Abstract: A method by a terminal in a wireless communication system is provided. Downlink control information including modulation and coding scheme (MCS) information is received from a base station. A number of information bits are identified based on the downlink control information. A transport block size (TBS) is identified based on the number of information bits and a TBS candidate set. The TBS candidate set includes values separated by an interval among a plurality of intervals. Each of the plurality of intervals is a multiple of 8. A first interval between first consecutive values included in the TBS candidate set is larger than a second interval between second consecutive values included in the TBS candidate set. The first consecutive values are greater than or equal to a predetermined value, and the second consecutive values are less than the predetermined value.

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.
