CNN-Enabled Scheduling for Probabilistic Real-Time Guarantees in Industrial URLLC
This work addresses the need for improved interference coordination in multi-cell, multi-channel industrial wireless networks, offering incremental enhancements to existing scheduling methods.
The paper tackles the problem of ensuring packet-level communication quality in industrial URLLC networks by enhancing the LDP algorithm with a CNN-based dynamic priority prediction mechanism, resulting in SINR gains of up to 113%, 94%, and 49% over LDP in simulations.
Ensuring packet-level communication quality is vital for ultra-reliable, low-latency communications (URLLC) in large-scale industrial wireless networks. We enhance the Local Deadline Partition (LDP) algorithm by introducing a CNN-based dynamic priority prediction mechanism for improved interference coordination in multi-cell, multi-channel networks. Unlike LDP's static priorities, our approach uses a Convolutional Neural Network and graph coloring to adaptively assign link priorities based on real-time traffic, transmission opportunities, and network conditions. Assuming that first training phase is performed offline, our approach introduced minimal overhead, while enabling more efficient resource allocation, boosting network capacity, SINR, and schedulability. Simulation results show SINR gains of up to 113\%, 94\%, and 49\% over LDP across three network configurations, highlighting its effectiveness for complex URLLC scenarios.
