Abstract
Embodiments improve User Equipment (UE) positioning accuracy in a mobile communication system by providing for a UE configured to listen for Positioning Reference Signal (PRS) transmissions within an operating bandwidth around Direct Current (DC) sub-carrier and at least one non-PRS transmission including, for example, a CRS or PSS/SSS; receiving, at the UE, PRS and non-PRS(s) transmissions transmitted from base stations within the operating bandwidth; performing, at the UE, Time of Arrival (TOA) measurements for each of the plurality of base stations, wherein the TOA measurements are determined based on the at least one non-PRS transmission; obtaining Observed Time Difference of Arrival (OTDOA) measurements by subtracting TOA for the plurality of base stations from a TOA for a reference base station, and transmitting, from the UE to a Location Server (LS), the OTDOA measurements, wherein the LS performs a positioning estimation of the UE based on the OTDOA measurements.
