5G Beamforming Types- Eigen based Vs Grid of beams

24 Jul 2025

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 fixed set of beam positions, switching between predefined beams based on UE feedback. Suitable for both FDD and TDD, requiring less baseband processing than EBB.

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

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

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.
