5G NR SA Signalling
Course Contents
This course constitutes a genuine training paradigm in the global telecommunication infrastructure for 5G Stand Alone (SA) signaling procedures. Audience will follow a full SA signaling analysis associated with log files extracts and examples in the overall RRC Idle, RRC connected mode, mobility and Accessibility analysis together with optimization procedures.
Target Audience
Technical professionals, RAN planning engineers, RAN optimization engineers, who need a better understanding in 5G NR SA optimization or troubleshooting procedures.
Course Outcomes
• Explain in full details the L3 (RRC) signalling and L2 (MAC) signalling
• Explore the 5G NR SA signalling flows
• Practical approach using SA log files with emphasis to radio parameters and optimization
