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
Hi All, Session 1 of the 4G E2E Signaling Course is now available on YouTube. In this session, we build the essential LTE foundation concepts needed before going into detailed end-to-end signaling procedures such as attach, bearer setup, handover, and service request. This video explains how the UE in LTE/
