METHOD FOR SIGNALING CONTROL INFORMATION, AND APPARATUS THEREFOR |
摘要 |
The present invention relates to a wireless communication system. In detail, the invention relates to a method for a terminal to transmit a UCI in a carrier aggregation-based wireless communication system, and to an apparatus therefor, wherein the method involves the steps of: forming a first cell group having a PCell; forming a second cell group having one or more SCells; receiving one or more data in the second cell group; and transmitting HARQ-ACK information on the one or more data through a PUCCH, wherein, when the first and second cell groups are managed by an identical base station, the HARQ-ACK information is transmitted in the PCell, and, when the first and second cell groups are managed by different base stations, the HARQ-ACK information is transmitted in the second cell group. |

1. A method for transmitting Uplink Control Information (UCI) by a User Equipment (UE) in a wireless communication system based on carrier aggregation, the method comprising:
configuring a first cell group having a Primary Cell (PCell); configuring a second cell group having one or more Secondary Cells (SCells); receiving one or more data in the second cell group; and transmitting Hybrid Automatic Repeat reQuest (HARQ)-ACKnowledgment (ACK) information for the one or more data on a Physical Uplink Control Channel (PUCCH), wherein if the first cell group and the second cell group are managed by the same Base Station (BS), the HARQ-ACK information is transmitted in the PCell, and if the first cell group and the second cell group are managed by different BSs, the HARQ-ACK information is transmitted in the second cell group. |
