Abstract

Position location (PL) of a UE requesting E-911 services should be provided by wireless communication service providers, according to the Federal Communications Commission (FCC) regulations. Raising pilot power fraction can improve the system locatability, while it may also cause pilot pollution and increase interference to UEs in neighboring cells. In this letter we find the optimal pilot power allocation subject to coverage and locatability constraints. The results have shown that with new localization techniques such as Idle Period Downlink (IPDL) and Cumulative Virtual Blanking (CVB), the coverage and locatability constraints can be satisfied without requiring long integration time and large pilot power fraction.
