Abstract

The present disclosure provides a method performed by a base station for enabling communication on an unlicensed spectrum and the base station. The method comprises: transmitting, by the base station, an Unlicensed-Discovery Reference Signal (U-DRS) on an unlicensed carrier. The base station can configure a UE with unlicensed carriers for the UE to monitor the U-DRS. The method can further comprise: transmitting, by the base station, a reference signal for measuring Channel State Information (CSI) on the unlicensed carrier. The base station can configure a UE with unlicensed carriers for the UE to measure CSI and receive downlink data. The method can further comprise: transmitting, by the base station, downlink data to the UE on the unlicensed carrier. The present disclosure further provides a method performed by a UE and the UE, corresponding to the above method and base station
