Interleaving NR PBCH payload including known bits before CRC coding to enhance polar code performance

Abstract

Systems and methods are described herein that allow the information carrying bits of a transmission block to be placed at higher-reliability positions prior to transmission. An exemplary method includes generating a set of payload bits to be encoded for transmission, wherein the set of payload bits includes at least one known bit; interleaving the set of payload bits to generate an interleaved setof payload bits, wherein the interleaved set includes the at least one known bit in a predetermined position in the interleaved set; providing the interleaved set to a cyclic redundancy check (CRC) encoder to generate CRC-interleaved set of payload bits, wherein the CRC-interleaved set includes the at least one known bit in a predetermined position within the CRC-interleaved set, and encoding theCRC-interleaved set for transmission to a wireless device. The associated network nodes and wireless devices are included.
