1. A method for optimizing clear channel assessment parameters comprising:

  • receiving a trigger condition;

    determining an upper bound and a lower bound for an energy detection threshold (EDT) parameter in response to the trigger condition;

    calculating a value of the EDT parameter by adding a current value of the EDT parameter and a product of a step size value multiplied by a weighted sum of;

    a received packet error rate divided by a target maximum received packet error rate,a transmitted packet error rate divided by a target maximum transmitted packet error rate, anda deferral rate divided by a target maximum deferral rate;

    bounding the EDT parameter by the upper bound and the lower bound; and

    updating the EDT parameter.
