5G-MAG does not create its own standards but helps the industry shaping those that we expect to play a role in the connected media ecosystem.

5G-MAG is injecting requirements into standard-making bodies, tracking their development and working on profiles, recommendations, development and implementation guidelines for the benefit of the industry.



5G Broadcast System for linear TV and radio services; LTE-based 5G terrestrial broadcast system 5G Broadcast System for linear TV and radio services

Go to the 5G-MAG Github for comments, bug-fixing, request for new features, etc.

The evolution of verticals in the context of 5G specifications also leads to the definition of technologies that enables the distribution of linear TV and radio services over 5G radio and core network technologies. This includes for example the ability to distribute free-to-air services to devices that are receive-only. The specific 3GPP technologies addressing the broadcaster’s needs, including:

- receive-only mode devices and services,
- MBMS dedicated carrier,
- extended numerologies for large inter-site distances,
- new core network interfaces and content transport mechanisms

are distributed over several 3GPP specifications and are under control of multiple different 3GPP working groups.
Beyond this, additional restrictions and profiling of existing 3GPP specifications are expected to be necessary that need to be documented in order to have deployment-ready specifications for 5G-based linear TV and radio services over cellular and broadcast networks. For example, existing core requirements on the 3GPP UE that may not apply to the receive-only mode devices receiving linear TV and radio services.
The objective of this work is to develop a single overview and system specification that

- profiles and restricts existing 3GPP specifications in the context of 5G in order to enable the deployment of linear TV and radio services,
- documents UE and network implementation guidelines to deploy linear TV and radio services, as necessary.

The work item is aligned with ongoing 3GPP standardization work, in particular the "LTE-based 5G terrestrial broadcast (LTE_terr_bcast)"
