(57) Abstract :
A method and apparatus for decoding encoded data bits of a wireless communication transmission are provided. A set of a-priori bit
values corresponding to known bit values of the encoded data bits may be generated. Decoding paths that correspond to decoded data
bits that are inconsistent with the a-priori bit values may be removed from the possible decoding paths to consider, and decoding the
encoded data bits by selecting a decoding path from remaining decoding paths of the possible decoding paths that were not removed.
A-priori bit values may be extracted from various messages, such as DL-MAP, UL-MAP, RNG-REQ, and BW-REQ messages.
