Time Window Based Sidelink Full-Duplex Signaling

The patent applies preliminary action by pre-configuring full-duplex transmission parameters (such as transmit power, resource allocation, beamforming vectors) during initial connection setup or periodic updates, rather than dynamically signaling them for each transmission. This allows the parameters to be reused across multiple transmissions within the configured time window, significantly reducing signaling overhead while maintaining communication flexibility through periodic reconfiguration.

The patent makes control signaling universal by designing a configuration framework that can serve multiple purposes: initial connection setup, periodic parameter updates, and adaptive reconfiguration based on channel conditions. The same configuration mechanism handles both full-duplex and half-duplex modes, and can be applied across different traffic types and service requirements, reducing the need for dedicated dynamic signaling.

The patent applies segmentation by dividing time resources into distinct full-duplex and half-duplex time windows or slots, allowing different resource allocation strategies to be applied in each segment. During full-duplex segments, both transmit and receive operations can occur simultaneously with dedicated resource pools, while half-duplex segments use traditional allocation methods, optimizing overall system efficiency without requiring complete redesign of resource management.

The patent introduces dynamics by enabling flexible switching between full-duplex and half-duplex modes based on traffic conditions, channel quality, and service requirements. The system can dynamically adjust the proportion of full-duplex versus half-duplex time resources, and adaptively reconfigure parameters within each mode, allowing resource allocation complexity to scale with performance requirements rather than being fixed.
