Claim of US Patent No. 10,602,535

1. A method of transmitting a physical broadcast channel (PBCH) by a transmitting device in a wireless communication system, the method comprising:mapping information for the PBCH to input bit positions of a Polar code of size N=512, based on a Polar sequence;
encoding the information based on the Polar code; and
transmitting the PBCH including the information encoded based on the Polar code,
wherein the information for the PBCH includes (i) half-frame information and (ii) synchronization signal and PBCH block (SSB) index information,
wherein the half-frame information is 1 bit and is mapped to input bit position 247 among input bit positions 0 to 511 of the Polar code based on the Polar sequence, and
wherein the SSB index information is 3 bits and is mapped to input bit positions 253, 254, and 255 among the input bit positions 0 to 511 of the Polar code based on the Polar sequence.
