Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) systems, receiver sensitivity is degraded due to harmonic and intermodulation interference in frequency band combinations, leading to ineffective utilization of these combinations as the network device cannot accurately determine the actual interference levels of individual terminal devices.
Innovation Solution
A method where the terminal device sends first indication information to the network device, indicating interference information of a frequency band combination, allowing the network device to perform configuration operations that align with the actual interference levels of the terminal device, thereby optimizing the use of each frequency band combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network device configures frequency band combinations without considering terminal-specific interference characteristics, then the network device can simplify the configuration process, but the receiver sensitivity degradation due to harmonic or intermodulation interference cannot be effectively addressed
Solution Approach 1:
The terminal device measures the actual interference level in the frequency band combination and feeds back this information to the network device. The network device then adjusts the frequency band configuration based on this feedback, creating a closed-loop system that adapts to terminal-specific interference characteristics while maintaining manageable configuration complexity
Solution Approach 2:
The network device changes configuration parameters (frequency band combinations) based on the interference level information received from the terminal device. This allows dynamic adaptation of the system to different terminal interference characteristics without requiring complex predetermined configurations
2Productivity
If the network device performs detailed configuration operations for each terminal device based on interference information, then the frequency band utilization can be optimized, but the network device operation complexity increases
Solution Approach 1:
The terminal device autonomously measures its own interference level and generates the configuration request message, eliminating the need for the network device to perform complex measurements and analyses. This self-service approach optimizes frequency band utilization while keeping network device operations simple
Solution Approach 2:
The terminal device performs the interference measurement and configuration determination in advance, preparing the configuration request message before submitting it to the network device. This preliminary action reduces the operational burden on the network device while ensuring optimized frequency band configuration
