Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurement resources are configured for each measurement type (CLI, SI, wireless sensing), then measurement precision is ensured, but device complexity and signaling overhead increase
Solution Approach 1:
The patent applies universality by enabling a single measurement resource to serve multiple measurement types (CLI, SI, and wireless sensing) through a common measurement object. The measurement resource is configured with a measurement type indicator that can take different values to specify the intended measurement type, allowing one resource to perform multiple functions without sacrificing measurement precision.
2Measurement precision
If separate measurement resources are configured for each measurement type, then measurement accuracy is maintained, but spectral efficiency decreases
Solution Approach 1:
The measurement resource is designed to be universal, supporting multiple measurement types through a single configuration. The measurement type indicator allows the same physical resource to be logically assigned to different measurement purposes, thereby improving spectral efficiency by reducing the total number of resources needed while maintaining measurement accuracy through proper signal processing for each measurement type.
Solution Approach 2:
The patent merges the configuration of multiple measurement resources into a single unified measurement resource. By combining CLI, SI, and wireless sensing measurements into one shared resource with appropriate multiplexing, the system reduces resource utilization overhead and improves spectral efficiency while preserving the accuracy required for each individual measurement type through dedicated processing paths.
3Reliability
If multiple measurement configurations are used, then measurement reliability is ensured, but signaling overhead increases
Solution Approach 1:
The universal measurement resource eliminates the need for multiple separate configurations by using a single configuration that can accommodate different measurement types through the measurement type indicator. This reduces signaling overhead significantly while maintaining measurement reliability, as the same resource can be reliably used for CLI, SI, and wireless sensing measurements with proper parameter configuration.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement configuration that is associated with a common measurement object or a common resource pool for at least two of cross-link interference (CLI) measurements, self-interference (SI) measurements, or wireless sensing measurements. The UE may perform, based at least in part on the measurement configuration, one or more measurements that include at least one of a CLI measurement, an SI measurement, or a wireless sensing measurement. The UE may transmit, based at least in part on the measurement configuration, a measurement report indicating at least one measurement of the one or more measurements. Numerous other aspects are described.
