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,
