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
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
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.

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)

Mixed Reality

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.

3GPP Terminology:
Terrestrial Broadcast and Mixed Mode

LTE-Advanced Pro” May 2018

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

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
• 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
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

5G-Xcast Technical Solution Design in 3 phases
5G Multicast/Broadcast

24. 24
• 5G Broadcast solution in Rel-16 will be LTE-based – target completion date March 2020
– enTV Rel-14 with some small adjustments (e.g., numerology, CAS)
– Performance not comparable to state-of-the-art terrestrial broadcast standards (e.g. ATSC 3.0)
– But major handset vendors may be interested to integrate it into their 4G chipsets
• 5G-NR and 5G-Core will support only unicast in Rel-15 and Rel-16
• Good prospects for 5G Mixed Mode for Rel-17
– Common solution for all verticals: media, V2X, IoT, MCC, …
– SA2 SI for the 5G-Core on-going, WI in Rel-17 approved
– RAN still needs to decide topics for Rel-17 (latest Dec. 2018)
– NR Terrestrial Broadcast will not happen before Rel-18 at the earliest
• 5G-Xcast has designed a solid technical solution for 5G Mixed Mode and NR Terrestrial Broadcast, includingAir
includingAir Interface, RAN Architecture and Core Network
– It will be the reference point for the informative and normative work in 3GPP
– Approach followed in 5G-Xcast could be used in 3GPP as well
– 1º: generic PTM extension (Mixed Mode), 2º extension to terrestrial broadcast
