Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CBR measurement is performed on both LTE and NR sidelinks simultaneously, then measurement completeness is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent implements dynamic measurement execution by determining whether to perform CBR measurements on LTE and/or NR sidelinks based on current service requirements and configuration. The measurement execution is flexible and adaptive, allowing the system to switch between performing both measurements, only one measurement, or neither measurement based on real-time conditions, thereby reducing device complexity while maintaining measurement completeness when needed.
Solution Approach 2:
The patent changes the parameter of measurement execution state from fixed to variable. By introducing a determination step that evaluates service requirements and configuration parameters before executing measurements, the system dynamically adjusts whether to perform CBR measurements on LTE and/or NR sidelinks. This parameter change allows the system to optimize between measurement completeness and device complexity by only performing measurements when actually required.
2Reliability
If CBR measurement is performed on both LTE and NR sidelinks, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic measurement execution by determining whether to perform CBR measurements on LTE and/or NR sidelinks based on current service requirements and configuration. The measurement execution is flexible and adaptive, allowing the system to switch between performing both measurements, only one measurement, or neither measurement based on real-time conditions, thereby reducing device complexity while maintaining measurement completeness when needed.
Solution Approach 2:
The system performs self-determination regarding whether CBR measurements are needed by evaluating service requirements and configuration parameters. This self-service mechanism allows the device to autonomously decide when measurements are necessary for maintaining communication reliability, avoiding unnecessary measurements that would consume power, while ensuring measurements are performed when required for reliable operation.
3Measurement precision
If separate CBR measurement configurations are used for LTE and NR sidelinks, then measurement accuracy is improved, but system complexity increases
Solution Approach 1:
The patent introduces a universal co-existence CBR measurement configuration that can apply to both LTE and NR sidelinks. This unified configuration approach allows the system to maintain separate measurement requirements for different technologies while using a single configuration framework, thereby reducing configuration management complexity while preserving measurement accuracy through technology-specific measurement execution.
4Reliability
If power is allocated to both LTE and NR sidelinks simultaneously, then communication performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power allocation by determining power distribution based on service requirements and configuration. Instead of fixed power allocation to both sidelinks, the system dynamically adjusts power distribution, allocating power to LTE and/or NR sidelinks only when measurements and communications are actually required, thereby maintaining communication performance while reducing overall power consumption.
Solution Approach 2:
The patent changes the power allocation parameter from fixed to variable based on service requirements. By introducing dynamic determination of whether to perform measurements and allocate power to each sidelink, the system optimizes power distribution, ensuring adequate power for communication performance when needed while minimizing power consumption when measurements or communications are not required.
