I'll be going to this tonight and will report back. I know a lot of us are
interested in this sort of thing. We are going to be ramping up very
quickly into some QoS issues with GSE and queuing. I'll be asking any
questions I can about that during the Q&A.

I put the fred harris slides and audio recording in our papers and
presentations repo (from night before last). It was excellent (as
expected).

If you have any questions (no matter how snarky) for the speaker below,
just let me know and I will stand up and straight-face ask them.

More soon!

Non-Orthogonal-Multiplexing: An Enabling Technology for Next Generation
Broadcast and Broadband Multimedia Communications


December 6, 2018, Thursday

Program:

Non-orthogonal multiplexing (NOM) technology can provide significantly
higher transmission capacity than the traditional orthogonal multiplexing
(OM) technologies, when delivering multiple services with different quality
of service (QoS) requirements. This has been recognized by research
communities from both the broadcast industry and the mobile broadband
industry.

The NOM technology can find many applications in future broadcast and
broadband systems, including the simultaneous delivery of mobile and fixed
services, seamless local content insertion, and delivery of mixed
unicast-broadcast services in 4G/5G systems. A particular interesting new
application scenario of NOM is recently developed to realize more efficient
integrated broadcast service and backhaul (ISB) transmission, in both next
generation ATSC 3.0 digital broadcast system and for 5G broadcasting
system. This concept is directly related to the integrated access and
backhaul (IAB) technology currently being studied for 5G NR.

This talk starts with the fundamental capacity benefit of NOM technology
over OM technologies from the information theory point of view. Then, the
different applications of NOM technology in future broadcast and broadband
systems are introduced, including the benefit that NOM offers and the
challenges to realize it in practice. General guidelines for achieving
feasible implementation of NOM in practical systems are subsequently
presented that keeps a low complexity and still achieve most of the NOM
benefits.

As the second part of this lecture, the concept of using NOM to implement
integrated service and backhaul links is introduced. First, the application
of this concept in the next generation ATSC 3.0 is presented focusing on
supporting low-power gap-fillers to improve the mobile service coverage
performance for highly populated indoor and closed areas (airports,
shopping malls, stadiums, etc.). Next, this concept is extended for
integrated access and backhaul in 5G framework, where the focus is put on
realizing a low-cost MBSFN over the low-power-low-tower broadband networks.
