NR-PBCH carries 32 information bits and 24 CRC bits. Specifically, NR-PBCH uses 512-bit Polar codes to carry total 56 data bits. Different Polar code bit channels have different channel reliability. As a general rule, the most reliable Polar code bit channels are used for the 56 data bits. In accordance with a novel aspect, within the 32 NR-PBCH information bits, some of the information bits that can be known to the decoders under certain conditions and therefore are placed at the least reliable Polar code bit positions. As a result, by mapping the NR-PBCH data bits properly at the input bit positions of Polar codes, the NR-PBCH decoding performance is improved when the known bits a priori can be exploited."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Broadcast channel enhancement with polar code","description":"A method of new radio physical broadcast channel (NR-PBCH) bit mapping is proposed to improve for NR-PBCH decoding performance under Polar codes.
