MEASUREMENT OF A DOWNLINK POSITIONING REFERENCE SIGNAL FROM A NON-SERVING BASE STATION OF A USER EQUIPMENT AT A SERVING BASE STATION OF THE USER EQUIPMENT

Abstract:

In an aspect, a serving BS of a UE measures ToAs of a DL-PRS from a non-serving base station of the UE and an UL-SRS-P from the UE. The serving BS transmits measurement information based on the ToA measurements of the DL-PRS and the UL-SRS-P to a position estimation entity. The position estimation entity determines a positioning estimate for the UE based in part upon the measurement information.
