Dynamic Duplex Mode Switching for Self-Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in flexibly adjusting duplex modes to adapt to actual situations, as terminals often support only half-duplex mode due to self-interference limitations, while full-duplex mode can cause interference and quality issues.
Innovation Solution
A method where a terminal sends indication information to a network side device about its duplex mode capabilities, and the network side device determines the appropriate duplex mode based on this information, channel state, power parameters, and interference-related information.

Engineering Contradiction Analysis
1Productivity
If full-duplex mode is used, then throughput and transmission efficiency are improved, but self-interference and communication quality deteriorate
Solution Approach 1:
The patent implements dynamic switching between full-duplex and half-duplex modes based on real-time channel conditions, terminal capabilities, and network status. The network side device determines the appropriate duplex mode and configures it dynamically, allowing the system to adapt to changing conditions and optimize throughput while avoiding excessive self-interference.
Solution Approach 2:
The patent changes the duplex mode parameter based on channel state information, terminal power parameters, and interference-related information. By adjusting this key operational parameter dynamically, the system achieves optimal balance between throughput and self-interference management.
2Loss of time
If full-duplex mode is used, then transmission delay is reduced, but interference-related quality issues worsen
Solution Approach 1:
The system dynamically adjusts duplex mode based on real-time assessment of communication quality metrics including channel state and interference levels. This allows the system to maintain low transmission delay when conditions permit full-duplex operation while switching to half-duplex mode when communication quality would deteriorate.
Solution Approach 2:
The patent employs feedback mechanisms where the terminal reports channel state information and the network side device monitors interference-related information. This feedback loop enables the system to adapt duplex mode configuration to maintain both low transmission delay and high communication quality.
3Object-generated harmful factors
If half-duplex mode is used, then self-interference is reduced, but throughput and transmission efficiency worsen
Solution Approach 1:
Instead of statically operating in half-duplex mode, the system dynamically switches between half-duplex and full-duplex modes based on terminal capabilities and network conditions. This allows the system to achieve high throughput when full-duplex is beneficial while falling back to half-duplex when self-interference becomes problematic.
Solution Approach 2:
The patent changes the duplex mode parameter based on terminal self-interference suppression capability and network conditions. Terminals with better self-interference suppression can operate in full-duplex mode for higher throughput, while those with limited capability operate in half-duplex mode to avoid self-interference issues.
4Device complexity
If duplex mode is fixed, then device complexity is reduced, but adaptability to different scenarios worsens
Solution Approach 1:
The terminal autonomously reports its duplex mode capability and channel state information to the network side device. The network side device then autonomously determines the appropriate duplex mode configuration based on received information and network conditions, reducing the need for complex manual configuration while maintaining high adaptability.
Solution Approach 2:
The system uses feedback from terminal capability reports and channel state information to automatically adapt duplex mode configuration to different scenarios. This feedback-driven approach maintains low device complexity while achieving high scenario adaptability through automated decision-making.
