Abstract
Various embodiments may provide systems and methods for supporting lossy compression of feedback information, such as acknowledgment (ACK) information, negative acknowledgement (NACK) information, etc. Various embodiments may support lossy compression for feedback messages in retransmission systems, such as Hybrid Automatic Repeat Request (HARD) protocols, the Multiple Incremental Redundancy Scheme (MIRS), etc. Various embodiments may support compression of feedback bits using a different compression codebook per symbol or per group of symbols. Various embodiments may support selection of a compression codebook per symbol, or per group of symbols, based at least in part on a probability of successful decoding of each code block in the symbol or group of symbols.
