| TD-LTE is one of the most important issues in current wireless network construction and implementation. There has been an obvious requirement for network depth coverage with the rapid development of mobile internet. This thesis presents a comprehensive research on TD-LTE depth coverage technology based on actual network optimization project in Gansu Mobile.A brief intruduction of TD-LTE principles and mahor technologies are presented, followed by the situation analysis of current TD-LTE network depth coverage. Some key techniques for heterogeneous network based depth coverage are analyzed. Finally, a specific implementation scenario for TD-LTE depth coverage is proposed based on actual TD-LTE coverage project in Lanzhou. |
