Pedestrian UE V2X Resource Selection via Partial Sensing

The patent applies partial sensing instead of full sensing by monitoring only a subset of resource pools (e.g., one resource pool out of multiple configured resource pools) for V2X transmission resource selection. This partial action approach maintains adequate resource selection reliability while significantly reducing the power consumption associated with continuous full sensing operations, directly resolving the contradiction between reliability and energy consumption.

The patent enables the pedestrian UE to operate in multiple resource pools with different sensing requirements. By configuring multiple resource pools where some require full sensing and others require partial sensing or random selection, the system achieves multi-functionality that adapts to different service requirements and battery states, balancing reliability and power consumption across diverse operating scenarios.

The patent applies different resource selection methods (random selection, partial sensing, full sensing) to different resource pools based on their specific characteristics and service requirements. By assigning random selection to resource pools with lower reliability requirements while using sensing-based methods for critical resources, the system locally optimizes the balance between power consumption and interference reduction for each resource pool.

The patent enables dynamic switching between random selection and sensing-based resource selection methods based on changing conditions such as battery status, traffic load, and channel conditions. This dynamic adaptation allows the pedestrian UE to use random selection when power is critical and switching to sensing-based methods when interference management becomes priority, resolving the contradiction flexibly.
