5G Course - all about LATENCY in 5G | RAN features | Scheduling | SINR

I start this video with definitions: What is latency? What is delay? What is Round Trip Time and ping time? What is Jitter and Time-to-Connect? Then I consider end-to-end latency budget in 5G network architecture, starting from UE capabilities, RAN latency features and end-user impact. I show how RAN features, TDD patters, scheduling and handovers could impact on overall latency. I also explain latency reasons in Transport, Core networks and VR/AR latency requirements. In addition, I propose methods on latency testing, including drive-tests, ping and TWAMP protocols. ⏰Time codes: 0:22 - Agenda 1:32 - Latency issue 2:15 - What is latency? 3:37 - What is Round Trip Time? 4:42 - Ping time = latency/RTT? 5:37 - Minimum RTT 6:37 - Latency jitter 7:45 - Latency and Time to Connect 8:27 - E2E Latency budget 10:38 - UE capability aspects 12:14 - Latency and SINR 13:20 - Latency and Numerology/SCS 15:26 - Freq bands for low latency 17:11 - FDD and TDD patterns for low latency 18:17 - 5G mini-slot for low latency 19:35 - 5G self-contained slot for low latency 20:45 - Scheduling impact on latency 20:02 - Grant-free scheduling and latency 23:07 - Scheduling optimization for low latency 25:43 - Scheduling impact examples 26:11 - UE mobility and 5G DAPS handover 28:15 - RAN latency during handovers 29:29 - DAPS Handover limitations 30:12 - RRC inactive state impact 31:02 - RAN features for improving latency 32:23 - 5G SA vs NSA latency 33:15 - Transport and Core latency 34:36 - Propagation delay in optic fiber and URLLC 36:24 - TCP/IP congestion delay 37:30 - X2/Xn overload 38:17 - Drive-Test latency testing 41:05 - Ping latency testing 43:00 - UE PHY/MAC latency testing 46:22 - TWAMP latency testing 50:03 - Latency impact on UE QoE 51:02 - Rohde&Schwarz QoE model 52:18 - Latency User Case requirements 54:23 - Latency - new vector for attracts! 🚀 Check my Udemy course on 5G NTN (Non-Terrestrial Networks): Total overview of Satellites integration into 5G networks: Click here👇(with Discount): https://www.udemy.com/course/5g-ntn-t... 🚀Check my Udemy course on 6G TRAINING: all about new 6G spectrum (FR3/FR4/FR5/FR6), JCAS/ICAS (6G sensing) and telecom trends and challenges Link:👇 👇 👇 (with Discount): https://www.udemy.com/course/6g-total...
