The objective of this study item is to

• study how to implement the requirements from SA1 as provided in TS 22.101, i.e.
• study impacts on E-UTRAN architecture and signalling interfaces, e.g. how to introduce means to quantify and monitor resources used by any participating operator
• study which changes are needed to relevant specifications for which RAN3 is responsible e.g. changes to S1 and X2 signalling
• co-operate with other TSGs/WGs in case some of the requirements would impact parts of the overall system which are out of scope of RAN3

The present document is a technical report of the study item for Study of RAN aspects of RAN Sharing Enhancements for LTE - Core Part which was approved at TSG RAN #62. The report provides background, analysis of the requirements set out in [1], and a list of recommended changes to the specifications.
