Classification: CPC H | IPC H

Claim 5:
6. A method of receiving a physical broadcast channel (PBCH) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving i) a synchronization signal/PBCH block (SS/PBCH block) including the PBCH and ii) a demodulation reference signal (DMRS) for the PBCH; and
obtaining a bit sequence of a PBCH payload, based on the PBCH,
wherein obtaining the bit sequence of the PBCH payload comprises:
obtaining a second bit sequence from the PBCH;
obtaining a first bit sequence based on the second bit sequence and a second scrambling sequence, wherein the second scrambling sequence and the DMRS are based on same bits of an index of the SS/PBCH block; and
obtaining the bit sequence of the PBCH payload based on the first bit sequence and a first scrambling sequence,
wherein the first scrambling sequence is based on 2nd and 3rd least significant bits of a system frame number (SFN) for a frame in which the PBCH is present.
