摘要： A device may identify that an incremental redundancy hybrid automatic repeat request (IR-HARQ) scheme is used in association with sequential transmissions of an information bit vector to or from another wireless device, where each transmission in the scheme is associated with a resource size. The device may identify a mother code length for a polar code based at least in part on an aggregate resource size associated with the sequential transmissions. The device may identify an adjusted bit index set for the polar code based at least in part on the IR-HARQ scheme. The device may transmit (or receive), for each transmission of the information bit vector, a respective subset of encoded bits generated by mapping the information bit vector to a set of polarized bit channels of the polar code in accordance with the bit index set.
