Broadcast 5G Convergence New Ideas

  1. 1. 1 © 2018 ONE Media 3.0 LLC. All rights reserved. Open Discussion Broadcast 5G Convergence Release 16 New ideas ATSC 3.0 (L1 layer) extensions (ATSC 3.0 Tools) broadcast Convergence 5G Note: These New Ideas are outside scope of ATSC (SDO) No support should be assumed https://www.atsc.org/standards/atsc-3-0-standards/
  2. 2. 2 © 2018 ONE Media 3.0 LLC. All rights reserved. Motivations New Ideas Broadcast 5G Convergence • New Flexibility ATSC 3.0 L1 (A/321, A/322) by extending baseline • New Extended OFDM Numerology, L1 Signaling, Frame Structure • Improve Broadcast Mobility, Larger BW and Higher Frequency band Options • Broadcast Convergence 5G Release 16 (Core Network Layers and UE) • Emergence of Broadcast SDR Chip (Multi-RAT) • Saankhya/ ONE Media 3.0 SDR Chip (1st shown CES 2019) • A/321 Bootstrap Multi (Root + Seed) capability Multi-RAT support • 3GPP Release 16 is right time with new 5G Core Network Paradigm • New 5G Core Service Based Architecture (SBA) Agnostic to Access Network • Supports Non-3GPP Access Networks and Dual Conn UE (See TR 23.793) • Broadcast (L1) extended is positioned as a Non-3GPP Access Network
  3. 3. 3 © 2018 ONE Media 3.0 LLC. All rights reserved. 5G Core Network Release 16 Two Types of Non-3GPP Access Networks 1. Trusted Non-3GPP Access (Broadcast) tightly integrated into 5G Core (MNO benefits without any support broadcaster) MNO has spectrum 2. Un-Trusted Non-3GPP Access (Broadcast) Broadcaster + MNO cooperative convergence Spectrum Co. Model USA Will call out when each Non-3GPP access method is discussed 5G Core (SBA) is Agnostic to access network Icon used to indicate new or important concepts
