Classification: CPC H | IPC H

Claim 12:
13. A base station in a wireless communication system, the base station comprising:
a transceiver configured to transmit or receive; a signal; and
a controller configured to:
transmit, to a terminal, first downlink control information (DCI) scheduling a transport block (TB), the first DCI including modulation and coding scheme (MCS) information for the TB, time domain resource information for the TB, and frequency domain resource information for the TB,
transmit, to the terminal the TB including a plurality of code blocks based on the first DCI,
receive, from the terminal, hybrid automatic repeat request (HARQ) information associated with a decoding failure of at least one code block among the plurality of code blocks,
transmit, to the terminal, second DCI scheduling a retransmission associated with the at least one code block, the second DCI including MCS information for the at least one code block, time domain resource information for the at least one code block, frequency domain resource information for the at least one code block, and information indicating whether the at least one code block is combinable, and
transmit, to the terminal, the at least one code block based on the second DCI,

wherein the at least one code block is decoded with an earlier transmitted at least one code block, in case that the information indicating whether the at least one code block is combinable indicates a first value, and
wherein the at least one code block is decoded without the earlier transmitted at least one code block, in case that the information indicating whether the at least one code block is combinable indicates a second value.
