Abstract
An apparatus and a method is described, by which a component carrier configuration, re-configuration, activation or de-activation is performed. In particular, a signaling format used for acknowledgment/negative acknowledgement messages on an uplink control channel is detected, and a codebook size of the acknowledgment/negative acknowledgement messages is decided based on the detected signaling format.
