Furthermore, to achieve a higher level of sparsity, we propose using an entropy parameterization technique for the frequency domain, specifically for DCT coefficients of the feature-grid.

Compared to regular HARQ, the DA2SGMM reduces the maximum transmission latency by more than 72. 4 %, while maintaining more than 75 % of the throughput in the no-blockage scenario.

Furthermore, we demonstrate that the proposed protocol clearly outperforms the classical proactive HARQ in all scenarios when taking a processing delay reduction due to the less complex prediction approach into account, achieving an energy efficiency gain in the range of 11% up to 15% for very stringent latency budgets of 1 ms at $10^{-2}$ BLER and from 4% up to 7. 5% for less stringent latency budgets of 2 ms at $10^{-3}$ BLER.
