A method and apparatus for determining a mobile station's location using an antenna beam that traverses a scan pattern is described herein. In one embodiment, a device transmits/receives a signal as a position of a transmission/reception antenna beam traverses the scan pattern in a non-sequential order. A strength of the received signal is measured at a plurality of the beam positions. After reordering the signal strength measurements, the mobile station location relative to a nominal center of the beam is determined based on the reordered signal strength measurements. Another embodiment uses signals having different frequency components that are transmitted or received in beams executed in different scan patterns. In this embodiment, signal strength measurements associated with different frequency components are jointly processed to determine a combined correlation. The relative mobile station location is determined based on the combined correlation.
