Method and device for transmitting and receiving control information and data in wireless communication system

A method of a second terminal in a wireless communication system, the method comprising:

• receiving a transport block from a first terminal through initial transmission or at least one retransmission;
• identifying a size of a frequency resource related to the initial transmission and a size of a frequency resource related to the at least one retransmission;
• and
• identifying a size of the transport block based on at least one of the size of the frequency resource related to the initial transmission and the size of the frequency resource related to the at least one retransmission,
• wherein the size of the frequency resource related to the initial transmission and the size of the frequency resource related to the at least one retransmission are different from each other.

A first terminal in a wireless communication system, comprising:

• a transceiver;
• and
• a controller configured to identify a size of a frequency resource related to initial transmission and a size of a frequency resource related to at least one retransmission, to identify a size of a transport block based on at least one of the size of the frequency resource related to the initial transmission and the size of the frequency resource related to the at least one retransmission, and to transmit a transport block according to the size of the transport block to a second terminal through the initial transmission or the at least one retransmission,
• wherein the size of the frequency resource related to the initial transmission and the size of the frequency resource related to the at least one retransmission are different from each other.
