Terminal Inter-Modulation Interference Feedback to Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-transceiver terminals experience interference between different radio access technologies (RATs), leading to poor communication performance due to inter-modulation interference, which existing technologies have not effectively addressed.
Innovation Solution
A method where a terminal sends auxiliary information about inter-modulation interference to a network-side device, including identification and interference information, allowing the device to perform processing operations to mitigate the interference, and the terminal or network-side device can autonomously control frequencies to reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal is equipped with multiple transceivers supporting different RATs, then the adaptability and functionality of the terminal are improved, but inter-modulation interference occurs between frequencies causing deterioration of communication performance
Solution Approach 1:
The terminal detects inter-modulation interference between frequencies of different RATs and feeds back auxiliary information including identification information and interference information to the network-side device. The network-side device uses this feedback to determine and execute interference processing operations, creating a closed-loop system that resolves the contradiction between multi-RAT functionality and communication reliability.
Solution Approach 2:
Auxiliary information acts as an intermediary carrier that conveys interference characteristics from the terminal to the network-side device. This intermediary enables the network-side device to understand the interference situation without directly observing the terminal's internal frequency interactions, allowing indirect but effective interference management.
2Reliability
If the terminal sends detailed auxiliary information about inter-modulation interference to the network-side device, then the network-side device can perform precise interference processing, but signaling overhead increases
Solution Approach 1:
The auxiliary information extracts only the essential characteristics of inter-modulation interference (identification information and interference information) from the complex multi-RAT frequency environment. This extracted information is sufficient for the network-side device to perform interference processing without transmitting complete raw data, thereby reducing signaling overhead while maintaining processing effectiveness.
3Reliability
If the network-side device performs processing operations on all frequencies associated with inter-modulation interference, then interference mitigation is improved, but device complexity and operational load increase
Solution Approach 1:
The network-side device performs interference processing operations selectively on specific frequencies identified through the auxiliary information rather than uniformly processing all frequencies. The identification information and interference information enable targeted processing only where inter-modulation interference occurs, reducing operational complexity while maintaining effective interference mitigation.
