Abstract:
A method by which terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting codeblock groups (CBGs) to a base station by using a first resource within the unlicensed band; and re-transmitting at least one CBG, in which a negative acknowledgement (NACK) is received, of the CBGs to the base station by using a second resource within the unlicensed band, wherein the second resource is determined on the basis of the proportion of the CBGs to the at least one CBG in which the NACK is received.
