Claim Text:
1. A user equipment (UE) for communication in a wireless network supporting inter-EUTRAN Node B carrier aggregation, the UE comprising: a receiver to receive first downlink data from a first EUTRAN Node B (eNB) corresponding to a primary cell (PCell) in the wireless network, and to receive second downlink data from a second eNB corresponding to a secondary cell (SCell) in the wireless network; a processor configured to, in response to receiving the first downlink data, generate a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for the PCell, in response to receiving the second downlink data, generate a second HARQ-ACK for the SCell and further configured to select between use of a first physical uplink control channel (PUCCH) resource in the PCell and a second PUCCH resource in the SCell; and a transmitter configured to transmit, through the first PUCCH resource, first uplink control information (UCI) including the first HARQ-ACK for the PCell, and to transmit, through the second PUCCH resource, second UCI including the second HARQ-ACK for the SCell.
