1. A channel quality reporting method for use by a wireless terminal, the method comprising:

  • measuring at least one of an amplitude or a phase of a first pilot signal corresponding to a first pilot tone to produce a first measured signal value;

    generating a first channel quality indicator value from the first measured signal value according to a first function which uses at least the first measured signal value as an input;

    transmitting the first channel quality indicator value, wherein transmitting the first channel quality indicator value includes;

    incorporating the first channel quality indicator value into a first message; and

    transmitting the first message over a wireless communications link;

    measuring at least one of an amplitude or a phase of a second pilot signal corresponding to a second pilot tone to produce a second measured signal value, the second pilot signal having a different transmission power than the first pilot signal;

    generating a second channel quality indicator value from the second measured signal value according to a second function which uses at least the second measured signal value as an input; and

    transmitting the second channel quality indicator value, wherein transmitting the second channel quality indicator value includes;

    incorporating the second channel quality indicator value into the first message; and

    transmitting the second channel quality indicator value with the first value in the first message over the wireless communications link.
