The present document contains the result of the study item "Small Cell Enhancements for E-UTRA and E-UTRAN – Physical-layer Aspects".

The purpose of the present document is to help TSG RAN WG1 to define and describe the potential physical layer small cell enhancements under consideration and compare the benefits of each enhancement technique, along with the complexity evaluation of each technique.

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 is intended to gather all information and draw a conclusion on a way forward.

The present document is a 'living' document, i.e. it is permanently updated and presented to TSG-RAN meetings.
