5G NR Throughput Calculator
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

5G NR MAC DL/UL Scheduling Algorithms
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
