CLI Measurement Reporting for 5G Uplink Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in effectively measuring and reporting cross-link interference (CLI) in advanced mobile communication technologies like 5G and 6G, which are essential for optimizing network performance and supporting diverse services such as eMBB, URLLC, and mMTC.
Innovation Solution
A method and apparatus for a user equipment (UE) to receive configuration information about CLI from a base station (BS), measure the CLI quantity, and transmit the measured value via a physical uplink shared channel (PUSCH) using a medium access control (MAC) control element (CE), enabling effective CLI reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CLI measurement and reporting mechanisms are implemented in 5G wireless communication systems, then network performance optimization is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments the CLI measurement process into distinct components: configuration reception from base station, actual CLI measurement on uplink resources, and structured reporting through MAC CE or RRC messages. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining measurement reliability.
Solution Approach 2:
The patent implements preliminary configuration where the base station provides CLI measurement configuration information before actual measurements are performed. This includes pre-defining measurement resources, reporting formats, and thresholds, which simplifies the subsequent measurement and reporting processes by establishing clear protocols in advance.
2Measurement precision
If CLI measurement resources are allocated in uplink slots, then cross-link interference detection capability is improved, but uplink resource availability for data transmission is reduced
Solution Approach 1:
The patent employs dynamic resource allocation where CLI measurement resources are allocated flexibly based on network conditions, service requirements, and interference levels. The base station can dynamically adjust the frequency, timing, and quantity of CLI measurement opportunities to balance measurement accuracy with data transmission efficiency, rather than using fixed resource allocation.
Solution Approach 2:
The patent implements partial measurement action by selecting specific uplink slots for CLI measurement rather than continuously monitoring all uplink resources. The system performs measurements only when necessary based on configured triggers, events, or periodic intervals, thereby reducing the impact on uplink data transmission while maintaining sufficient CLI detection capability.
3Adaptability or versatility
If multiple CLI measurement configurations are supported for different services, then service adaptability is improved, but configuration complexity and processing overhead increase
Solution Approach 1:
The patent designs a universal CLI measurement framework that can accommodate multiple services (eMBB, URLLC, mMTC) through a common configuration structure. The base station provides service-specific parameters within a standardized configuration template, allowing the same measurement mechanism to serve different services without requiring separate dedicated systems, thus reducing overall complexity while maintaining service adaptability.
Solution Approach 2:
The patent applies local quality by configuring CLI measurement parameters specifically tailored to each service's requirements. Different services receive customized measurement configurations (e.g., measurement frequency, resource allocation, reporting thresholds) based on their unique performance needs, allowing optimal measurement performance for each service while managing complexity through localized rather than global customization.
