1. A terminal apparatus comprising:
a receiver configured to receive RRC signaling; and
a processing unit,
wherein the processing unit determines whether information (first information) indicating whether a state of a secondary cell group is to be changed based on information (scg-State) indicating configuration of a state of the secondary cell group is included in the RRC signaling,
in a case that the first information is not included in the RRC signaling, the state of the secondary cell group is determined to be a deactivated state based on the scg-State being included in the RRC signaling, and the state of the secondary cell group is determined to be an activated state based on the scg-State not being included in the RRC signaling, and
in a case that the first information is included in the RRC signaling, the state of the secondary cell group is not changed based on whether the scg-State is included in the RRC signaling.
