Abstract
As the positioning technology in mobile networks develops, more and more research is focused on the algorithms. However, the accuracy of key parameters are also crucial, such as reference signal time difference(RSTD) in observed time difference of arrival (OTDOA) method and UE Rx-Tx in the enhanced cell identity (E-CID) method, which are both studied in this paper especially in the heterogeneous networking environments with the interference of low power nodes (LPNs). Two approaches, furthermore, are proposed to improve the accuracy of these parameters in order to access the positioning requirement of LTE-A system with excellent simulation performance.
