1. A method for positioning a user equipment (UE) comprising:
calculating, at a location server, expected receiving time differences between respective expected times for the UE to receive positioning reference signals (PRSs) from a plurality of neighbor base stations respectively and an expected time for the UE to receive a PRS from a reference base station;
determining, at the location server, a PRS timing offset to at least partially compensate for the expected receiving time difference of at least one of the plurality of neighbor base stations; and
sending, by the location server, the PRS timing offset to the at least one of the plurality of neighbor base stations, wherein the PRS timing offset is determined in a case where the expected receiving time difference of the at least one of the plurality of neighbor base stations exceeds a threshold, and the determined PRS timing offset has a value to compensate for the expected receiving time difference of the at least one of the plurality of neighbor base stations to be within the threshold.
