Abstract

The present invention provides an uplink scheduling method based on a dynamic frame structure on an unlicensed frequency band, an uplink scheduling device and a base station, wherein each frame structure adopted on the unlicensed frequency band only includes uplink subframes and downlink subframes , and the subframes of the same type included in each frame structure are set continuously, the uplink scheduling method includes: judging whether the frame structure currently used on the unlicensed frequency band needs to be reconfigured; When configuring, determine the uplink subframes to be scheduled on each downlink subframe according to the currently used frame structure; Two-frame structure, determining the uplink subframe to be scheduled on each downlink subframe in the last radio frame before the reconfiguration time point; sending the uplink subframe to be scheduled on each downlink subframe scheduling instructions.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to an uplink scheduling method based on a dynamic frame structure on an unlicensed frequency band, an uplink scheduling device based on a dynamic frame structure on an unlicensed frequency band, and a base station. Background technique [0002] With the rapid increase in communication traffic, the 3GPP authorized spectrum seems increasingly insufficient to provide higher network capacity. In order to further improve the utilization of spectrum resources, 3GPP proposed the concept of LAA (LTE Assisted Access), which is used to use unlicensed spectrum with the help of LTE (Long Term Evolution) licensed spectrum. In order to enable the LTE system to coexist harmoniously with different systems such as Wi-Fi on unlicensed frequency bands, 3GPP has proposed the LBT (Listen Before Talk, listen before talk) mechanism to ensure that the unlicensed frequency band is used by comp...
