Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connected-vehicle radio-frequency environment is spectrum-limited and bandwidth-limited, leading to increased latency and reduced user experience due to high-data rate service demands in congested areas, particularly in public transportation and traffic congestion scenarios.
Innovation Solution
User equipment (UE) utilizes sensors to gather environmental and UE conditions, adjusting communication directionality, transmit power, and transmit frequency to optimize resource allocation for efficient communication, reducing redundancy and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mobile devices request high-data rate services in congested areas, then data service coverage is improved, but network latency increases and user experience degrades
Solution Approach 1:
The patent segments communication resources by direction, dividing the communication space into multiple directional sectors. Each sector can independently manage its communication resources, allowing simultaneous high-data rate services in different directions without mutual interference, thus reducing network latency while maintaining service coverage.
Solution Approach 2:
The patent implements dynamic resource allocation where communication resources are adjusted in real-time based on environmental conditions and UE states. The system dynamically switches between different communication modes (e.g., connected mode, idle mode, discontinuous reception) and adjusts transmit power and resource allocation according to current traffic conditions, reducing latency during high-demand periods while maintaining coverage.
2Reliability
If communication resources are increased to meet high-data rate demands, then service quality is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts communication resources based on real-time conditions. When high-data rate services are requested, the system activates connected mode with appropriate resource allocation. When traffic demand decreases, the system transitions to idle mode or discontinuous reception, significantly reducing energy consumption while maintaining service quality when needed.
Solution Approach 2:
The patent changes communication parameters such as transmit power, resource block allocation, and reception modes based on environmental conditions and UE state. By adjusting these parameters dynamically, the system maintains high service quality when required while minimizing energy consumption during low-activity periods.
3Reliability
If transmit power is increased to improve communication reliability, then connection stability is improved, but interference to other users increases
Solution Approach 1:
The patent divides the communication spectrum into directional sectors, allowing each sector to transmit at higher power levels targeted at specific directions. This segmentation enables improved connection stability in each direction while limiting interference to other directional sectors, as the high-power transmissions are spatially confined.
Solution Approach 2:
The system applies different transmit power levels to different directional sectors based on local conditions. Areas with poor signal quality or high demand receive higher localized power transmission, while areas with good signal quality use lower power, thereby maintaining connection stability where needed while minimizing overall interference.
