The 5G-ROSE project worked towards the transmission of 5G broadcast services over SFN virtualized networks, using opensource software.
The project is very well aligned with the current trends in the world of 5G. On one side, the virtualisation of the 5G infrastructure, both core and RAN (Radio Access Network), allowing for different deployment architectures with maximum flexibility and scalability. On the other side, the adoption of so-called LTE-based 5G Terrestrial Broadcast mode, which is currently under standardization in 3GPP Release-16, and that will meet the requirements of broadcasters
for the distribution of media content in 5G.
5G-ROSE has made use of the virtualised IRIS testbed at Trinity College Dublin. The project has
used and contributed to the open source SDR LTE software suite srsLTE, offered by Software
Radio Systems. The 5G-ROSE project consisted of three clearly differentiated, but related,
broadcast experiments over a virtualised SDR (Software Defined Radio) access infrastructure.
The first experiment was the development and testing of the first virtualized Multimedia
Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission. The second experiment dealt with the introduction of 5G physical layer Release (Rel)-16 specific components. The third part was about the combination of both unicast and broadcast transmissions by means of network slicing.
