The present invention relates to a radio node (212), a wireless device (220) and methods performed by the radio node (212) and the wireless device (220) for communicating in a wireless communication system (200). The wireless device (220) is configured with cells on at least two component carriers, CCs, available to the wireless communication system (200) for communication with the wireless device (220). Each one of the at least two CCs is associated with at least one CC group out of a set of CC groups. The radio node (212) transmits control information to the wireless device (220)indicating a CC group. The transmitted control information applies to at least one CC, which at least one CC is at least one of those CCs, out of the at least two CCs, that are associated with the indicated CC group. The wireless device (220) receives the control information from the radio node (212) and applies the received control information to at least one CC, which at least one CC is at least one of those CCs, out of the at least two CCs, that are associated with the indicated CC group.
