Abstract:
A method and an apparatus for transmitting a resource, and a method for the HARQ retransmission using an unlicensed band include an operation of performing clear channel assessment (CCA) for the unlicensed band; and an operation of occupying a channel of the unlicensed band according to the CCA and determining whether or not the resource is transmitted based on a position of a transmission time interval (TTI) within a channel occupancy time (COT) for the channel.
