Dynamic Resource Allocation for Radio Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in managing frequency interference due to limited spectral resources, where existing anti-jamming solutions are either insufficient or cannot be implemented simultaneously, impacting communication quality and resource efficiency.
Innovation Solution
A method for dynamic resource allocation in communication networks, where user equipment is classified based on interference levels, allowing for frequency band changes and beam configuration adjustments to optimize spectral resource use, with high-interference users switching to new frequency bands and low-interference users maintaining existing frequencies and improving beam formation.

Engineering Contradiction Analysis
1Object-affected harmful factors
If frequency foldback solution is implemented, then interference protection is provided, but spectral resources are limited and performance is impacted
Solution Approach 1:
The user equipment population is segmented into multiple classes based on interference impact levels. High-interference users receive frequency foldback protection while low-interference users maintain original frequencies, allowing differentiated resource allocation that conserves spectral resources while protecting those who need it most
Solution Approach 2:
Frequency foldback is applied locally to specific user equipment experiencing high interference rather than uniformly to all users. This localized application ensures spectral resources are not wasted on users who don't need protection while providing targeted assistance to those suffering from interference
2Object-affected harmful factors
If directional beamforming is used, then some interference protection is achieved, but it is insufficient against persistent jamming
Solution Approach 1:
The invention merges directional beamforming with frequency foldback into a hybrid approach. Beamforming provides spatial selectivity to focus energy toward legitimate users while frequency foldback provides spectral avoidance for heavily interfered users, creating a more robust multi-layered defense against jamming
3Object-affected harmful factors
If frequency change is applied to all users, then interference is avoided, but spectral resources are wasted
Solution Approach 1:
Frequency foldback is applied partially only to the subset of users experiencing high interference rather than excessively to all users. This partial action principle ensures spectral resources are conserved for users who can communicate effectively on original frequencies while providing frequency changes only where necessary

AI summary
Method for dynamically allocating resources for radio wave communication between a base station (10) of a communication network and user equipment (25). The method includes, in response to a detection (E0) of interference between the base station (10) and one or more user devices (25), a step of assigning the user devices (25) to at least two classes of user devices based on at least one level of impact of the detected interference on the communication between the respective user device and the base station.Then, depending on the allocation, for user equipment of at least one high interference class, a change (E3a) of at least one frequency band or sub-band for their communication with the base station; for user equipment of at least one low interference class, the frequency bands and sub-bands for their communication with the base station remain unchanged (E3b). There is also a configuration (E3c) of beams from the base station (10) to user equipment (25) of at least one interference class other than the high interference class.
