The present disclosure describes a method including accessing a cell operating in an unlicensed spectrum and configuring at least one physical shared channel in the cell; indicating, by DCI, the number of slots scheduled for a current physical shared channel if the number of aggregated slots for the at least one physical shared channel configured by RRC signaling is greater than 1; and indicating, by the DCI, at least one piece of time-domain resource allocation information. The time-domain resource allocation information includes: an offset value between a slot where the physical shared channel is located and a slot where a physical downlink control channel is transmitted; a starting symbol position of the physical shared channel; length information of symbols of the physical shared channel; and a mapping type of the physical shared channel.
