Uplink Power Control Optimization for XR and eMBB Co-Existence in 5G-Advanced Networks

Abstract

This paper presents an analysis of fifth-generation (5G)-Advanced uplink system-level performance with the coexistence of extended reality (XR) and enhanced mobile broadband (eMBB) traffic. Dense urban (DU) and indoor hotspot (InH) deployments are studied. The study investigates the influence of uplink power control (UPC) parameters on the XR capacity and proposes strategies to manage eMBB inter-cell interference through traffic-specific UPC settings. By jointly optimizing UPC parameters for each traffic type, this research aims to minimize the eMBB throughput degradation while safeguarding the XR capacity. The findings reveal the impact of deployment scenarios on XR and eMBB capacity, and the trade-offs involved in the UPC optimization. These findings offer valuable guidance to cellular operators for optimizing network configurations to accommodate emerging XR traffic alongside existing services.
