Abstract: A method, base station, and terminal for dynamic uplink configuration in a wireless communication system, the method including: determining reconfiguration information including a reconfiguration point of time, to employ first uplink and downlink subframe configuration in the first configuration period before the reconfiguration point of time, and to employ second uplink and downlink subframe configuration in a second configuration period after the reconfiguration point of time; and in the last transmission period before the reconfiguration point of time, employing an uplink scheduling timing sequence of a reference uplink and downlink subframe configuration according to an uplink data timing sequence, the reference uplink and downlink subframe configuration including the second uplink and downlink subframe configuration. The method, base station, and terminal efficiently achieve at least one of: ensuring resource utilization, addressing timing sequence conflicts, coordinating processes, ensuring user throughput, or reducing transmission delay during TDD uplink and downlink reconfiguration.
