Active Working Groups in 3GPP (link)

The standardization work on D2D technologies in 3GPP started in 2011 as part of the 3GPP Release 12 (Rel12), which is due to be “frozen” (i.e. no functional change permitted after this date) in June 2014. The work is done under the Work Item “Proximity Services” (or ProSe) and has well progressed, but the volume of required specifications to serve the identified requirements is largely exceeding the capabilities of 3GPP for Rel12 (given also the other topics of Rel12). The work on D2D technologies in 3GPP is focused on a set of use cases, which were identified to fit the needs of both public safety and commercial mobile networks.

The work on ProSe for Rel12 is now completed in SA WG1 (Requirements) where the Technical Specification TS 22.278 has been frozen. The work in SA WG2 (System Architecture) is reaching the end of the feasibility stage: the Technical Report (non-normative document) TR 23.703 has been assembled, compiling all proposed solutions for system architecture, and should be frozen in January 2014 at the latest, before the normative work starts to produce a proper Technical Specification. The work in RAN1 (Radio Layer1) is in the middle of the feasibility stage with compilation of proposal for solutions but also evaluation models (channel, traffic, mobility) in TR 36.843. The work in RAN2 (Radio Layer2 and Layer3-Radio Resource part) is in the first part of the feasibility stage, with discussions on core options for the design of the solution, and will partly have to wait for completion of the RAN1 work. The work in CT1 (Non-Access Stratum protocols) has not yet started and will mostly wait for the completion of the normative work in SA2.
