Sidelink Resource Selection Using UE Sensing and Coordination

The patent extracts only the essential resource coordination information from full coordination messages by identifying and prioritizing critical parameters (such as resource availability, interference levels, and transmission power) while omitting redundant data. This selective extraction reduces message overhead while preserving the core functionality of collision avoidance through resource coordination.

The patent implements partial resource coordination where UEs exchange coordination messages only for a subset of resources or under specific conditions (e.g., when collision risk is detected or during initial resource allocation) rather than continuously coordinating all resources. This partial action approach maintains collision-free operation for critical resources while reducing overall signaling overhead.

The patent applies local quality by enabling resource coordination only in specific geographic areas or service zones where collision risk is high or where UEs are densely deployed. UEs in different local areas can operate independently with minimal coordination overhead, while maintaining collision-free operation locally. This spatially selective coordination reduces overall channel congestion while preserving reliability where needed.

The patent implements conditional resource coordination where UEs exchange coordination messages only when specific triggers are detected, such as high collision probability, entry into a coordinated service zone, or resource reselection events. This event-driven partial coordination maintains collision avoidance effectiveness while minimizing unnecessary signaling that would contribute to channel congestion.
