Abstract: A base station, a wireless device and methods therein for supporting radio communication, wherein the base station employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station signals (3:3) an SCell status to the wireless device, the SCell status indicating whether the at least one SCell will be in active state where the base station transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.
