Terminal Cross-Link Interference Measurement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in effectively controlling and reporting cross-link interference (CLI) measurements between terminals in different cells, leading to inefficient energy consumption and communication interference, particularly due to the lack of mitigation techniques for dynamic duplexing operations.
Innovation Solution
A method and apparatus for a terminal to receive and perform CLI measurements based on a configuration from a network device, which includes SRS resource configurations associated with cell identities or indices, allowing for controlled execution and reporting of measurements to prevent interference, using signal quality thresholds to determine validity and trigger measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CLI measurements are performed continuously between terminals in different cells, then interference detection capability is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic CLI measurement control where the network device configures measurement parameters including activation conditions and reporting thresholds. The terminal performs measurements selectively based on configured criteria rather than continuously, allowing the system to adapt measurement activity to actual interference conditions and reduce unnecessary energy consumption while maintaining reliable interference detection capability.
2Speed
If CLI measurements are performed frequently to detect interference quickly, then interference detection speed is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic CLI measurement opportunities configured by the network device, where measurements are performed at specific intervals or triggered events rather than continuously. The measurement configuration includes periodicity parameters and activation conditions that allow the system to maintain interference detection capability while reducing measurement frequency to acceptable levels that conserve terminal energy.
3Measurement precision
If detailed CLI measurement configuration is provided for all SRS resources, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the CLI measurement configuration by associating specific SRS resource configurations with particular cell identities or SRS indexes. Instead of providing comprehensive configuration for all possible SRS resources, the network device provides targeted configurations only for relevant resources, reducing configuration complexity while maintaining measurement precision for the configured resources through detailed parameters.
4Reliability
If CLI measurements are reported for all measured SRS resources, then interference monitoring coverage is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and reports only the essential CLI measurement results that are most relevant for interference management. The reporting mechanism is configured to selectively report measurements based on thresholds, activation conditions, or specific resource configurations, rather than reporting all measured values. This reduces signaling overhead by filtering out redundant information while maintaining adequate interference monitoring coverage through strategic selection of reported measurements.

AI summary
A method for controlling measurement includes that: the terminal receives a cross-link interference (CLI) measurement configuration from a network device, where the CLI measurement configuration includes at least one sounding reference signal (SRS) resource configuration, each of the at least one SRS resource configuration being associated with at least one of a cell identity or an SRS index; and the terminal performs a CLI measurement according to the CLI measurement configuration, where the CLI measurement refers to that the terminal measures an SRS of another terminal. A terminal and a non-transitory computer-readable storage medium are also provided.
