• 5G is a new way of thinking about connectivity.– The 5G vision is driven by new use cases,
vertical industries and business models that will emerge in the near future.
– Media / Automotive / IoT
• Designed to meet very challenging technical requirements:

• 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-visual media.
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

• Suitable to deliver the same content to an unlimited number of users/devices within the covered area, with a defined and stable quality of service
– Without substantially increasing network capacity requirements, energy consumption, costs
• Can offer huge capacity gains and sustainable operation of services, ensuring a cost effective high quality delivery mechanism
– This also allows valuable network resources to be reused for unicast-only applications
The Role of Broadcast in 5G
8
• Innovative 5G-TV 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.– enTV 4G 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
• As part of the Rel-16 framework, 3GPP has started the normative work to further develop LTE-based 5G Terrestrial Broadcast.
Study Item
• To perform a gap analysis and compare the capabilities of eMBMS Rel-14 against 5G requirements 5G.
• Main enhancements identified:i. To support integration of HPHT (high-power high-tower) broadcast infrastructures for large SFN coverage.
ii. To enable high speed reception from medium-scale SFN areas.
Work Item
• Solutions to meet the identified gaps:– To specify new numerologies and signaling for fixed and mobile reception in MPMT and HPHT
environments
– Enhance (if required) physical channels and signals.
The Role of Broadcast in 5G
10
• Hybrid broadcast service:– Users have access to linear or non-linear audio-visual material.
– Content available as they move between different locations or environments in a seamless manner.
– Transmissions over:
– TV station
– 5G Cellular network
– Wi-Fi
Use Cases in 5G TV
11
• VR/AR Broadcast:– Virtual and augmented
reality content sent to many users at once.
Use Cases in 5G TV
• Remote live production:– Professional content is produced
remotely in specific events.
– Reduced cost and more flexibility.

Point-to-multipoint capabilities
– First project to work on 5G multicast/broadcast.
– Reference work for 3GPP Release-17
Adaptable and converged network architecture
– One solution for all verticals, including terrestrial broadcast, to hide multicast/broadcast delivery from the users and make it an internal optimization tool.
Innovative use cases demonstration
– Demonstrations EUCNC 2018, IBC, MWC, EUCNC 2019
– Field trials in three test-beds: IRT, TUAS, 5GIC
– Showcase at the European Championships
Main Objectives

• Broadcast is key in many 5G use cases, but they were not considered in the first phase of 5G (Rel’15-Rel’16)
• The project did not only considered TV and multimedia, but also:
Motivation: lack of broadcast in Rel-15

– The touristic city (Turin, IT): set of use cases for improving the touristic experience at a city with media applications.
– The safe city (Rennes, FR): eHealth use cases that ensure travelers and citizens that, even in case of trouble, they will recover thanks to management of an emergency situation.
– The mobility efficient (Athens, GR): the use cases depict how airport processes can be improved leveraging 5G both from the side of the visitors and of the airport management.

• Mixed unicast/broadcast services in cellular networks– MNO-Centric: The content is transmitted via the cellular 5G network in a mixed mode where
multicast/broadcast and unicast share resources
– Part of the content needs to be personalized. Some information is delivered by the user in the uplink.
• 5G Broadcast delivery to massive audiences– Broadcast-Centric: Receive-only content to all users at once, using High-Power High-Tower (HPHT)
broadcaster’s infrastructure.
