Abstract

The widespread adoption of 5G capable smartphones has made high-speed connectivity accessible to most users, with Enhanced Mobile Broadband (eMBB) technology playing a pivotal role in delivering faster download and upload rates. The diverse range of services enabled by 5G networks demands innovative solutions for optimizing resource allocation and enhancing overall network performance. To address these challenges, 5G New Radio (NR) introduces several critical features, including flexible Time Division Duplexing (TDD), which dynamically allocates time slots based on traffic demand to maximize spectral efficiency and adaptability under varying network conditions. This paper investigates the impact of different TDD band configurations on throughput performance, specifically focusing on downlink traffic in 5G networks.
