Abstract

A user equipment (UE) can include processing circuitry configured to decode physical broadcast channel (PBCH) information received from a base station (BS). The decoded PBCH information includes a scrambled PBCH payload and an unscrambled bit sequence. A scrambling sequence is generated based on time information signaling within the unscrambled bit sequence. The scrambled PBCH payload is de-scrambled using the scrambling sequence, to obtain master information block (MIB) information. System information block (SIB) information is decoded based on the MIB information. The decoded PBCH information includes cyclic redundancy check (CRC) information. The scrambled PBCH payload and the unscrambled bit sequence can be verified based on the CRC information. The time information signaling includes one or more bits of a system frame number (SFN).
