摘要：
Techniques for sending control information in a wireless network are disclosed. A multi-carrier user equipment (UE) may receive a downlink grant on a physical downlink control channel (PDCCH) on a first component carrier (CC). The UE may also receive a data transmission associated with the PDCCH on a physical downlink shared channel (PDSCH) on a second CC. In some examples, the UE determines physical uplink control channel (PUCCH) resources for acknowledging the data transmission based on the first CC on which the PDCCH is received, the second CC on which the data transmission is received, and a transmission mode of the second CC. The UE may send acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission based on the PUCCH resources.
