1. A base station comprising:a transceiver; and
a controller coupled with the transceiver and configured to:
generate most significant bits (MSBs) of a system frame number (SFN) and a physical downlink control channel (PDCCH) configuration for system information on a first payload of a physical broadcast channel (PBCH),
generate least significant bits (LSBs) of the SFN and a half frame index on a second payload of the PBCH, and
transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and the PBCH,
wherein one cyclic redundancy check (CRC) is defined based on both the first payload and the second payload.
