Method for performing a HARQ operation in a carrier aggregation with at least one SCell operating in an unlicensed spectrum and a device therefor
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a HARQ process in a carrier aggregation, the method comprising: configuring with a plurality of cells, wherein each of the plurality of cells belongs to one of a first cell group and a second cell group; receiving two sets of maximum number of Hybrid-ARQ (HARQ) transmission, wherein a first set is related to a first cell group and a second set is related to a second cell group; applying the first set to a HARQ process if the HARQ process is assigned to the first cell group; and applying the second set to the HARQ process if the HARQ process is assigned to the second cell group.
