A New Carrier Type, NCT, Secondary Component Carrier, SCC, activation control device, comprising: a measuring module configured to perform radio link measurement to an SCC by measuring at least one of a demodulation reference signal, DM-RS, and a channel status indicator reference signal, CSI-RS; and an activation control module configured to perform activation control to the SCC based on the measurement result; wherein the measuring module is configured to perform the radio link measurement to the SCC using at least one of the DM-RS and CSI-RS based on at least one configuration information of the DM-RS and CSI-RS; the radio link measurement performed by the measuring module to the SCC comprises radio link management, RLM, measurement, and the activation control module is configured to deactivate the SCC if the RLM measurement determines that a radio link failure, RLF, occurs to the SCC, wherein when performing the RLM measurement to the SCC, the measuring module is configured to measure a local frequency band of an enhanced physical downlink control channel, ePDCCH, and/or a physical downlink shared channel, PDSCH, using the DM-RS; the measuring module is further configured to, when the SCC has a radio link problem, RLP, during the RLM measurement, detect a cause of the RLP and report the cause to a base station; and the measuring module is configured to determine the cause of the RLP by detecting a type of the RLP, the type of the RLP comprises local frequency band deep fading and excessive local frequency band interference, and the measuring module is configured to measure a full frequency band of the SCC using at least one of the CSI-RS and a Reduced CRS, and compare the measurement result of the full frequency band and the measurement result of the local frequency band of the ePDCCH and/or the PDSCH to determine the type of the RLP, wherein when the measurement result of the local frequency band is lower than the measurement result of the full frequency band, the RLP type is determined as local frequency band deep fading, and, when the interference level of the local frequency band is higher than the interference level of the full frequency band, the RLP type is determined as excessive local frequency band interference; wherein the measuring module is further configured to perform radio link recovery, RLR, detection to the SCC, when performing the RLR detection, the measuring module is configured to perform a detection selected from the group consisting of RLR detection to a local frequency band of the SCC using the DM-RS, RLR detection to a full frequency band of the SCC using a Reduced CRS, and a combination thereof, and when the RLR detection determines that the SCC cannot recover from the RLP, the measuring module determines that the SCC has the RLF. a measuring module configured to perform radio link measurement to an SCC by measuring at least one of a demodulation reference signal, DM-RS, and a channel status indicator reference signal, CSI-RS;
