Incremental redundancy and variations for polar codes

Abstract:

Methods of transmitting blocks of incremental redundant coded bits are provided. Methods include concatenating, using an outer encoder, bits of an input bit vector to an outer encoded bit vector that has fewer bits than the input bit vector, wherein the outer encoded bit vector includes a mixture of information bits from the input bit vector. Methods include encoding the outer encoded bit vector into inner encoded data that is mapped to multiple data transmission channels that each include a channel reliability value. A first portion of the data transmission channels is used to transmit information bits corresponding to the outer encoded bit vector and a second portion of the data transmission channels is used to transmit frozen bits that include no information.
