This video covers Session 4 of the E2E VoLTE Training Campaign. In this session, you will go through the following:
- E2E VoLTE signaling procedures for the Mobile Terminated (MT) call flow
- 4G Paging
- An explanation of what the ECM states mean
Note: Material Sources will be added at the end of the full training
Introduction In the first Massive MIMO article, we focused on the antenna foundation: passive vs active antenna, antenna structure, antenna elements, and the basic MIMO concepts behind beamforming. First Article: 5G Massive MIMO Fundamentals: Passive vs Active Antenna, MIMO Gains, and Antenna Specifications and Structure This second part moves one
Introduction * HARQ is one of the most important reliability mechanisms in the 5G MAC layer. It directly affects retransmission speed, uplink control overhead, latency, and overall scheduling efficiency. * In simple words, HARQ gives 5G a fast retransmission loop. It helps recover transmission errors much faster than higher-layer recovery, which is
Introduction The Synchronization Signal Block, or SSB, is one of the first NR signals a UE must detect before it can access a 5G cell. It is the entry point for synchronization, cell identification, essential broadcast information, and beam-based initial access. If the UE cannot find and decode SSB correctly,
Introduction 5G Massive MIMO is one of the most important topics to understand before going deeper into NR beamforming, beam management, CSI-RS, SRS, layers, ports, and MU-MIMO. This article explains why Massive MIMO is different from traditional MIMO, how the antenna structure changes, where the main gains come from, and
