Abstract:
1. A method for transmitting Uplink Control Information (UCI), performed by user equipment, in a multi-carrier system, the method comprising: generating UCI for measuring a downlink component carrier (DL CC) configured in the user equipment; selecting a physical uplink shared channel (PUSCH) of one uplink component carrier according to an order of priority from PUSCHs of two or more uplink component carriers configured in the user equipment; and transmitting the UCI through the PUSCH of the selected uplink component carrier, wherein if acknowledgement (ACK)/non-acknowledgement (NACK), aperiodic Channel Status Information (CSI) and periodic CSI are included in the UCI transmitted by the user equipment, an order of priority in transmission is in order of the ACK/NACK, the aperiodic CSI and the periodic CSI, and wherein if the PUSCH of the selected uplink component carrier is not a PUSCH having a highest order of priority and has insufficient resources for transmitting all of the ACK/NACK, the aperiodic CSI and the periodic CSI, the ACK/NACK is firstly transmitted through the PUSCH of the selected uplink component carrier.
