Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional beam management methods are used in THz communication systems, then the system can operate with legacy antenna structures, but beam gain and steering capabilities are insufficient for THz frequency requirements
Solution Approach 1:
The antenna structure is divided into multiple antenna elements arranged in arrays, with each element contributing to the overall beamforming capability. This segmentation allows independent control of each element's phase and amplitude, enabling precise beam steering and enhanced gain without requiring a complete redesign of the entire antenna system.
Solution Approach 2:
The patent implements a hierarchical beam management structure where beam management regions are nested within communication frames, and transition time regions are nested within beam management regions. This nested organization allows multiple levels of beam control (wide-beam and narrow-beam switching) to coexist efficiently, achieving high beam gain while managing system complexity through structured time-resource allocation.
2Adaptability or versatility
If beam management region is added to communication frame, then beam steering capability is enhanced, but transmission time is reduced for actual data communication
Solution Approach 1:
Beam management regions are configured periodically within communication frames at optimized intervals. This periodic structure allows the system to perform beam steering and beam management operations at regular intervals while maintaining data transmission during the remaining time, thus enhancing beam steering capability without continuously sacrificing transmission time.
Solution Approach 2:
Beam management operations including beam steering are performed in advance during designated beam management regions before actual data transmission begins. This preliminary action ensures that optimal beams are established beforehand, allowing subsequent data transmission to proceed efficiently without time loss during beam switching.
3Reliability
If transition time region is allocated for beam switching, then beam switching reliability is improved, but communication efficiency deteriorates due to additional time overhead
Solution Approach 1:
The patent allocates transition time regions only when and where beam switching is actually required, rather than continuously reserving time for beam management. This partial action approach provides sufficient transition time for reliable beam switching while minimizing the overall time overhead, thus maintaining communication efficiency.
Solution Approach 2:
The beam management region configuration is made dynamic and adaptable based on actual communication conditions. The system can adjust the frequency and duration of beam management regions according to channel conditions, mobility requirements, and traffic patterns, ensuring reliable beam switching only when necessary while maximizing communication efficiency during stable conditions.
