1. A base station, comprising:
radio frequency (RF) circuitry configured to communicate with a user equipment (UE) in a fifth generation (5G) network; and
a processor communicatively coupled to the RF circuitry and configured to perform operations, comprising:
configuring one or more parameters for a 5G master information block (MIB), wherein the 5G MIB comprises a downlink system bandwidth, a 5G physical downlink control channel (PDCCH) configuration and a system frame number, SFN;
generating a 5G physical broadcast channel (PBCH) from the 5G MIB, wherein a cyclic redundancy check (CRC) is attached to the 5G MIB;
applying a Demodulation Reference Symbol (DM-RS) based transmission for the 5G PBCH, wherein a same beamforming weight is applied for the DM-RS and for data symbols allocated for the 5G PBCH; and
transmitting the 5G MIB via the 5G PBCH on a predefined resource and a 5G frequency band over 6 giga hertz (GHz).
