The present document is related to the technical report for the study item "Study on Small Cell Enhancements for E-UTRA and E-UTRAN – Higher layer aspects" (RP-122033).

This activity involves the Radio Access work area of the 3GPP studies and has impacts both on the Mobile Equipment and Access Network of the 3GPP systems.

The present document gathers all technical outcome of the study item, and draws a conclusion on the way forward.
