Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional MIMO communication methods are used with multiple antennas, then data communication rate can be enhanced, but system performance improvement and support for new service forms are limited
Solution Approach 1:
The patent segments the transmission process by separating multicast/broadcast data into multiple independent streams, each processed through separate modulation and mapping stages. This segmentation enables flexible resource allocation and supports diverse service types (e.g., eMBB, uRLLC, mMTC) within the same communication framework, thereby enhancing both productivity and adaptability.
Solution Approach 2:
The patent introduces a new dimension of service differentiation by implementing separate resource allocation and modulation schemes for different data streams. This dimensional expansion allows the system to simultaneously support multiple service forms with different quality requirements, transforming the single-dimension MIMO communication into a multi-dimensional communication system that accommodates diverse service needs.
2Reliability
If single directivity transmission is used, then system complexity is low, but communication performance and reception quality are limited
Solution Approach 1:
The patent merges multiple transmission signals with different directivities into a unified resource allocation framework. By combining the benefits of beamforming (improved reception quality) with a systematic resource management approach, the system achieves enhanced reliability while keeping complexity manageable through shared processing components and standardized procedures.
3Productivity
If multiple transmission signals with different directivities are generated simultaneously, then communication system performance is improved, but transmission unit complexity increases
Solution Approach 1:
The patent applies preliminary action by performing resource allocation, modulation, and mapping operations before the actual transmission. By pre-processing the data streams and determining optimal resource assignments in advance, the transmission unit can efficiently generate multiple signals with different directivities without incurring excessive real-time complexity, thus improving overall system performance while managing computational burden.
