UE Frequency-Domain Interference Measurement for Cross-Link Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies due to interference issues, particularly cross-link interference (CLI), which arise from unsynchronized uplink and downlink transmissions, leading to resource waste and suboptimal user equipment (UE) performance.
Innovation Solution
The terminal device determines a specific first frequency domain resource within a pre-configured resource block (RB) range for interference measurement or received energy measurement, optimizing the use of frequency domain resources by avoiding unnecessary waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If interference measurement or received energy measurement is performed over the whole bandwidth, then measurement accuracy is improved, but frequency domain resource waste increases
Solution Approach 1:
The patent divides the entire bandwidth into multiple frequency domain resources (first frequency domain resource and second frequency domain resource). The terminal device performs interference measurement or received energy measurement only on the first frequency domain resource, which is a segment of the total bandwidth. This segmentation approach maintains measurement accuracy on the critical resource while avoiding unnecessary measurements on other resources, thus reducing frequency domain resource waste.
2Reliability
If the terminal device performs measurements over the whole bandwidth, then measurement reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the bandwidth into multiple frequency domain resources and configures different measurement parameters for each segment. The terminal device applies different measurement configurations to different segments based on their specific characteristics, which simplifies the overall measurement process while maintaining reliability through targeted measurements on each segment.
Solution Approach 2:
The patent implements partial measurement action by performing interference measurement or received energy measurement only on the first frequency domain resource rather than the entire bandwidth. This partial action approach maintains sufficient measurement reliability for the critical resource while reducing device complexity by avoiding unnecessary measurements on other resources.
