Abstract
A New Carrier Type (NCT) Secondary Component Carrier (SCC) activation control device and method, an management method and a base station device. 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.
Claims10
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.
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.
