Overview
The present invention is a method and a system for dynamically switching transmission modes to increase reliability in unlicensed controlled environments (UCE). The system includes a user equipment (UE) to execute the method. When a next generation Node B (gNB) cannot successfully receive or decode data transmitted by the UE, the UE will receive a dynamic grant (DG) signal transmitted by the gNB. Therefore, when the UE can receive the DG signal, the UE will start a configured grant (CG) timer and count a CG counter, and the UE will calculate a CG weight. The UE further determines communication quality between the UE and the gNB according to the CG weight. When the CG weight is greater than a CG threshold, the UE determines communication quality is bad, and the UE will switch to a CG transmission mode to increase reliability for transmitting the data. Therefore, spectrum usage efficiency in the UCE can be improved.Category
