Abstract

A user equipment (UE) is preconfigured with Positioning Reference Signal (PRS) configurations for a plurality of base stations. The UE receives a base station almanac including position information and identifies of local base stations. Using the PRS configurations and information from the base station almanac, the UE receives PRS signals from a first set of base stations. The UE may also receive cell-specific reference signals (CRS) from a second set of base stations. The UE performs location determination for the user equipment using the PRS signals from the first set of base stations, the CRS signals from the second set of base stations.
