A mobile device position determination method includes: determining a plurality of bandwidths of a pilot signal corresponding to different times at which the pilot signal is received by a mobile device from a base station, the plurality of bandwidths of the pilot signal including a first bandwidth corresponding to a first time at which the pilot signal is received and a second bandwidth corresponding to a second time at which the pilot signal is received, the second time being after the first time; filtering the pilot signal using the second bandwidth; determining a positioning parameter from the pilot signal filtered using the second bandwidth; and determining a position of the mobile device using the positioning parameter.
