Abstract: A method for transmitting uplink control information by a communication apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system. Only one Physical Downlink Shared Channel (PDSCH) is received on the PCell among the plurality of cells in a first subframe. Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information about the PDSCH is transmitted through a Physical Uplink Control Channel (PUCCH) in a second subframe configured for Scheduling Request (SR) transmission. For a positive SR in the second subframe, the HARQ-ACK information is transmitted using a SR PUCCH resource. For a negative SR in the second subframe, the HARQ-ACK information is transmitted using a HARQ-ACK PUCCH resource different from the SR PUCCH resource.

Abstract: A method for transmitting an uplink signal by a user equipment (UE) in a wireless communication system. The method according to one embodiment includes receiving, by the UE, a physical downlink control channel (PDCCH) via one or more resource units; receiving, by the UE, a physical downlink shared channel (PDSCH) indicated by the received PDCCH; and transmitting, by the UE, a physical uplink control channel (PUCCH) using a PUCCH resource in response to the received PDSCH. An index of the PUCCH resource is determined by adding a first index offset and a second index offset to a lowest index of the one or more resource units. The first index offset is signaled via the PDCCH and the second index offset is signaled via higher layer signaling.
