Abstract: Aspects of the disclosure provide a method and device performing input bit allocation that includes receiving broadcasting information bits, generating timing related bits for the broadcasting information bits, and selecting a portion of the generated timing related bits. The method and device can further include allocating each of the selected timing related bits to selected input bits of an encoder, so that each of the selected timing related bits is allocated to an input bit of the encoder corresponding to an available bit channel of the encoder where the selected inputs bits of the encoder correspond to encoded bits that are located in a front portion of the encoded bits.

Abstract: A method of new radio physical broadcast channel (NR-PBCH) bit mapping is proposed to improve for NR-PBCH decoding performance under Polar codes. 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.
