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.

主权项

1. A method for transmitting Uplink Control Information (UCI) by a User Equipment (UE) in a wireless communication system, 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); and transmitting Channel Status Information (CSI) related with the second cell group via 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 CSI is transmitted in the PCell, and if the first cell group and the second cell group are managed by different BSs, the CSI is transmitted in the second cell group.
