5G Beam Selection Made Simple: CSI-RS, PMI & UE Capability Explained
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
5G Beamforming Types- Eigen based Vs Grid of beams
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
Beamforming Life Cycle in 5G – Made Simple
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
