Claim 0:
1. 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 a second bit sequence is obtained based on a first 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,
wherein the first bit sequence is obtained based on the bit sequence of the PBCH payload and a first scrambling sequence, and
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.
