Abstract:
A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. At least one of the second radio station (2) and the radio terminal (3) is configured to transmit, to the first radio station (10), information about a problem occurring in a radio link in the second cell (20) between the second radio station (20) and the radio terminal (30) while the carrier aggregation of the first cell (10) and the second cell (20) is being performed.
