Solution Overview
Problem
Existing wireless communication systems face challenges in managing self-interference in full duplex mode, particularly when using multiple antenna panels, which can lead to signal degradation and reduced communication efficiency.
Innovation Solution

Engineering Contradiction Analysis
1Productivity
If full duplex mode is used with multiple antenna panels, then communication efficiency is improved, but self-interference increases causing signal degradation
Solution Approach 1:
The system segments the antenna panels into different functional groups - some panels are designated for transmission while others are designated for reception. This spatial segmentation allows full duplex operation by physically separating the transmit and receive paths, thereby reducing self-interference while maintaining communication efficiency.
Solution Approach 2:
The patent introduces self-interference metrics as an intermediary parameter that mediates between transmission and reception operations. These metrics are measured and reported to the network, which then uses them to configure appropriate full duplex parameters, effectively managing the self-interference issue while enabling efficient full duplex communication.
2Reliability
If self-interference metrics are measured and reported, then full duplex configuration is optimized, but device complexity increases
Solution Approach 1:
The user equipment performs self-measurement of self-interference metrics using its own antenna panels and reports these metrics to the network. This self-service approach allows the device to autonomously characterize its own interference environment without requiring external measurement infrastructure, optimizing full duplex configuration while managing complexity through standardized reporting procedures.
