Engineering Contradiction Analysis
1Productivity
If spectrum resources are allocated to multiple resource utilization systems, then spectrum utilization efficiency is improved, but network interference increases
Solution Approach 1:
The interference overlapping map is segmented into multiple layers representing different priority levels of resource utilization systems. High-priority systems are allocated first, followed by low-priority systems, with interference constraints enforced between layers. This segmentation allows multiple systems to share spectrum resources while controlling interference through hierarchical resource allocation.
Solution Approach 2:
The patent introduces an intermediary mechanism (the interference overlapping map and resource allocation manager) that mediates between multiple resource utilization systems. This intermediary constructs the interference map, identifies conflicting allocations, and adjusts resource assignment to eliminate harmful interference while maintaining high spectrum utilization through coordinated multi-system operation.
2Measurement precision
If interference overlapping map is constructed with all interference relationships, then interference management accuracy is improved, but system complexity increases
Solution Approach 1:
The interference overlapping map is segmented into hierarchical layers based on priority levels. Each layer represents a specific priority group, and interference relationships are managed within and between layers. This segmentation reduces complexity by organizing the full interference map into manageable segments that can be processed systematically through layered resource allocation algorithms.
Solution Approach 2:
The interference overlapping map is constructed dynamically based on current system conditions and priority requirements. The map adapts to changing interference relationships and resource availability, allowing the system to maintain accurate interference management without being constrained by fixed, complex static structures. Dynamic construction enables the system to focus computational resources on relevant interference relationships.

AI summary
Provided are an electronic device and method for wireless communication, and a computer-readable storage medium. The electronic device comprises: a processing circuit, configured to: construct an interference overlapping diagram based on an interference/coexistence relationship between resource application systems within a management range, wherein a connection point of the interference overlapping diagram represents one or more resource application systems, and an edge of the interference overlapping diagram represents the fact that interference exists between the resource application systems represented by two connection points linked with the edge; remove one or more edges in the interference overlapping diagram so as to enable the interference overlapping diagram to meet a pre-determined condition after the removal; and carry out channel/resource allocation based on the adjusted interference overlapping diagram.
