Abstract

Disclosed are a method, base station and terminal for dynamic uplink configuration in a wireless communication system, the method comprising: determining reconfiguration information comprising a reconfiguration point of time, so as 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 comprising the second uplink and downlink subframe configuration. The method, base station and terminal effectively achieve at least one of the following results: ensuring resource utilization, addressing timing sequence conflicts, coordinating processes, ensuring user throughput and effectively reducing transmission delay during TDD uplink and downlink reconfiguration.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method for dynamic uplink configuration in a wireless communication system, a base station and a communication terminal. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] In the Time Division Duplex (TDD) wireless communication system supported by the Long Term Evolution (LTE) technology, it can provide 7 different asymmetric uplink and downlink configurations. These uplink and downlink configurations can provide 40%-90% of downlink subframes, and have flexible service adaptation characteristics. [0004] For seven uplink and downlink configurations, the current standard specifies the uplink and downlink hybrid automatic retransmission (HARQ) timing under different configurations, and the number of uplink and downlink HARQ concurrent processes und...
