A user equipment, UE, apparatus configured to detect an unlicensed cell, Uscell, wherein the apparatus comprises: an obtaining unit, configured to obtain detection indication information from a base station, wherein the detection indication information instructs the apparatus to measure a reference signal corresponding to the Uscell; and the detection indication information instructs the apparatus to detect and report information about the Uscell, wherein the information about the Uscell comprises content of the reference signal corresponding to the Uscell; the apparatus further comprising: a detection unit, configured to detect the information about the Uscell by using the detection indication information obtained by the obtaining unit; and a reporting unit, configured to report a detection result detected by the detection unit to the base station, characterized in that the obtaining unit comprises: a receiving subunit configured to receive reference signal measurement reporting information sent by the base station and use the reference signal measurement reporting information as the detection indication information; wherein the detection result indicates a result of identifying the Uscell; or the detection result indicates a measurement result of the reference signal corresponding to the Uscell; or the detection result comprises a distance difference indicating whether the UE is in proximity to the Uscell; and, when the detection indication information is the reference signal measurement reporting information, and when the detection result includes the CQI of the Uscell, the detection result indicates a pilot to which the CQI relates and a level of the CQI. an obtaining unit, configured to obtain detection indication information from a base station, wherein the detection indication information instructs the apparatus to measure a reference signal corresponding to the Uscell;
