• 5G is the next-generation of cellular networks (after 3G and 4G) • It will not only provide one order of magnitude increase in peak data

rates• It is being designed to meet very challenging technical requirements

to support new use cases derived from several vertical industries, not just for mobile broadband

• MNO-centric approach– Unicast (PTP)– Multicast/broadcast (PTM) as internal delivery optimisation tool, dynamic

switching between unicast and multicast (MooD)• Broadcast-centric approach: Terrestrial Broadcast

– DL-only, Free-to-Air, SFNs, HPHT, ….

Distribution of TV Content in 3GPP

32

• Requirements for terrestrial broadcast in 3GPP 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

3GPP Rel-16 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

Point-to-Multipoint (PTM) transmissions are key in many 5G use cases, but they have not been considered in the first release of 5G (Rel’15)

Motivation: Lack of 5G PTM in Rel-15

Convergence Vision

The converged media delivery architecture of 5G-Xcast over fixed broadband, mobile broadband and terrestrial broadcast networks allows a seamless, uninterrupted service to be offered to the users as they move.

45

Point-to-multipoint capabilities– To develop broadcast and multicast capabilities for the standalone 5G New Radio and

5G Core Network.

Adaptable and converged network architecture– Design a 5G converged network architecture combining fixed, mobile and terrestrial

networks to dynamically and seamlessly switch between unicast, multicast and broadcast modes or use them in parallel.

Innovative use cases demonstration– Develop proof-of-concept prototypes at Radio Access Network (RAN), core and content

distribution level and experimentally demonstrate key innovations developed in the project for the media and public warning verticals

Main Objectives

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

tourists, making cities more attractive to visit, more efficient in terms of mobility and safer for everybody.• Approach: Design and deployment of an architecture composed of the pre-commercial components brought

by the 5G-EVE platform along with the innovations coming from Phase 2 projects and 5G-TOURS. Implementthe 5G-TOURS solutions combining the use of the network slicing instances of the architecture and thevertical solutions relying on 5G communication that is needed for the use cases.

• Overview: This use case targets the distribution of enhanced high-quality video services for tourists, citizens and students providing immersive functionalities to enrich their touristic and/or educational experiences.

• Objective: distribution of audio-visual (A/V) content and services to a potentially unlimited number of users. The A/V content can be either 4K object-based broadcast videos for smartphones and TVs or immersive media for AR/VR devices.

Use Case: High quality video services distribution

Metric Required valueLatency ≤ 10 ms (A/R services)

Reliability 99.9999%Mobility 250 Km/h

Coverage Turin city (radio ~15 km)Data rate per user/device ≥ 25 Mbps

ICT-19-2019 | Grant Agreement No. 856950

1. Mixed unicast/broadcast services in cellular networks– The content is transmitted via the cellular 5G network in a mixed mode where

multicast/broadcast and unicast share resources – It allows to distribute immersive contents to a large number of users, where part of the

content needs to be personalized and there is also information being delivered by the user in the uplink.

– The trials will be divided in several stages of implementation and demonstration:1. 5G NSA with eMBMS capabilities. 2. Unicast/multicast switching Mood between 5G NR and eMBMS.3. Potential implementation of 5G SA with eMBMS capabilities, like the theoretical 5G-Xcast approach

Use Case: High quality video services distribution

2. 5G Broadcast delivery to massive audiences– To transmit the content to all users at once as a broadcast-centric receive-only approach

using High-Power High-Tower (HPHT) broadcaster’s infrastructure.– The trials will be divided into two stages:

1. FeMBMS Rel-14 also called enTV and 5G Broadcast with Aosta Valley transmitter.

2. 5G Broadcast - Rel-16
