Method for transmitting multiplexed HARQ feedbacks in a carrier aggregation system 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 first Physical Uplink Control Channel (PUCCH) group and a second PUCCH group, wherein at least two cells are configured with PUCCH resources in each of the first PUCCH group and the second PUCCH group;
generating, by the UE, a first Hybrid Automatic Repeat Request (HARQ) feedback by multiplexing HARQ feedbacks of all cells belonging to the first PUCCH group;
generating, by the UE, a second HARQ feedback by multiplexing HARQ feedbacks of all cells belonging to the second PUCCH group;
selecting, by the UE, a first cell among the at least two cells with the PUCCH resources in the first PUCCH group;
selecting, by the UE, a second cell among the at least two cells with the PUCCH resources in the second PUCCH group; and
transmitting, by the UE, the first HARQ feedback on the first cell and the second HARQ feedback on the second cell.

Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting multiplexed HARQ feedbacks in a carrier aggregation system, the method comprising: configuring a first Physical Uplink Control Channel (PUCCH) group and a second PUCCH group, wherein at least two cells are configured with PUCCH resources in each of the first PUCCH group and the second PUCCH group; generating a first Hybrid-ARQ (HARQ) feedback by multiplexing HARQ feedbacks of all HARQ processes of all cells belonging to the first PUCCH group; generating a second HARQ feedback by multiplexing HARQ feedbacks of all HARQ processes of all cells belonging to the second PUCCH group; selecting a first cell among the at least two cells with PUCCH resources in the first PUCCH group; selecting a second cell among the at least two cells with PUCCH resources in the second PUCCH group; and transmitting the first HARQ feedback on the first cell and the second HARQ feedback on the second cell.
