Abstract: This article introduces a novel approach to enhance Quality of Service in IEEE 802.11be Multi-Link Operation networks through coordinated Multi-User Enhanced Distributed Channel Access timer management. Current implementations suffer from inefficiencies due to independent timer operation across multiple links, leading to uncontrolled client transmissions and collisions during link transitions. The proposed solution implements inter-link timer synchronization, ensuring that successful trigger-based transmissions on one link result in timer resets across all active links for a client. This coordination mechanism maintains consistent Access Point control over uplink transmissions regardless of which frequency band is active, significantly reducing collision probabilities, improving transmission predictability, and enhancing network resource utilization. Through detailed analysis of implementation requirements and operational flow, this article demonstrates how synchronized timer management addresses a critical gap in the current specification. The article offers substantial benefits for QoS-sensitive applications including reduced collisions, consistent transmission scheduling, efficient resource allocation, and improved performance predictability across all active links, particularly during frequency band transitions in dense deployment scenarios.
