摘要

The disclosed embodiments herein relate to a method performed by a UE (110); a UE (110), a method performed by a location server (120) and a location server (120) and computer programs respectively. The method performed by the UE (110) comprises: receiving (401) from a location server NetWork assisted Reference Signal Time Difference, RSTD, Quantization Information, NW-QI; performing (402) RSTD measurements by measuring or estimating a Time Of Arrival, TOA, of a Positioning Reference Signal, PRS, from respective base station of a plurality of base stations; encoding (403) the RSTD measurements by employing a Enhanced RSTD Quantization Method, E- QM, or by using the NW-QI while encoding the RSTD measurements; and sending (404) UE assisted RSTD Quantization Information, UE-QI, to the location server, the UE-QI including the encoded RSTD measurements.
