Abstract

In this paper, different algorithms related to 5G throughput and latency procedures for Non-Standalone (NSA) and Standalone (SA) modes are developed. The 5G throughput and latency are improved by reducing the bad radio link quality and by optimizing the 5G parameters configuration of the frame structure, which decides how many slots and symbols are available for data transmissions and how many slots are used for signaling overhead. This will require an improvement of signal interference noise ratio (SINR), Bloc Error Rate (BLER), modulation coding scheme (MCS), and choosing the best setting for the new radio (NR) frame structure. To achieve the target of ultra-low latency, we also need to decrease the congestion of the network by optimizing the Quality of Service- based scheduling and network slicing features. The objective is to improve both key performance indicators (KPIs), throughput, and latency, and reach the target KPIs by tuning the main 5G radio parameters for NSA and SA networks.

Highlights

  • Illustrate the main factors that are impacting 5G throughput and latency

  • Classification of 5G main parameters that influence 5G throughput and latency

  • Present an optimization algorithm which checks all procedures related to throughput and latency

  • Evaluation of the impact of 5G frame structure parameters configuration on throughput and latency

  • A tradeoff exists between 5G throughput and latency optimization
