5G-Xcast was one of the 5G-PPP Phase-II projects present at the 28th edition of European Conference on Networks and Communications, EuCNC 2019, held 18-21 June in Valencia (Spain). The conference, which gathered large amounts of experts from multiple industries, research centers, universities and business on telecommunications, was the ideal scenario to present our latest results on the design of a holistic multicast/broadcast solution for 5G systems.
As part of the project contribution to the 5G community in Europe and worldwide, multiple 5G-Xcast partners were heavily involved in different EuCNC activities like the showcasing of demos, the presentation of project results through conference papers and the participation of our experts in technical workshops.
Demos
As described in our online brochure, the project performed up to five demonstrations at the booth plus one additional joint demonstration located at the Sat5G booth.
The demonstration on “Converged, autonomous MooD in fixed/mobile networks” performed by BT and Expway showed how the content prepared for unicast distribution can be distributed over both fixed and mobile networks with dynamic switching between multicast/broadcast and unicast delivery depending on the audience size.
BBC in collaboration with University of Surrey presented the “Forecaster5G: Object-based broadcasting” showing how the content is produced as a set of discrete media objects to be rendered by the end device. Common objects were transmitted using the Dynamic Adaptive Streaming over IP Multicast (DASM) system while personalised content was received via unicast.
The demonstration on “Multimedia Public Warning” showcased the use of dynamic spectrum management, LTE broadcast and channel bonding to send public warning multimedia alerts to the user equipment. This demo was performed by One2many, LiveU, Fairspectrum, Turku University of Applied Sciences (TUAS) and Universitat Politecnica de Valencia (UPV)
Nomor in collaboration with BT, Broadpeak and Bundleslab presented the demo on “Reliable Multicast Delivery in 5G Networks” where the gains and trade-offs in resource consumption, spectrum efficiency, service coverage, and quality of experience introduced by multicast when delivering popular content were demonstrated.
The demonstration on “Hybrid Broadcast Service with Multi-Link” performed by Institut Für Rundfunktechnik (IRT), European Broadcasting Union (EBU), Bundleslab and LiveU showed the benefits of splitting and combining content from different networks via LTE and Wi-Fi interfaces, with a seamless switch between them and the ability to increase aggregated throughput via Multi-Link.
Finally, the “Low latency mABR live streaming 5G-Xcast SaT5G demo” joint demonstration showcased the use of satellite multicast capabilities for the delivery of live channels. The 5G-Xcast partners involved in this demonstration were Broadpeak and University of Surrey (UNIS).
During the conference, up to five different videos were filmed to explain the performance of our five 5G broadcast demonstrations. Stay tuned to our Youtube channel to discover all the technical details of our EUCNC 2019 demos.
Workshops
5G-Xcast also participated in the “International Workshop on 5G Architecture” . As representation of the project, David Navratil (Nokia Bell Labs Finland) presented the Chapter 4 on Core & Transport Architecture and was an active contributor to chapters 2, 3, 6 and 7. David Navratil was also involved in the subsequent panel session where different experts from other 5G-PPP projects were involved.
Papers
Dr. Belkacem Mouhouche (Samsung Electronics R&D UK) represented the 5G-Xcast project by presenting the paper on “A Method to Tailor Broadcasting and Multicasting Transmission in 5G New Radio” during the ThD3 – Radio Access Techniques session.
EUCNC 2019 was the ideal scenario to present the unprecedented 5G-Xcast outcome, which stands out as a global solution for the delivery of multiple services in mobile and broadcast networks thanks to the use of a single technology, 5G.
