Patent ID: 10243708

Abstract:
A method performing dynamic downlink configuration in a wireless communications system, a base station, and a terminal. The method includes: setting a reconfiguration point to enable a first uplink and downlink subframe configuration to be adopted in a first configuration period before the reconfiguration point and enable a second uplink and downlink subframe configuration to be adopted in a second configuration period after the reconfiguration point; and adopting a reference uplink/downlink subframe configuration adapted for an uplink subframe intersection of respective uplink/downlink subframe configurations for a time sequence of a downlink HARQ process during the predetermined change of the dynamical downlink configuration. The resource utilization rate during the TDD uplink and downlink configuration and reconfiguration can be effectively ensured, the time sequence conflict can be solved, the process can be coordinated, the user throughput can be ensured, and the transmission delay can be reduced as far as possible.
