Introduction SRS-based beamforming is one of the most important topics to understand after learning the basics of 5G beamforming, SSB, CSI-RS, and codebook-based operation. In practical terms, this topic explains how the gNB can use uplink SRS sounding to estimate the downlink propagation channel and then generate

Introduction Downlink beam management is one of the most important parts of 5G Massive MIMO. It is the process used by the network to identify, refine, and maintain the best beam direction for each UE, starting from initial access and continuing during connected mode. Unlike 4G, where beamforming was mainly

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

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
