Mixed-Service Grant Prioritization for URLLC MAC PDU Handling

The patent segments the grant handling process into distinct phases: identification of overlapping grants, determination of priority based on service type, and selective construction of MAC PDU. This segmentation allows the system to evaluate each grant independently and apply priority rules to ensure URLLC traffic receives appropriate treatment while still utilizing eMBB resources when no conflicts exist.

The patent implements preliminary action by establishing a priority determination mechanism before grant execution. The UE identifies overlapping grants and determines their priorities based on service type (URLLC vs. eMBB) before constructing MAC PDUs. This preliminary prioritization ensures that when conflicts occur, URLLC traffic is automatically favored, maintaining QoS requirements while still allowing eMBB grants to be utilized when no overlaps exist.

The patent applies local quality by implementing priority handling specifically at the point of grant overlap identification. Rather than complicating the entire grant processing pipeline, the solution introduces priority determination only where needed - when multiple grants overlap in time. This localized approach maintains simplicity for non-overlapping grants while providing sophisticated QoS management only when conflicts occur.

The patent introduces dynamics by making the grant handling process adaptive based on overlap detection. The UE dynamically adjusts its behavior: when no overlaps are detected, standard grant processing applies; when overlaps are detected, the system activates priority determination and selective MAC PDU construction. This dynamic approach maintains simplicity for the common case while providing sophisticated handling only when necessary.
