LTE RACH/RRC Call Flow & PRACH Parameter Details, RA-RNTI, SIB2 | 4G E2E Signaling Session 2
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,
5G Massive MIMO Explained: Key 5G Enabler, Physical Layer Processing, SU-MIMO, MU-MIMO, and Beamforming (Article)
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
5G HARQ Explained: Soft Combining, HARQ Processes, ACK/NACK Timing, Codebook Types, Spatial Bundling, and 4G vs 5G Differences (Article)
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
