12. A base station for transmitting or receiving data, the base station comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
determine whether to respectively allocate a plurality of transport blocks (TBs) including a first TB and a second TB to different frequency resource regions, based on frequency channel condition including signal to interference plus noise ratio (SINR),
determine, based on a result of the determining, at least one frequency resource region to which the first TB and the second TB are allocated, wherein the first TB is coded with a first modulation and coding scheme (MCS) and the second TB is coded with a second MCS,
transmit, to a terminal, first downlink control information including an indicator of a transmission mode which indicates whether the first TB and the second TB are allocated to the different frequency resource regions and resource allocation information for the first TB and the second TB, and
transmit, to the terminal, the first TB and the second TB in a physical downlink shared channel (PDSCH), based on the transmission mode,
wherein, in case that the indicator of the transmission mode indicates a first value;
the resource allocation information includes a first bit field comprising M bits indicating a frequency resource region allocated to the first TB and a second bit field comprising M bits indicating a frequency resource region allocated to the second TB,
a frequency resource allocation unit is identified as 2N, and
SINR of the frequency resource region allocated to the first TB is different from SINR of the frequency resource region allocated to the second TB, and
wherein, in case that the indicator of the transmission mode indicates a second value;
the resource allocation information includes a third bit field comprising 2M bits indicating a frequency resource region allocated to the first TB and the second TB, and
the frequency resource allocation unit is identified as N.
