A first set of control decoding candidates corresponding to a first transmit time interval length in a subframe can be monitored when a device is not configured to communicate using a second transmit time interval length in the subframe. The second transmit time interval length can be shorter than the first transmit time interval length. A second set of control decoding candidates corresponding to the first transmit time interval length in the subframe can be monitored when the device is configured to communicate using the second transmit time interval length in the subframe. The first and the second sets can be different. A number of candidates in the second set can be less than a number of candidates in the first set.
