Abstract

For communication utilizing polar codes, a hybrid automatic repeat request algorithm utilizing incremental redundancy (HARQ-IR) may provide increased throughput by including new data, not based on an original transmission, in a HARQ retransmission. The number of retransmitted bits and new information bits in each HARQ retransmission may be controlled in order to manage a tradeoff between increased throughput and a decreased block error rate (BLER).
