WI Acronym:  FS_HetNet_eMOB_LTE
Rapporteur:  Dr. Palat, Sudeep

This TR is intended the capture the output of the Study Item on HetNet mobility improvements for LTE.
The study aims to look at various mobility improvements such as possible improvements to support seamless and robust mobility of users between LTE macro to pico cells in Heterogeneous networks, better strategies to identify and evaluate small cells, handover performance with and without eICIC features, improvements to re-establishment procedures etc. It is also expected to consider these in the context of Carrier aggregation in Home eNodeBs.
