US 2026/0074826 A1 · CYCLIC REDUNDANCY CHECK AND PARITY CHECK GENERATION FOR SYSTEMATIC POLAR CODING

Abstract

Methods, systems, and devices for wireless communications are described. A wireless communication device may perform a systematic polar coding procedure including a first polar transform and a second polar transform such that a generated codeword includes information bits. For example, the wireless communication device may generate error check bits, such as cyclic redundancy check (CRC) or parity check (PC) bits, insert the error check bits prior to or after the first polar transform, and apply the first polar transform and the second polar transform to generate the codeword. In some examples, the wireless communication device may generate the error check bits such that the error check bits satisfy conditions associated with the systematic polar coding procedure. The wireless communication device may output the codeword based on the polar coding procedure, where the codeword includes the information bits.
