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.
