Claim:
1. A method for carrier aggregation operable by a mobile device in a wireless communication network, the method comprising: identifying a first component carrier, affiliated with a first cell, and a second component carrier, affiliated with a second cell, among a plurality of component carriers to be aggregated, wherein a first number of subframes of a subframe type in the first component carrier is less than a second number of subframes of the same subframe type in the second component carrier; receiving, on the first component carrier, a configuration to monitor a control channel for the second component carrier; determining a reference uplink-downlink subframe configuration for the second component carrier based at least in part on the subframe type and the received configuration for the control channel; and determining whether a hybrid automatic repeat request (H-ARQ) timing for data transmissions for the second component carrier follows a H-ARQ timing of the first cell or a H-ARQ timing of the second cell based at least in part on a format of an uplink control channel.
