Overview: A 3GPP-aligned, multi-layer throughput estimation tool covering the full gNB protocol stack from PHY to PDCP. Built for RF engineers, protocol testers, and RAN architects who need quick but specification-accurate numbers without opening a spreadsheet or reading 38.214 line by line. Tool Features 4-layer protocol stack Calculates throughput independently at PHY, MAC, RLC, and PDCP — each with its own overhead model per 3GPP specs, not a single flat deduction. All thr

1. Introduction Power control is one of the least visible but most influential mechanisms in cellular radio systems. In 5G NR, it directly impacts: Uplink throughput and latency Cell-edge user experience Inter-cell interference UE battery life Massive MIMO beam efficiency Network energy consumption (Green RAN goals) Unlike LTE, 5G NR operates with: Very wide bandwidths Beam-based transmission Dynamic TDD Cloud-native and O-RAN architectures As a result, power control in 5G NR

1. Introduction: Why RLC Still Matters in 5G NR When discussions around 5G performance arise, attention usually gravitates toward massive MIMO, beamforming, or spectrum efficiency. Yet, in real networks, user experience often degrades due to issues far removed from PHY or antennas. One of the most common root causes lies in the Radio Link Control (RLC) layer. In 5G NR, RLC sits between PDCP and MAC, just like LTE. But assuming it is “unchanged from LTE” is a mistake. While t

1. Introduction Medium Access Control (MAC) scheduling is one of the most critical real-time functions in a 5G NR gNB. It directly determines throughput, latency, fairness, spectral efficiency, and QoS compliance. Unlike LTE, 5G MAC scheduling operates in a much more complex design space due to: Flexible numerology (multiple SCS) Mini-slots and slot aggregation Beam-based transmissions Massive MIMO QoS flows (5QI-driven scheduling) URLLC pre-emption and puncturing Dynamic TDD
