| Abstract: |
| The Long Term Evolution-Hotspot/indoor(LTE-Hi) system proposed by the 3rd Generation Partnership Project(3GPP)in Release-12(R12) plays an important role in solving the problem of the increasing data traffic indoor or in hotspot areas.After briefly introducing the deployment scenarios and requirements of LTE-Hi,this paper discusses part of the key technologies which are involved in the system.The current research on small cell on-off switching mechanisms and strategies,discovery technologies and radio-interface based synchronization is analyzed particularly.Finally it presents several possible future research directions of LTE-Hi in hope of providing reference for those concerned. |
