Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IDMA is applied to reduce inter-cell interference and intracell interference, then communication reliability is improved, but device complexity increases due to advanced interleave setting and deinterleave setting requirements
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting interleave lengths and patterns based on communication conditions. The base station and terminal device adaptively modify interleave parameters to optimize interference cancellation performance while managing computational complexity, resolving the contradiction between reliability improvement and device complexity increase.
2Productivity
If adaptive interleave length and pattern control is implemented, then communication capacity increases, but processing time increases due to advanced signal processing requirements
Solution Approach 1:
The patent implements preliminary action by pre-configuring interleave patterns and lengths based on channel conditions and traffic requirements. The base station prepares multiple interleave configurations in advance, allowing the system to quickly adapt to changing conditions without extensive real-time processing, thus increasing communication capacity while minimizing processing time delays.
