Abstract: A user equipment (UE) for receiving control information in a wireless communication system includes a transceiver configured to receive a synchronization signal/physical broadcasting channel (SS/PBCH) block of an index i from a BS, wherein SS/PBCH block comprises a PBCH carrying master information block (MIB). The UE includes a processor configured to for the SS/PBCH block of the index i, determine a slot index n0 as a sum of an offset value and [i*M]. The offset value is determined based on a first value O determined according to the index indicated in the MIB, wherein the index configures PDCCH monitoring occasions, and a second value μ indicated in the MIB, wherein the second value μ represents a subcarrier spacing configuration, wherein M is a positive number determined according to the index indicated in the MIB, and cause the transceiver to decode a PDCCH in the slot index n0.
