Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technology, intra-UE interference poses a significant challenge due to imperfections in radio frequency devices, where signals transmitted by User Equipment (UE) interfere with received signals, affecting communication performance, and there is a need to acquire relevant information about this interference to improve performance.
Innovation Solution
A capability information reporting method and system that acquire a predicted frequency range of intra-UE interference and receive intra-UE interference suppression capability information from the UE, allowing for effective interference management by transmitting this information to network side devices, which can then perform interference avoiding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intra-UE interference suppression capability information is reported for the entire frequency range, then the network can comprehensively manage interference, but the signaling overhead increases
Solution Approach 1:
The frequency range is divided into multiple sub-bands, and the UE reports intra-UE interference suppression capability information separately for each sub-band rather than for the entire frequency range. This segmentation approach enables the network to manage interference at a granular level while significantly reducing the total amount of signaling overhead compared to reporting all frequency points individually.
Solution Approach 2:
The patent applies local quality by allowing different reporting resolutions for different frequency sub-bands. The network can configure the UE to report capability information with varying levels of detail depending on the specific characteristics of each sub-band, optimizing the balance between interference management accuracy and signaling overhead for each local frequency region.
2Measurement precision
If the UE reports detailed intra-UE interference suppression capability information, then the network can perform precise interference avoidance, but the complexity of the reporting mechanism increases
Solution Approach 1:
The reporting mechanism is made dynamic through configurable parameters. The network can adjust the granularity of frequency sub-bands and the level of detail in capability reporting based on actual network conditions and requirements. This dynamic configuration allows the system to adapt between high-precision reporting when needed and simplified reporting when overhead is a concern, reducing overall system complexity.
Solution Approach 2:
The patent utilizes parameter changes by allowing the network to configure various reporting parameters such as sub-band size, reporting periodicity, and capability detail level. These configurable parameters enable the system to optimize the balance between measurement precision and mechanism complexity based on specific operational scenarios, preventing the reporting mechanism from becoming unnecessarily complex.
