Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resource sharing is implemented between multiple operators in future radio communication systems, then frequency utilization efficiency is improved, but terminal configuration flexibility is reduced and communication quality deteriorates due to interference
Solution Approach 1:
The patent segments the frequency band into multiple resource blocks and assigns different time-frequency resource patterns to different operators. Each operator is configured with specific resource allocations through dedicated configuration information, allowing simultaneous operation on the same frequency band while maintaining individual configuration flexibility and reducing inter-operator interference.
2Productivity
If resource sharing is implemented between multiple operators, then frequency utilization efficiency is improved, but communication quality deteriorates due to interference
Solution Approach 1:
The frequency band is segmented into distinct resource blocks with operator-specific time-frequency patterns, isolating operators from each other's interference while maintaining high overall utilization.
Solution Approach 2:
Different local resource configurations are applied to different operators within the same frequency band. Each operator receives customized configuration information tailored to its specific needs, allowing optimal local performance while sharing the overall frequency resource.
3Reliability
If operator-specific configuration is maintained, then communication quality is improved, but frequency utilization efficiency deteriorates due to redundant resource allocation
Solution Approach 1:
Multiple operators share the same physical frequency band by merging their resource allocations in the time-frequency domain. Through coordinated resource block assignments and pattern-based multiplexing, operators achieve both operator-specific optimization and high overall frequency utilization efficiency.
Solution Approach 2:
The patent introduces time-domain patterns as an additional dimension for resource differentiation. Operators are distinguished not only by frequency allocation but also by time-frequency resource patterns, enabling efficient spectral sharing while maintaining operator-specific configuration benefits.
