Proximity-based applications and services represent an emerging social-technological trend. The introduction of a
Proximity Services (ProSe) capability in LTE allows the 3GPP industry to serve this developing market, and, at the
same time, serve the urgent needs of several Public Safety communities that are jointly committed to LTE (see SP120456 (MoU between TETRA & Critical Communications Association (TCCA) & the National Public Safety
Telecommunications Council), and S1-121247 (TCCA)).
Additionally, the study on LTE Device to Device Proximity Services (FS_LTE_D2D_Prox, TR 36.843
) has shown that
with the current status of work, adding D2D discovery and broadcast communication techniques is considered
compatible to the LTE standard. Meanwhile, normative work on proximity services has been *completed* in SA2 (TS 23.303
) and a corresponding WID for stage-3 work (C1-140748) is also being submitted for approval.
ProSe specification is important to enable economy of scale advantages, i.e. the resulting system can be used for both
Public Safety and non-Public-Safety services, as much as possible.
The purpose of the present document is to study the radio requirements LTE Device to Device Proximity Services as
part of the Rel-12 work item. The normative requirements resulting from the present document will be addressed in the
applicable release 12 Technical Specifications (TS).
