NCT SCC activation control device and method, management method and base station device

A New Carrier Type (NCT) Secondary Component Carrier (SCC) activation control device, comprising:

• circuitry configured to
• perform, using fixed resources, a radio link measurement to an SCC by measuring a demodulation reference signal (DM-RS) and a channel status indicator reference signal (CSI-RS) to generate a measurement result, a position of the fixed resources being prestored in the activation control device;
• and
• perform activation control to the SCC based on the measurement result;
• wherein the radio link measurement to the SCC is performed based on configuration information of the DM-RS and CSI-RS, and the radio link measurement comprises a radio link management (RLM) measurement,
• wherein, when performing the RLM measurement to the SCC, the circuitry is further configured to measure an enhanced physical downlink control channel (ePDCCH) using the DM-RS,
• wherein, when the SCC has a radio link problem (RLP) during the RLM measurement, the circuitry is further configured to detect a cause of the RLP and report the cause to a base station, and
• wherein the circuitry is further 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 circuitry 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 a measurement result of the full frequency band and a measurement result of a local frequency band of the ePDCCH to determine the type of the RLP.
