Some schemes for reporting an RS-SINR measured at user equipment to a base station are disclosed. One aspect of the present invention relates to user equipment, comprising: a measurement unit configured to measure an RS-SINR (Reference Signal-Signal to Interference and Noise Ratio) for a reference signal in a physical downlink control channel transmitted from a base station; and a reporting unit configured to report the measured RS-SINR to the base station in accordance with a predefined reporting trigger.
