radio are offering step forward in delivery of ultra-reliable low latency communication services in general, and haptic communications in particular, they could inversely impact the remainder of traffic services. In this paper, we investigate the uplink access procedure, how different advances in this procedure enhance delivery of haptic communication, and how it affects the remainder of traffic services in the network. We model this impact as the remainder of service, using stochastic network calculus. Our results show how best the tradeoff between faster or more resource efficient uplink access can be made depending on the rate of haptic data, which is directly relevant to the application domain of haptic communication.
