Engineering Contradiction Analysis
1Reliability
If continuous partial sensing is performed for autonomous resource selection in sidelink communication, then resource allocation reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements discontinuous sensing by performing partial sensing only during periodic active periods rather than continuously. The UE configures sensing parameters including sensing window length, sensing periodicity, and active period timing to monitor resources at intervals, thereby maintaining resource allocation reliability while significantly reducing power consumption during V2X communication operations
Solution Approach 2:
The patent introduces adaptive sensing parameter configuration where the UE dynamically adjusts sensing behavior based on communication conditions. The sensing parameters (window length, periodicity, active period timing) are configured to adapt between different operational states, allowing the system to optimize the balance between sensing thoroughness and power consumption based on current V2X communication requirements
2Use of energy by moving object
If sensing parameters are configured for discontinuous operation, then power consumption is reduced, but resource selection accuracy may deteriorate
Solution Approach 1:
The patent employs configurable sensing parameters including sensing window length, sensing periodicity, and active period timing that can be adjusted to optimize performance. By changing these parameters, the system adapts the sensing granularity and coverage to match communication requirements, ensuring sufficient resource selection accuracy while maintaining reduced power consumption through discontinuous operation modes
