## Abstract

A method for receiving a broadcasting signal in a wireless communication system. The method comprises receiving, from a base station (BS), a physical broadcasting channel (PBCH) content over a PBCH, and determining the PBCH content including a payload, wherein the payload includes uncommon information within a transmission time interval (TTI) of the PBCH that comprises at least a portion of a 10-bit system frame number (SFN), a half frame index within a radio frame, and at least part of a synchronization signal (SS) block time index.

generate least significant bits (LSBs) of the SFN and a half frame index on a second payload of the PBCH, and
