Session #6 of our FREE 4G/LTE Fundamentals & End-to-End Signaling training is now available on YouTube! "English Speaker" In this session, we continue with Part 2 of the 4G LTE Attach Procedure, focusing on: * End-to-end signaling flow * Detailed explanation of signaling messages and
5G NR SSB Deep Dive: Cell Search, Beam Sweeping, Power & Optimization | بالعربي
في الحلقة دي من سلسلة 5G بالعربي، هنبدأ Deep Dive عملي ومفصل في 5G NR Synchronization Signal Block (SSB)، من الـ fundamentals لحد الـ practical impact على coverage, accessibility, beam management and optimization. هنبدأ الأول بفهم الفرق بين 4G and 5G Synchronization Signals، وإزاي طريقة إرسال الـ synchronization signals اتغيرت
LTE Attach Procedure | E2E Call Flow, MME, EPS Bearer & Default Bearer | 4G E2E Signaling Session 5
Session 5 of my 4G/LTE E2E Signaling series is out: the LTE Attach Procedure. Attach is the first thing a phone does on an LTE network. It registers, gets authenticated, receives an IP address and sets up the Default EPS Bearer. In this session: → Attach Functions & Triggering Conditions
RACH CBRA/CFRA Call Flow and Use Cases
Overview The Random Access procedure can be initiated in different situations depending on whether the network already knows the UE and whether dedicated resources can be assigned. Random Access Channel, or RACH, is used whenever the UE needs to establish or recover uplink synchronization with the network. In 5G, Random
4G LTE Cell Selection Explained: Initial Selection, Stored Information and Cell Selection Criteria
Introduction After the UE completes system information acquisition, the next step is to determine whether the detected cell is suitable for camping. This process is called cell selection. During cell selection, the UE checks the available LTE cells and evaluates whether a cell satisfies the required coverage, quality, and access
5G PDCCH Optimization Approach: Understand DCI Applications, CSS vs USS and What Is Consuming PDCCH Resources
Introduction When PDCCH utilization becomes high, the first question should not immediately be: Which PDCCH optimization feature should I enable? A better starting point is to understand what the PDCCH resources are actually being used for. PDCCH is involved in different procedures such as SIB1 transmission, Other System Information, Random
5G NSA SgNB Addition: Key Timers Impacting the Success Rate
During SgNB Addition, there are three important timers that can directly affect the SgNB Addition Success Rate. The figure below shows where each timer starts and stops within the call flow. SgNB Addition Call Flow and Related Timers After the B1 Measurement Report is received, the MeNB starts the SgNB

* My 5G RAN Performance & Optimization course is now officially published on Udemy! After a long journey of recording, reviewing, restructuring, and creating the material, I’m very happy to finally share it. * The course includes 35+ hours divided into 333 lectures of training covering both 5G SA and NSA,
SRS-Based Beamforming in 5G | PDSCH & PDCCH, Antenna Switching, SRS Gain Explained (Article)
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
LTE RRC States Explained | ECM, EMM & 4G to 5G Transitions | 4G E2E Signaling Session 4 (Video)
In this Session 4 of the 4G End-to-End Signaling Course, we break down LTE RRC states, RRC Idle vs RRC Connected, LTE to 5G state transitions, and the role of ECM and EMM states in the EPC/core network. You will learn how the UE is viewed from
LTE Network Architecture Deep Dive | RAN, EPC, Interfaces & Cloud EPC | 4G E2E Signaling Session 3 (Video)
Welcome back to the 4G End-to-End Signaling Free Course – Session 3. In this session, we build the foundation for understanding LTE signaling by explaining the 4G LTE architecture, the role of each major EPC node, and how different network elements communicate with each other. You will learn the
