A user equipment (UE) for communication in a wireless network supporting inter-EUTRAN Node B (eNB) carrier aggregation has a receiver to communicate with a first eNB corresponding to a primary cell (PCell) in the wireless network and a second eNB corresponding to a secondary cell (SCell) in the wireless network. The receiver is configured to receive downlink data through a physical downlink shared channel (PDSCH) in the SCell. The UE has a processor configured to, in response to receiving the downlink data, generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SCell. A transmitter of the UE is configured to transmit, through a first physical uplink control channel (PUCCH) in the PCell, uplink control information (UCI) including the HARQ-ACK for the SCell. |
