In December 2017, 3GPP officially released its first set of Release 15 specifications describing the physical layer for the 5G New Radio (NR) technology. Final specifications on the 5G NR protocol stack are still ongoing and will be completed by March 2018 with Abstract Syntax Notification One (ASN.1). Further corrections and clarifications in the physical layer specifications can be expected during this timeframe as 3GPP members start implementation and discover potential areas of improvement. Initial 5G NR deployments will focus on a non-standalone (NSA) mode. In the next step, 3GPP will specify a standalone (SA) mode by mid-2018. This webinar provides an overview of the latest 5G NR physical layer specification, discusses the test challenges related to 5G and demonstrates practical test solutions. The webinar concludes with a look at the challenges involved in SA operation.
Attendees will learn:
• 5G NR physical layer details
• How to test the 5G NR physical layer
• Challenges of the 5G NR standalone (SA) mode

The long CP (cyclic prefix) topic seems off the mark. The video presentation describes that 1st symbol of every 1ms subframe has a longer CP. Instead, the first symbol of every .5ms has a longer CP. In other words, every 1ms subframe has 2 symbols with longer CP. For 15Khz LTE like case, we got every 7th symbol in the frame with long CP.

How did you consider, 3.5Ghz as frequency band, in actual deployments how is a certain band selected for UE? Is it a brute force?

How is SS-RSRP measured? Is it measured by scanning SSS in SS-PBCH block or DMRS? I am confused over DMRS and SS-RSRP, are they linked for measurement?

How can I get the slides for this presentation?

What about k-ssb? It is required to find the SSB position right?

symbol length (66.67us and 16.67us) is not including the cyclic prefix, isn't it?

Dear Manish, yes, that's correct!

Actually our experts just finished the book 5G New Radio - Fundamentals, procedures, testing aspects. The printed version is available with the ISBN 978-3-939837-15-2. Or you can pre-register for our e-book: www.rohde-schwarz.com/solutions/test-and-measurement/wireless-communication/wireless-5g-and-cellular/5g-test-and-measurement/5g-nr-ebook_250786.html
