  • Patent number: 11044742
    Abstract: The present disclosure provides an uplink scheduling method in an unlicensed frequency band based on a dynamic frame structure, an uplink scheduling device and a base station. Each frame structure includes uplink and downlink subframes, and same type of a subframe continuity settings, the method includes: determining whether a currently used frame structure in an unlicensed frequency band needs to be reconfigured; when reconfiguration is not required, determining an uplink subframe to be scheduled on each downlink subframe according to the currently used frame structure; when reconfiguration is required, determining an uplink subframe to be scheduled on each downlink subframe in a last radio frame before a reconfiguration time point according to a first frame structure used before the reconfiguration time point and a second frame structure to be used; transmitting a scheduling instruction for the uplink subframe to be scheduled on each downlink subframe.

  • Publication number: 20190173624
    Abstract: A downlink Hybrid Automatic Repeat Request (HARQ) feedback method is provided, and includes: determining whether a currently used frame structure needs to be reconfigured; determining an uplink subframe for implementing a downlink HARQ feedback corresponds to each downlink subframe according to the currently used frame structure, when no reconfiguration is needed; determining an uplink subframe for implementing the downlink HARQ feedback corresponds to each downlink subframe in a last radio frame before the reconfiguration time point, when the reconfiguration is needed, according to a first frame structure used before a reconfiguration time point and a second frame structure to be used; determining an uplink subframe for implementing the downlink HARQ feedback corresponds to each downlink subframe in a last radio frame before the reconfiguration time point; when receiving downlink data sent by a base station on any downlink subframe, sending a HARQ feedback message for the downlink data.
