5G-MAG members are engaging in global standardization activities around the 5G/IP and Media ecosystem. 5G-MAG members are able to propose relevant topics and areas of work in which 5G-MAG, as an association, should engage. 



The 3rd Generation Partnership Project (3GPP) unites seven telecommunications standard development organizations (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC) and provides their members with a stable environment to produce the Reports and Specifications that define 3GPP technologies.The project covers cellular telecommunications technologies, including radio access, core network and service capabilities, which provide a complete system description for mobile telecommunications. The 3GPP specifications also provide hooks for non-radio access to the core network, and for interworking with non-3GPP networks.

5G-MAG, in its role as 3GPP Market Representation Partner (MRP) can offer market advice to 3GPP and a consensus view of market requirements (e.g., services, features and functionalities) within 3GPP scope.



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)"
