The embodiments of the present disclosure provide a method for configuring scheduling signaling on an unlicensed carrier. The method includes: configuring, by a base station, a carrier scheduling configuration message of a scheduled cell on the unlicensed carrier, the carrier scheduling configuration message comprising a scheduling type identifier, a scheduling cell identifier, and Physical Downlink Shared Channel (PDSCH) starting symbol position information of a scheduling cell, and the scheduling type identifier indicating an uplink and downlink semi-persistent self-scheduling, an uplink and downlink semi-persistent cross-carrier scheduling, or a dynamic scheduling; and sending, by the base station, Radio Resource Control (RRC) signaling to user equipment that carries the carrier scheduling configuration message. Scheduling flexibility on an unlicensed carrier and throughput of communication systems can be improved by implementing the present disclosure.
