The invention provides an uplink scheduling method based on a dynamic frame structure, a downlink scheduling device, and a base station. Each frame structure employed at an unauthorized frequency band just comprises uplink subframes and downlink subframes, and the subframes of the same type in each frame structure are set continuously. The method comprises the steps: judging whether the frame structure employed at the current unauthorized frequency band needs to be reconfigured or not; determining the to-be-scheduled uplink subframe at each downlink subframe according to the currently employed frame structure when the frame structure employed at the current unauthorized frequency band does not need to be configured; determining the to-be-scheduled uplink subframe, at each downlink subrame, in a last wireless frame before a reconfiguration time point according to a first frame structure employed before the reconfiguration time point and a second frame structure to be used when the frame structure employed at the current unauthorized frequency band needs to be reconfigured; and transmitting a scheduling instruction for the t-be-scheduled uplink subframe at each downlink subframe.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink scheduling method based on a dynamic frame structure in an unlicensed frequency band, an uplink scheduling device based on a dynamic frame structure in an unlicensed frequency band, and a base station. Background technique [0002] With the rapid increase of communication traffic, the 3GPP authorized spectrum is increasingly insufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP proposes the concept of LAA (LTE Assisted Access, LTE Assisted Access), which is used to use unlicensed spectrum with the help of LTE (Long Term Evolution, Long Term Evolution) licensed spectrum. In order to make the LTE system coexist harmoniously with different systems such as Wi-Fi on the unlicensed frequency band, 3GPP proposed the LBT (Listen Before Talk, Listen Before Talk) mechanism to ensure that the unlicen...
