Abstract

The ever-evolving landscape of wireless communication technologies has led to the development of 5G-NR (5G New Radio) networks [1] promising higher data rates and lower latency. However, with these advancements come challenges in managing intra-cell and inter-cell interference, particularly during the random-access procedure. This article aims to explore the impact of UE (User Equipment) and cell configuration parameters on interference and establish improved interference management strategies. To assess the effectiveness of these strategies, Key Performance Indicators (KPIs) such as Correct Detection Rate (CDR) will be considered. Additionally, the Matched Filtering (MF)-Based PRACH (Physical Random-Access CHannel) detection algorithm [2] will be studied to evaluate the PRACH performance. The findings underscore the critical role of interference management and the configuration of User Equipment (UE)/Cell parameters in ensuring the robustness and reliability of the NR-PRACH performance in 5G NR networks. Optimizing these configurations can lead to improved network performance and enhanced communication quality.
