Self-Interference Measurement Reporting for Full-Duplex UE Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in 5G NR, face challenges with self-interference and cross-link interference in full-duplex operations, which affect communication quality and efficiency.
Innovation Solution
A method and apparatus for user equipment (UE) to receive scheduling information including timing for reporting self-interference measurements, allowing the UE to transmit a self-interference measurement report to the network node, thereby enabling the network to reduce communication overhead and improve network throughput by managing self-interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-interference measurements are reported frequently to improve interference management, then communication quality improves, but communication overhead increases
Solution Approach 1:
The system implements partial reporting by selectively reporting self-interference measurements only when they exceed a threshold or when scheduled by the network, rather than reporting all measurements continuously. This reduces overhead while maintaining adequate interference management through targeted reporting of significant interference events.
2Productivity
If self-interference measurement reporting is implemented in full-duplex operations, then spectral efficiency improves, but system complexity increases
Solution Approach 1:
The UE autonomously performs self-interference measurements and generates reports without requiring complex centralized control for each measurement instance. The network node provides scheduling information and thresholds, but the UE independently executes measurements and determines reporting timing, reducing overall system complexity while enabling spectral efficiency improvements through interference management.

AI summary
The UE in a FD operation may receive scheduling information including timing information for reporting a self-interference measurement, and transmit a self-interference measurement report including the self-interference measurement based on the scheduling information received from a network node. The UE may transmit a request for the self-interference measurement report to the network node prior to receiving the scheduling information.
