METHOD AND DEVICE FOR POLAR CODE RETRANSMITTION Russian patent published in 2018 - IPC H04L1/08 H03M13/13 

FIELD: communication equipment; data processing.

SUBSTANCE: invention relates to communication system technologies and is intended for retransmission of a polar code. In embodiments of the present invention, certain information bits of a first polar code are encoded, to obtain a second polar code, where the first polar code is a codeword that is transmitted for the first time; addition modulo 2 is performed with respect to the first polar code and the second polar code to obtain a third polar code; and the third polar code is sent as a codeword to be retransmitted. Solutions provided in the embodiments of the present invention are applicable when a polar code is retransmitted.

EFFECT: improving the quality of communication by improving the performance of HARQ.
