Claim:
1. A method comprising: identifying a set of candidate uplink subframes and corresponding component carriers in a carrier aggregation configuration on which to transmit uplink feedback; determining a feedback delay associated with each of the candidate uplink subframes in the set of candidate uplink subframes; selecting an uplink subframe and corresponding component carrier from among the set of candidate uplink subframes based on the determined feedback delay associated with each of the candidate uplink subframes, wherein selecting the uplink subframe comprises determining a nearest uplink subframe of the set of candidate uplink subframes in which an uplink ACK/NACK is transmitted after a downlink subframe in which a physical downlink shared channel (PDSCH) is transmitted; and transmitting the uplink feedback via the selected uplink subframe and corresponding component carrier.
