5G Call Flows (Session 1): How a 5G UE performs Initial Access 5G Call Flows (Session 1): How a 5G UE performs Initial Access
One of the most complex area for beginners is to understand 5G Call Flows and Signaling procedures. 3GPP defines them but they are not easy to understand. So this video explains the 5G Call Flows in a simplified manner and also includes the contents of some of the important messages to show what actually goes on between UE/Mobile and the 5G network during the 5G Initial Access or Network Entry procedure! -

5G Massive MIMO is one of the most sought after topic and it is also one of the most complex and confusing topic as well. However, in this 30 minute session, Massive MIMO is demystified and anyone who goes through this session should be able to understand this topic clearly! -
LTE KPI Optimization (Session 1): ERAB Setup Success Rate LTE KPI Optimization (Session 1): ERAB Setup Success Rate
This video is the first session in LTE KPI Optimization list and explains the LTE ERAB Setup Success Rate KPI. The session covers the signaling flow for LTE accessibility in detail along with messages where the KPIs are pegged. The causes of LTE ERAB Setup failures are also covered in detail along with actions that can resolve those issues. -
5G Call Flows (Session 2): 5G Intra-gNB & Inter-gNB Mobility Overview 5G Call Flows (Session 2): 5G Intra-gNB & Inter-gNB Mobility Overview
5G Call Flows (Session 2): The 5G Mobility Overview explains the 5G call flows for Intra-gNB and Inter-gNB handovers (PSCell Change) based on 3GPP 37.340 & 36.423. -
5G Uplink Channels: Learn About UL Channels With UE Logs! 5G Uplink Channels: Learn About UL Channels With UE Logs!
The video covers the 5G Uplink Channels and their functionalities. It also adds a new dimension by adding UE logs and signaling level explanation for uplink channels and their configuration explaining how the mobiles find out about the uplink channels in order to access them. -
LTE SINR vs 5G SINR: Why Do We Have Different Types Of SINRs In 5G? LTE SINR vs 5G SINR: Why Do We Have Different Types Of SINRs In 5G?
In 5G, we have SS SINR, CSI-RS SINR and then there is PDSCH SINR while in LTE, we just have a single SINR that is usually used for all purposes. So, this session explains why we need multiple SINRs in 5G and what is the functionality of each of these SINRs. -
5G Frame Structure: Learn to Navigate the 5G Frame and Channels 5G Frame Structure: Learn to Navigate the 5G Frame and Channels
This explains all the 5G NR Physical Channels along with their basic functions. This is important to understand because these channels serve as a main building block in understanding all the other 5G topics. -

5G Throughput Optimization Basics #1 - Data Scheduling & Link Adaptation 5G Throughput Optimization Basics #1 - Data Scheduling & Link Adaptation
This video explains the basics of 5G Data Scheduling and Link Adaptation. It starts from the interaction of CQI and MCS as both of them are required for data scheduling. It further explains how CQI is used to estimate MCS and throughput and what are the factors affecting each of them. In the end, it touches the BLER control algorithm with details about BLER Target and its implications on the scheduling algorithms.
