The activation control device includes: 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 a measurement result. ## Claims ### Claim 1 A base station device configured to manage a carrier set of user equipment containing a New Carrier Type (NCT) Secondary Component Carrier (SCC), the base station device comprising: circuitry configured to: receive from the user equipment a result of radio link measurement of an SCC by using at least one of a demodulation reference signal (DM-RS) and a channel status indicator reference signal (CSI-RS); manage an activation status of the SCC contained in the carrier set of the user equipment based on a measurement result; configure at least one of the DM-RS and CSI-RS of the SCC based on a request to measure the NCT SCC from the user equipment, so that the user equipment performs the radio link measurement of the SCC using the at least one of the DM-RS and CSI-RS; and receive information reported by the user equipment after the user equipment performs radio link management (RLM) measurement of a physical downlink shared channel (PDSCH) using the DM-RS. ### Claim 2 (depends on 1) The base station device according to claim 1, wherein the circuitry is further configured to receive the information reported by the user equipment after the user equipment performs RLM measurement of an enhanced physical downlink control channel (ePDCCH). ### Claim 3 (depends on 2) The base station device according to claim 2, wherein the information which is reported by the user equipment comprises a cause of a radio link problem (RLP), and wherein the base station device further comprises a recovery assisting module configured to assist the user equipment in recovering from the RLP. ### Claim 4 (depends on 3) The base station device according to claim 3, wherein the circuitry is further configured to perform frequency diversity or frequency-domain position adjustment to corresponding ePDCCH and/or PDSCH when the cause of the RLP is local frequency band deep fading, and perform frequency-domain inter-cell interference coordination ICIC processing to the corresponding ePDCCH and/or PDSCH when the cause of the RLP is excessive local frequency band interference. ### Claim 5 (depends on 2) The base station device according to claim 2, wherein the circuitry is configured to set the SCC contained in the carrier set of the user equipment to be deactivated, when the information which is reported by the user equipment comprises an indication that the RLM measurement result is a radio link failure RLF of the SCC. ### Claim 6 (depends on 1) The base station device according to claim 1, wherein the circuitry is further configured to: receive from the user equipment a measurement result of the RRM measurement performed to the SCC using the at least one of the DM-RS and the CSI-RS; and set the SCC contained in the carrier set of the user equipment to be activated or deactivated based on the measurement result of the RRM measurement. ### Claim 7 A New Carrier Type (NCT) Secondary Component Carrier (SCC) management method configured to manage a carrier set of user equipment containing an NCT SCC, the management method comprising: receiving from the user equipment a result of radio link measurement performed to an SCC by using at least one of a demodulation reference signal (DM-RS) and a channel status indicator reference signal (CSI-RS); managing an activation status of the SCC contained in the carrier set of the user equipment based on a measurement result; configuring at least one of the DM-RS and CSI-RS of the SCC based on a request to measure the NCT SCC from the user equipment, so that the user equipment performs the radio link measurement to the SCC using at least one of the DM-RS and CSI-RS; and when receiving from the user equipment a result of radio link measurement of the SCC using the DM-RS, receiving information reported by the user equipment after the user equipment performs radio link management (RLM) measurement of a physical downlink shared channel (PDSCH) using the DM-RS. ### Claim 8 (depends on 7) The management method according to claim 7, further comprising: when receiving from the user equipment the result of radio link measurement of the SCC using the DM-RS, receiving information reported by the user equipment after the user equipment performs RLM measurement of an enhanced physical downlink control channel (ePDCCH). ### Claim 9 (depends on 8) The management method according to claim 8, further comprising: receiving a cause of a radio link problem (RLP) reported by the user equipment; and assisting the user equipment in recovering from the RLP based on the cause. ### Claim 10 (depends on 8) The management method according to claim 8, further comprising: when the received information reported by the user equipment comprises an indication that a result of the RLM measurement is a radio link failure (RLF) of the SCC, setting the SCC contained in the carrier set of the user equipment to be deactivated.
