METHOD AND DEVICE FOR TRANSMITTING CONTROL INFORMATION

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and device for transmitting uplink control information when a plurality of cells are configured in a wireless communication system, the method comprising the steps of: generating a UCI; and determining a PUCCH resource for transmitting the UCI. If the reception response information and channel state information are triggered in the same subframe, only a first UCI generated from the reception response information is transmitted through a first PUCCH. If the reception response information and scheduling request information are triggered in the same subframe, a second UCI generated by jointly coding the reception response information and the scheduling request information is transmitted through a second PUCCH. The resource used for a reference signal for demodulating the first or second PUCCH is allocated in consideration of the UCI transmitted on PUCCH.
