Abstract

Disclosed are a data transmission method and device, and a frame structure of a time division duplex (TDD) system. The method comprises: classifying wireless frames of a TDD system into fixed downlink subframes, special subframes, fixed uplink subframes, and dynamic subframes according to a predetermined rule (S302), the dynamic subframes being used for transmitting uplink data or downlink data, or for canceling data transmission; performing data transmission on the wireless frames after the classification operation (S304). The present invention achieves the effect of improving data transmission efficiency.
