Welcome to Session 2 of the 4G End-to-End Course. In this video, we break down the LTE Random Access Procedure (RACH) step by step and explain how the UE moves from downlink synchronization to uplink synchronization before starting the connection setup process. This session covers the complete RACH overall overview,

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

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/

Introduction PDCP is one of the most important layers in the 5G user-plane stack. It sits above RLC/MAC and directly impacts security, header size, packet ordering, and end-to-end latency. In this article, the focus is PDCP deep dive: the PDCP header, PDCP functions, key timers (especially discardTimer and t-Reordering)
