Configured Grant Signaling for Dynamic BWP and Sub-Band Allocation

The patent segments the BWP configuration process into distinct phases: activation phase where DCI formats indicate BWP activation, validation phase where the wireless device checks configuration validity, and release phase where BWPs are systematically deactivated. This segmentation manages complexity by breaking down the dynamic configuration process into manageable, standardized steps while maintaining high resource allocation flexibility.

The patent implements preliminary validation checks before BWP activation, where the wireless device validates DCI format compliance and configuration parameters beforehand. This preliminary action prevents invalid configurations from proceeding, reducing system complexity by filtering out errors early while maintaining the ability to dynamically allocate resources efficiently.

The patent implements feedback mechanisms where the wireless device validates received DCI configurations against predefined criteria and provides implicit feedback through successful activation or explicit feedback through validation failure reporting. This feedback loop enables the system to manage multiple BWPs and sub-bands adaptively while maintaining control over management complexity through automated validation.

The wireless device performs self-validation of BWP configurations received via DCI, checking whether the configurations meet specified criteria before activation. This self-service approach reduces signaling overhead by eliminating the need for extensive network-side validation of each BWP configuration, while still ensuring proper resource allocation capability across multiple BWPs and sub-bands.

The patent performs preliminary validation of BWP configurations before activation, checking DCI format compliance and parameter validity in advance. This preliminary action enables fast switching by ensuring that validated configurations are ready for immediate activation without requiring extensive validation during the switching process itself, thus reducing latency while managing validation overhead.

The patent changes validation parameters dynamically based on the DCI format received, adjusting the strictness and type of validation performed according to the specific configuration being activated. This adaptive parameter changing optimizes the balance between fast switching and thorough validation by applying appropriate validation levels only when necessary, reducing overall validation overhead while maintaining transmission speed.
