Abstract: In a wireless communication system, a physical broadcast channel (PBCH) is encoded based on a Polar code and then is transmitted. Half-frame information within the PBCH is mapped to a bit position 247 among bit positions of the Polar code and synchronization signal and PBCH block (SSB) index information within the PBCH is mapped to bit positions 253, 254, and 255 of the Polar code.
