In this video, we simplify how 5G gNB selects the optimal beam for each UE using CSI feedback. We walk through the complete flow — from CSI-RS measurement and UE feedback (PMI, CQI, RI) to beamforming implementation — and explain key RRC configurations and UE capability checks from the 3GPP standards. good

This video covers a high-level view about 5G Beamforming types: * Eigen-Based Beamforming (EBB): Dynamically updates beamforming weights to track UE movement. Suitable for TDD, leveraging channel reciprocity and SRS-based uplink measurements to derive downlink weights. Requires high baseband processing to track UEs in real-time. * Grid of Beams (GoB): Uses a

This video explains the 5G beamforming life cycle in a simple way. * It starts with how the UE finds beams in idle mode, then how it connects and refines those beams. * You’ll also see how data is transmitted using beamformed signals, and how the network handles mobility and beam

This video explains PDCP reordering, the role of T-reordering timers, and how it all impacts user experience and latency — with clear visuals and a practical touch.

In this video, we break down two key 5G PDCP functions: the Discard Timer and ROHC (Robust Header Compression). Learn how they work, why they matter, and how they impact performance — all in a clear and practical way.
