System Level Performance Evaluation of LTE-V2X Network

Abstract

Vehicles are among the fastest growing type of connected devices. Therefore, there is a need for Vehicle-to-Everything (V2X) communication i.e. passing of information from a Vehicle-to-Vehicle (V2V) or Vehicle-to-Infrastructure (V2I) and vice versa. In this paper, the main focus is on the communication between vehicles and road side units (RSUs) commonly referred to as V2I communication in a multi-lane freeway scenario. Moreover, we analyze network related bottlenecks such as the maximum number of vehicles that can be supported when coverage is provided by the Long Term Evolution Advanced (LTE-A) network. The performance evaluation is assessed through extensive system-level simulations. Results show that new resource allocation and interference mitigation techniques are needed in order to achieve the required high reliability requirements, especially when network load is high.

A novel alternative to cloud RAN for throughput densification: Coded pilots and fast user-packet scheduling at remote radio heads

“…5G technologies are expected to bring great performance gains with respect to their predecessors in a multitude of performance metrics, including, among other things, user and cell throughput, end-to-end latency, massive device connectivity and localization. They are also viewed as essential elements for enabling the much broader gamut of services envisioned, such as immersive applications (e.g., virtual/augmented/mixed reality) [4], [5], haptics [6], V2X [7] and the Internet of Things [8]. To meet such an ambitious and broad gamut of 5G requirements, operators would have to rely on a combination of additional resources, which include newly available licensed and unlicensed bands, network densification, large antenna arrays and new PHY/network layer technologies.…”
