description Methods, systems, and devices for wireless communication are described. A first wireless device may transmit, to a second wireless device, a codeword corresponding to a set of information bits encoded using a polar code, and the second wireless device may obtain a first set of log likelihood ratios (LLRs) based on performing a first decoding operation on the codeword. In cases that the first wireless device identifies a failure of the second wireless device to decode one or more of the information bits, the first wireless device may retransmit a subset of the information bits to the second wireless device independently of the polar code. The second wireless device may then attempt to decode the codeword a second time using the polar code and based on a combination of a first set of LLRs and a second set of LLRs corresponding to the subset of the information bits.
