Patent ID: 8768264

Claim:
A wireless communication apparatus operable in a communication system, the wireless communication apparatus comprising: a channel estimator module configured to determine, via a processor, a variation in channel condition of at least one carrier frequency in a plurality of carrier frequencies designated for communicating the information, the variation being indicative of a channel condition for the at least one carrier frequency relative to at least one of a prior channel condition and a reference channel; a determination module configured to determine via a processor when a first criterion is satisfied, wherein the determination of when the first criterion is satisfied is based on, at least in part, comparing the variation in channel condition to a channel state model representative of channel state transition probabilities; and a communication module configured to communicate via a processor from a receiver to a transmitter data indicative of the variation in channel condition for the at least one carrier frequency when the determination module determines that the variation in channel condition satisfies the first criterion based on, at least in part, the comparison of the variation in channel condition to the channel state model representative of channel state transition probabilities.
