Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system 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 initial deployment of mmWave/cmWave system is expected to operate as non-standalone system to provide additional radio resources to the UE which would be connected to the LTE-A cell for coverage purpose. The present disclosure covers initial access aspects of a UE on such future wireless system.
