1. A method of calculating a reverse link loading in an orthogonal frequency division multiple access wireless communication system, the method comprising:

  • estimating, at an access point, interference from at least one access terminal not being served by the access point, wherein estimating interference comprises;

    detecting a first pilot signal;

    detecting a second pilot signal that is contiguous to the first pilot signal in time or frequency; and

    subtracting the first pilot signal from the second pilot signal;

    measuring a receiver noise in a null time and frequency interval, the null time and frequency interval comprising at least one tone of the orthogonal frequency division multiple access wireless communication system; and

    comparing the interference to the receiver noise.
