Abstract: A method for improved frequency assignment includes recording handoff statistics for subscriber units handing into and out of a base station (130). The handoff statistics include the IDs of the other base stations (240) involved in the handoff, along with the date and time of the handoff. The statistics of the handoff count are applied based on the number of occurrences within a time period (450), and are used to accept or reject the potential frequency assignments obtained from an assignment algorithm. In one embodiment of this algorithm, using a Q estimate, obtained from residual powers recorded on each frequency (435), a candidate frequency is chosen based on the lowest Q value. This candidate is tested against the handoff statistics, and if rejected, a frequency with the next lowest Q level is tested. This process is repeated until a frequency is assigned.
