Sidelink Transmission Priority Management for LTE NR Coexistence

The patent applies parameter changes by dynamically adjusting transmission power levels and timing parameters based on the priority of different RAT transmissions. When both LTE and NR sidelink transmissions are scheduled, the device modifies power parameters and timing parameters to ensure high-priority transmissions receive sufficient power while maintaining synchronization, thereby resolving the contradiction between communication capacity and transmission reliability.

The patent implements dynamics by introducing dynamic power management mechanisms that adaptively adjust transmission power based on real-time conditions. The device dynamically determines power allocation for LTE and NR sidelink transmissions using priority-based power control, ensuring that service coverage is maintained while avoiding the complexity of static high-power configurations. This allows the system to optimize power distribution according to actual transmission needs.

The patent applies segmentation by dividing the synchronization requirement into different levels: frame-level synchronization is maintained for reliability, while sub-frame and symbol-level flexibility is preserved for resource allocation. This segmented approach allows the device to meet synchronization requirements for reliable transmission while maintaining the flexibility needed for efficient resource allocation across different RATs.
