Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz ~ 100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.
