In Network Slicing (NS), the hard RAN slicing interactions with the physical transmission environment have been explored predominantly, with limited consideration given to the interaction between slicing and existing transmission protocols. To address this gap, we propose a novel cross-slice re-transmission protocol integrated with NS, aiming to maximize throughput while ensuring latency constraints. Our protocol introduces adaptive re-transmission parameters, cross-slicing retransmission, and flexible duplexing mode switching. We model the problem as a bi-level optimization framework and propose a nested Hungarian-based reinforcement learning algorithm for optimization. Extensive experiments demonstrate the proposed protocol and algorithm's superiority in throughput and latency performance. Additionally, we investigate the impact of user count on throughput, providing configuration recommendations for optimal performance.
