Method for performing a HARQ operation in a carrier aggregation with at least one SCell operating in an unlicensed spectrum and a device therefor
First Claim
1. A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:
- configuring with a plurality of cells, each of the plurality of cells belonging to a first cell group or a second cell group;
receiving two sets of a maximum number of Hybrid-ARQ (HARQ) transmissions, a first set related to a first cell group and a second set 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,wherein a maximum number of HARQ transmissions for the second set is larger than a maximum number of HARQ transmissions for the first set if all cells in the first cell group operate in a licensed spectrum and all cells in the second cell group operate in an unlicensed spectrum.

Abstract
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.

8. A User Equipment (UE) operating in a wireless communication system, the UE comprising:
-
a Radio Frequency (RF) module configured to transmit and receive signals; and a processor configured to; configure with a plurality of cells, each of the plurality of cells belonging to a first cell group or a second cell group; control the RF unit to receive two sets of maximum number of Hybrid-ARQ (HARQ) transmissions, a first set related to a first cell group and a second set related to a second cell group; apply the first set to a HARQ process if the HARQ process is assigned to the first cell group; and apply the second set to the HARQ process if the HARQ process is assigned to the second cell group, wherein a maximum number of HARQ transmissions for the second set is larger than a maximum number of HARQ transmissions for the first set if all cells in the first cell group operate in a licensed spectrum and all cells in the second cell group operate in an unlicensed spectrum. - View Dependent Claims (9, 10, 11, 12, 13, 14)
