Abstract
Systems and methodologies are described that facilitate transmitting low-density parity-check encoded communications in a wireless communications network and incrementing such codes in response to requests from receiving devices. The LDPC codes can have associated constraints allowing the codes to be error corrected upon receipt. The requests for incremented codes can be in cases of low transmission power or high interference, for example, where the original code can be too error-ridden to properly decode. In this case, additional nodes can be added to current and/or subsequent communications to facilitate adding a more complex constraint to the LDPC code. In this regard, the large codes can require less validly transmitted nodes to predict error-ridden values as the additional constraint renders less ambiguity in possible node value choices.
