1. Radio Frequency (RF) communication circuitry comprising: baseband processing circuitry operable to perform a substantial portion of Physical (PHY) layer operations supported by the RF communication circuitry by receiving analog signals corresponding to the data block, sampling the analog signal to produce samples corresponding to the data block, and to equalize the samples to produce soft decision bits of the data block; system processing circuitry operable to perform a substantial portion of Media Access Control (MAC) layer operations supported by the RF communication circuitry including receiving the soft decision bits of the data block from the baseband processing circuitry, prior to executing at least some of the MAC layer operations on the soft decision bits, determining that Incremental Redundancy (IR) operations are required for the soft decision bits of the data block, and initiating IR operations based upon the determination; and IR processing module circuitry operable to receive the soft decision bits of the data block, to receive a direction from the system processing circuitry to perform IR operations on the soft decision bits of the data block, and to perform IR operations on the soft decision bits of the data block.
