Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing sidelink communication parameters, particularly in adjusting reporting intervals for measurement results, which affects the performance of User Equipments (UEs) in Vehicle-to-Everything (V2X) scenarios.
Innovation Solution
A method where a first device transmits a measurement configuration to a second device, including a measurement object, identity, reporting configuration, and quantity configuration, with the reporting configuration specifying a first report interval determined by the first device. This allows for efficient reporting of measurement results in sidelink communication.

Engineering Contradiction Analysis
1Productivity
If the reporting interval is fixed and predetermined, then the system operation is simple, but the communication efficiency cannot be optimized based on channel conditions
Solution Approach 1:
The reporting interval is transformed from a fixed predetermined value to a dynamic parameter that can be adjusted by the transmitting UE based on measured channel conditions (CBR, relative speed, channel state). This allows the system to optimize communication efficiency by adapting the reporting frequency to actual channel quality, while the UE autonomously manages the adjustment without requiring complex network coordination.
2Loss of information
If the reporting interval is extended to reduce signaling overhead, then the signaling overhead is reduced, but the measurement precision and timeliness of channel state information deteriorate
Solution Approach 1:
The reporting interval is changed as a controllable parameter based on measured channel conditions. When channel conditions are good (low CBR, stable relative speed, good channel state), the interval is extended to reduce signaling overhead. When channel conditions deteriorate, the interval is shortened to maintain measurement precision and timeliness of channel state information.
3Reliability
If the reporting interval is shortened to improve responsiveness to channel changes, then the measurement timeliness is improved, but the signaling overhead and power consumption increase
Solution Approach 1:
The reporting interval is dynamically adjusted based on measured channel conditions including CBR, relative speed, and channel state. When channel conditions are stable and good, the interval is extended to reduce power consumption and signaling overhead. When channel conditions change rapidly or deteriorate, the interval is shortened to maintain responsiveness, balancing reliability requirements with energy efficiency.
4Productivity
If autonomous parameter adjustment by UE is enabled to improve communication efficiency, then the communication efficiency is improved, but the device complexity and parameter management difficulty increase
Solution Approach 1:
The transmitting UE is empowered to autonomously measure channel conditions (CBR, relative speed, channel state) and independently adjust the reporting interval parameter without requiring network coordination or complex configuration management. This self-service approach improves communication efficiency by enabling rapid adaptation to channel changes while keeping the implementation relatively simple, as the UE uses its existing measurement capabilities for autonomous decision-making.
