摘要： A method is provided for transmitting an uplink (UL) control signal in a carrier aggregation (CA) system including a plurality of UL component carriers (CCs). A user equipment (UE) determines whether a simultaneous transmission of a physical UL control channel (PUCCH) and a physical UL shared channel (PUSCH) is configured. If the simultaneous transmission of the PUCCH and the PUSCH is not configured, the UE determines whether the PUSCH is scheduled in a primary CC (PCC) or in any secondary CCs (SCCs) of the CA system. If the PUSCH is not scheduled in the PCC, but is scheduled in the any SCCs, the UE selects one SCC from the any SCCs in which the PUSCH is scheduled according to a priority which is set by higher layer signaling. The UE piggybacks and transmits a UL control information (UCI) of the PCC on the PUSCH of the selected SCC.
