Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a symbol scheduling strategy for deep joint source-channel coding (DeepJSCC) over time-varying MIMO channels. In high-mobility scenarios, channel state information (CSI) becomes outdated over time (Outdated CSI), causing severe inter-stream interference that significantly degrades image reconstruction. To mitigate this, we focus on image entropy. High-entropy texture regions are sensitive to interference, whereas interference artifacts in low-entropy background regions are less perceptually noticeable. Furthermore, we conjecture that simultaneously transmitting similar low-entropy regions multiplexes similar symbols, suppressing the severe degradation of interference. The proposed strategy allocates high-entropy regions to earlier frame segments with highly accurate CSI, and low-entropy regions to later segments with aged CSI. Simulation results demonstrate that this approach effectively preserves key visual features and improves overall decoding performance under rapid channel variations.
