Abstract
A method for scheduling radio resource in an unlicensed spectrum and a base station using the method is provided. This method includes following steps. Downlink data are obtained, and the first starting time point for a downlink transmission of this downlink data is estimated. A plurality of second starting times are set according to the first starting time point. A plurality of downlink control information (DCIs) for the downlink data are prepared before the earliest second start time point. Each of the DCIs is corresponding to each of the first start time point or the second start time points, and each of the DCIs points to a radio resource block of the downlink data. Clear Channel Assessment (CCA) procedure in the unlicensed spectrum is performed, and the DCIs are disposed in a physical downlink control channel (PDCCH) after the channel process is completed.
