Sidelink Resource Reservation in DRX Patterns

The patent applies preliminary action by having the scheduling UE determine the DRX pattern of the scheduled UE before allocating sidelink resources. The scheduling UE proactively identifies active and inactive durations and plans resource allocations accordingly, preventing interference before it occurs. This is evident in the method where the scheduling UE receives indication of the DRX pattern and determines resource allocations based on active durations only.

The patent implements feedback mechanisms where UEs exchange DRX pattern information and resource allocation details. The scheduled UE provides feedback about its DRX pattern to the scheduling UE, enabling coordinated resource allocation. This feedback loop ensures that resource reservations align with the receiving UE's active durations, reducing conflicts while maintaining high resource utilization.

The patent introduces the scheduling UE as an intermediary that coordinates transmissions between UEs. The scheduling UE receives DRX pattern information from the scheduled UE and acts as a mediator to allocate resources during appropriate active durations. This intermediary function enables efficient scheduling that reduces latency by充分利用 available active periods while maintaining reliability through coordinated resource allocation.

The patent applies dynamics by enabling flexible and adaptive resource allocation that responds to varying DRX patterns. The scheduling UE dynamically adjusts resource reservations based on the scheduled UE's active durations, which may change over time. This dynamic approach allows the system to optimize for both low latency and high reliability by adapting to real-time DRX configurations.

The patent implements universality by designing a resource allocation mechanism that works across multiple UEs with different DRX patterns. The scheduling UE's ability to receive and process DRX pattern information from any scheduled UE, and allocate resources accordingly, creates a universal solution that handles diverse scenarios. This multi-functional approach maintains network efficiency while managing coordination complexity through a standardized procedure.

The patent applies self-service by enabling UEs to autonomously determine and report their own DRX patterns to the scheduling UE. Each UE independently provides its DRX configuration information, eliminating the need for complex centralized coordination. The scheduling UE then uses this self-provided information to allocate resources, reducing overall system complexity while maintaining efficient multi-UE operation.
