Recent advances in Broadcasting standards and research

  1. 1. Dr. Belkacem Mouhouche – Samsung Electronics Chief Standards Engineer Technical Manager of 5G projects: 5G-Xcast and 5G-Tours Recent advances in Broadcasting standards and research
  2. 2. 2 • 5G is a new way of thinking about connectivity. - Overview5G Data Rate 20 Gbit/s (user 100 Mbit/s) Mobility 500 km/h Latency 1 ms Connection density 106 devices / km2 Spectrum efficiency 3x – The 5G vision is driven by new use cases, vertical industries and business models that will emerge in the near future. – Media / Automotive / IoT / e-Health • Designed to meet very challenging technical requirements: 3G 4G 5G
  3. 3. Vision, Research and Standard 3 Standard Research Vision
  4. 4. Broadcast/Broadband differences Traditional Broadcast Broadband • Only supports TV • Optimised network for national coverage of popular content • Highly efficient use of spectrum for simultaneous delivery at edge of network • High barrier to provisioning a new service • Only support linear delivery • Supports many services • Non-optimised network for global coverage • Unicast at edge of network inefficient for simultaneous delivery • Very low barrier to provisioning a new service • Supports linear and on-demand
  5. 5. 5 Decreasing TV usage • The percentage of linear TV has decreased since the beginning of the decade. • The part of linear TV was almost 75% and is predicted to fall below 50% by the end of the decade.
  6. 6. 6 The need for broadcast • For example, a UK mobile network operator experienced a large increase in network traffic due to the England v. Wales Football football match during the afternoon, People watched on their phones. Increase in mobile network traffic during Euro 2016 football match (Source: BT/EE)
  7. 7. 7 • 5G is expected to provide new capabilities to satisfy user demands. – Over 78% of the world’s mobile data traffic will be video by 2021. • 5G will bring the means to deliver new immersive audio-visualmedia. The Role of Broadcast in 5G 4K/8K UHDTV content. High-Dynamic Range (HDR) High Frame Rate (HFR) Object-based content Virtual / Augmented / Mixed Reality 360° video
  8. 8. 8 • Innovative 5G use cases require broadcast transmissions! • Big potential in convergence of fixed and mobile broadband networks for large- scale media delivery. • Point to multipoint as a delivery optimization tool, rather than a service. • Broadcasters interest in 3GPP technologies has increased recently. – 4G LTE Rel-14 has incorporated many requirements, but suffers from the eMBMS legacy. The Role of Broadcast in 5G Broadcast allows an infinite number of users to receive the same content at the same time, using just a fixed number of resources.
  9. 9. 9 • Broadcast transmissions are key in many 5G use cases: Use Cases in 5G Broadcast CONNECTED CARS PUBLIC WARNING AND SAFETY Infotainment Safety Software Updates Common Control Messages Public Warning Systems Tsunami Alert MULTIMEDIA & ENTERTAINMENT UHDTV delivery VR and AR INTERNET OF THINGS

  13. 13. 13 3GPP Terminology: Terrestrial Broadcast and Mixed Mode Source: Qualcomm, “Accelerating the mobile ecosystem expansion in the 5G era with LTE-Advanced Pro” May 2018
  14. 14. 14 • Requirements for terrestrial broadcast in 5G are - for the first time - considered in Rel-14 – TR 22.816 3GPP enhancement for TV service (Dec. 2015) • Known issues: – Non-SFN signalling (CAS) – Poor spectral efficiency w.r.t. e.g. ATSC 3.0 – Max. CP: 200 µs – SCS: 1,25 kHz LTE enTV Rel-14 Source: R. Beutler, “5G for Broadcasters: A Reality Check” Nov.
  15. 15. 15 Terrestrial Broadcast and Mixed Mode in 3GPP Rel-16 at RAN#80 Terrestrial Broadcast: • Proposal to use LTE EnTV as a basis, going for an LTE-based 5G solution • Broadcast only, DL-only • Large & static transmission areas • Carry out a gap analysis to see if 5G requirements are fulfilled with Rel-14 EnTV • Enhancements (if any) needed to meet 5G requirements from TR 38.913, Clause 9.1 • Some modification needed in Rel-16 to have the 5G label! • Additional requirements from TS 22.261 if needed Mixed Mode Multicasting: • “Equivalent” of MBMS into NR • Switched broadcast/unicast • Potentially mixed DL & UL • Moderate & dynamically configured transmission areas • High commonality with unicast • Mixed mode multicasting should keep in mind use cases such as IoT and V2X Noted, might be considered for Rel-17 AcceptedRP-181342 RP-180669
  16. 16. 16 • Req.1 The new RAT shall support existing Multicast/Broadcast services (e.g. download, streaming, group communication, TV, etc.) and new services (e.g. V2X, etc). • Req. 2 The new RAT shall support dynamic adjustment of the Multicast/Broadcast area based on e.g. the user distribution or service requirements. • Req. 3 The new RAT shall support concurrent delivery of unicast and Multicast/Broadcast to the users. • Req. 4 shall support multiplexing with unicast transmissions in at least frequency domain and time domain. • Req. 5 The new RAT shall support static and dynamic resource allocation between Multicast/Broadcast and unicast; the new RAT shall in particular allow support of up to 100% of DL resources for Multicast/Broadcast (100% meaning a dedicated MBMS carrier). • Req. 6 The new RAT shall support Multicast/Broadcast network sharing between multiple participating MNOs, including the case of a dedicated MBMS network. • Req.7 The new RAT shall make it possible to cover large geographical areas up to the size of an entire country in SFN mode with network synchronization and shall allow cell radii of up to 100 km if required to facilitate that objective. It shall also support local, regional and national broadcast areas. • Req. 8 The new RAT shall support Multicast/Broadcast services for fixed, portable and mobile UEs. Mobility up to 250 km/h shall be supported. • Req. 9 The new RAT shall leverage usage of RAN equipment (hard- and software) including e.g. multi-antenna capabilities (e.g. MIMO) to improve Multicast/Broadcast capacity and reliability. • Req.10 The new RAT shall support Multicast/Broadcast services for mMTC devices. 5G Broadcast Requirement in 3GPP TR 38.913 Study on Scenarios and Requirements for Next Generation Access Technologies (Rel-14) approved in Oct. 2016
  17. 17. 17 Current Situation in 3GPP: Two Tracks • In March SA2 started a SI on “Architectural enhancements for 5G multicast-broadcast services” (TR 23.757) • There are good chances of NR-Mixed Mode being standardized in Rel-17 • NR-Terrestrial Broadcast will not happen before Rel-18 2017 Rel-14 Rel-15 FeMBMS 2018 2019 Rel-16LTE-based 5G Terrestrial Broadcast Rel-15 Rel-16 Only Unicast, no Broadcast yet / New Radio (NR)
