Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly 5G NR, face challenges in distinguishing between sensitivity degradation caused by self-interference and other interference, leading to inaccurate network configuration decisions.
Innovation Solution
A UE and network node apparatus are configured to measure and report maximum sensitivity degradation (MSD) with an interference source indication, distinguishing between self-interference and other interference, enabling precise network scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network configures communication resources without distinguishing interference sources, then configuration simplicity is maintained, but measurement precision and decision accuracy deteriorate
Solution Approach 1:
The patent segments the interference measurement by introducing an interference source indication field that separately identifies self-interference versus other interference. This segmentation allows the network to distinguish between different interference sources while maintaining the overall measurement framework, resolving the contradiction between configuration simplicity and measurement precision.
Solution Approach 2:
The interference source indication acts as an intermediary element between the MSD measurement and the network configuration decision. This intermediary provides additional contextual information about the interference source without fundamentally changing the measurement process, enabling more accurate decisions while keeping the configuration relatively simple.
2Productivity
If the network releases configuration due to sensitivity degradation without identifying the cause, then resource allocation speed is maintained, but reliability of communication deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports not only the MSD value but also the interference source indication. This feedback loop enables the network to make informed decisions about whether to release or adjust configuration, improving communication reliability by avoiding premature releases caused by misidentified interference sources while maintaining efficient resource allocation.
Solution Approach 2:
By obtaining the interference source indication before making configuration decisions, the network performs preliminary analysis to determine whether sensitivity degradation is due to self-interference (where configuration adjustment may help) or other interference (where release may be appropriate). This preliminary action prevents hasty configuration releases and improves reliability.
3Reliability
If the network adjusts configuration for all sensitivity degradation cases, then communication reliability is improved, but loss of information about actual interference sources increases
Solution Approach 1:
The patent segments the response to sensitivity degradation by providing differentiated network actions based on the interference source indication. For self-interference cases, the network can adjust configuration parameters; for other interference cases, the network can make informed decisions about resource allocation. This segmentation preserves interference source information while enabling reliable communication through appropriate differentiated actions.

AI summary
Method and apparatus for an enhanced UE MSD indication The apparatus receives a request for a measurement of a MSD. The apparatus measures the MSD caused by self-interference or a different interference than the self-interference. The apparatus reports a report comprising the measurement of the MSD including an interference source indication that the MSD is due to the self-interference, the different interference, or a combination of the self-interference and the different interference.
