5G Beam Selection Made Simple: CSI-RS, PMI & UE Capability Explained

Mohamed ELAdawi

28 Jul 2025

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 for engineers seeking a practical understanding of CSI-based beam management.

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

5G PDCP Deep Dive: Split Bearers & Retransmission Explained

In this video, we explore two essential 5G PDCP functions: * Split bearers and routing in EN-DC setups. * PDCP-layer retransmission.

5G PDCP Reordering & In-Order Delivery Made Simple
