Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in effectively measuring and managing cross-link interference (CLI) between network nodes and user equipment, which can impact communication quality and efficiency.
Innovation Solution
Implementing methods and apparatuses for UE and network nodes to receive and transmit CLI measurement reports and configurations, utilizing a CLI reference resource defined by an offset relative to a reporting resource, to manage and mitigate CLI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CLI measurement is performed on resources immediately preceding the reporting resource, then measurement accuracy is improved, but processing time becomes insufficient leading to reporting errors
Solution Approach 1:
The patent introduces a reference resource that occurs before the measurement resource, allowing the UE to perform preliminary actions such as receiving configuration information and preparing measurement capabilities. This preliminary action ensures that when the measurement resource arrives, the UE is already prepared and has sufficient processing time, resolving the contradiction between measurement accuracy and processing time sufficiency.
Solution Approach 2:
The patent segments the CLI measurement process into distinct phases: a reference resource phase for configuration and capability indication, and a measurement resource phase for actual measurement. This segmentation allows each phase to be optimized independently - the reference resource provides advance preparation time while the measurement resource ensures accurate timing for actual measurement, thus resolving the time-accuracy contradiction.
2Productivity
If measurement resources are configured without considering UE capabilities, then resource utilization efficiency is improved, but measurement accuracy deteriorates due to insufficient processing time
Solution Approach 1:
The patent makes the measurement resource configuration dynamic by introducing a capability indication mechanism. The network configures reference resources and measurement resources based on the UE's indicated capabilities regarding processing time and measurement accuracy requirements. This dynamic adaptation allows the system to optimize resource utilization while ensuring each UE receives configurations matched to its specific capabilities, resolving the contradiction between efficiency and accuracy.
3Speed
If reporting is configured without reference resource timing, then reporting speed is improved, but reporting reliability deteriorates due to timing misalignment
Solution Approach 1:
The reference resource serves as a preliminary action that establishes the timing framework before actual measurement and reporting occur. By indicating the timing relationship between the reference resource, measurement resource, and reporting resource in advance, the UE can prepare measurement data with proper timing alignment, ensuring both fast reporting and high reliability through pre-synchronized timing relationships.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a cross-link interference (CLI) measurement reporting configuration indicating a reporting resource for reporting of a CLI measurement regarding an aggressor network node or an aggressor UE associated with the aggressor network node. The UE may transmit a CLI measurement report on the reporting resource, the CLI measurement report indicating the CLI measurement on a measurement resource that occurs no later than a CLI reference resource that is defined by an offset relative to the reporting resource. Numerous other aspects are described.
