Classification: CPC H | IPC H

Claim 9:
10. An apparatus within a receiving device for decoding information of a wireless transmission from a transmitting device, the apparatus comprising:
a controller coupled to a buffer memory and operable to receive log-likelihood ratios (LLRs) of received data frames and LLRs of received redundancy frames and to store LLRs in the buffer memory;
an 802.11 decoder operable to decode codewords of the received data frames and pass decoded bits of the codewords to an 802.11 MAC interface, wherein the 802.11 decoder is coupled to the controller;
an 802.11 MAC interface coupled to the controller and the 802.11 decoder, wherein the 802.11 MAC interface is operable to provide an indication to the controller identifying failed data frames of the received data frames; and
a redundancy decoder coupled to the controller and the 802.11 MAC interface and operable to receive instructions from the controller to decode bits of the failed data frames using LLRs stored in the buffer memory,
wherein the controller is further operable to clear the buffer memory when all bits of the failed data frames are decoded successfully as indicated by the 802.11 MAC interface.
