Mobile units in a multicarrier, multidimensional communications system can
assess their own channel coherence time attributes (base stations can
also access such dynamics for mobile units as well). This information is
utilized (either by the mobile unit itself or by an infrastructure
component such as a base site) to determine a level of trustworthiness
for other channel quality data as might be measured by the mobile unit.
Different modulation and coding schemes, along with responsive frequency
and time diversity resource allocations, are adaptively selected as a
function of this level of trustworthiness.
