5G RLC Development Mastery using C++ | TS 38.322 Protocol Implementation & Debugging

Are you looking to transition from 5G Testing to 5G Development roles? Do you want to understand how the Radio Link Control (RLC) layer is actually implemented inside commercial 5G products?
This production-oriented course is designed to provide a deep understanding of 5G RLC protocol development, aligned with 3GPP TS 38.322, through extensive C++ coding, debugging, protocol analysis, and hands-on lab exercises.
Unlike theory-focused telecom courses, this program emphasizes real-world implementation concepts, enabling participants to understand how RLC entities are developed, debugged, tested, and validated in telecom products used by leading vendors such as Nokia, Ericsson, Samsung, ZTE, and Mavenir.
Participants will learn the complete behavior of TM (Transparent Mode), UM (Unacknowledged Mode), and AM (Acknowledged Mode) RLC entities, including segmentation, reassembly, retransmission, polling, status reporting, buffer management, timers, and state-machine implementation.
The course follows a debugger-based learning approach, where every major concept is reinforced through C++ implementation and GDB-based debugging sessions, helping participants visualize protocol behavior step-by-step.
Additionally, learners will gain exposure to Amarisoft log analysis, enabling them to correlate protocol specifications with real network traces and troubleshooting scenarios.
