Sidelink Configured Grant Deactivation Upon Failure Detection

The patent implements a feedback mechanism where the wireless device monitors sidelink transmission quality and provides feedback information to the network about transmission problems. This feedback enables the network to dynamically adjust grant configurations, deactivating grants when transmission issues are detected and reactivating them when conditions improve, thereby resolving the contradiction between maintaining communication efficiency and avoiding resource waste.

The patent introduces dynamic grant management where configured grants are not static but can be activated, deactivated, or modified based on real-time transmission conditions. The network dynamically adjusts the grant state based on feedback from the wireless device, allowing the system to adapt between continuous operation mode and resource-saving mode, thus resolving the efficiency versus waste contradiction.

The patent applies preliminary action by pre-configuring multiple grant parameters and establishing clear deactivation criteria before transmission problems occur. When issues are detected, the system can quickly deactivate grants using pre-established procedures rather than performing complex real-time decisions, thus reducing the reliability impact of reconfiguration while still achieving resource savings.

The feedback mechanism provides the network with accurate information about transmission quality, enabling informed decisions about when to deactivate grants. This feedback loop ensures that deactivation only occurs when truly necessary, avoiding unnecessary reconfigurations that would harm reliability, while still achieving resource waste reduction when transmission problems are confirmed.

The patent segments the grant management function into distinct components: grant configuration, transmission monitoring, feedback generation, and grant deactivation. This segmentation allows each component to be implemented independently with clear responsibilities, improving resource management efficiency while keeping the overall system complexity manageable through modular design.

The wireless device performs self-service by autonomously monitoring its own transmission quality and generating feedback information without requiring constant network intervention. This self-service capability simplifies the control mechanism by empowering the device to manage its own grants based on pre-established criteria, improving resource management efficiency while avoiding the complexity of continuous network control.
