Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming is used to compensate for propagation loss of millimeter waves, then transmission reliability is improved, but transmission capacity and latency are worsened due to single-beam limitation
Solution Approach 1:
The patent segments the single data stream into multiple data pieces and transmits them through multiple independent beams simultaneously. This allows the system to maintain the reliability benefits of beamforming while increasing transmission capacity by utilizing multiple spatial paths in parallel, directly resolving the contradiction between reliability and productivity.
Solution Approach 2:
The patent transitions from single-beam transmission to multi-beam transmission by adding the spatial dimension. Instead of relying on a single beam path, the system creates multiple beam paths in different spatial directions, enabling simultaneous transmission of multiple data pieces and thereby increasing capacity while maintaining reliability through spatial diversity.
2Productivity
If multiple beams are used to increase transmission capacity, then productivity is improved, but system complexity increases
Solution Approach 1:
The patent segments both the data into multiple pieces and the transmission into multiple beams, where each beam handles a specific data piece. This segmentation approach simplifies the control logic compared to complex multi-user MIMO schemes, as each beam can be independently controlled and managed, reducing overall system complexity while maintaining high transmission capacity.
3Productivity
If data is divided into multiple pieces and transmitted through multiple beams, then transmission capacity is improved, but data management complexity increases
Solution Approach 1:
The patent performs preliminary actions by assigning priorities to data pieces before transmission and pre-establishing the correspondence between data pieces and beams. This preliminary organization simplifies the reception and reassembly process, as the receiving end can efficiently match incoming data pieces to their correct positions based on pre-assigned priorities and beam correspondences, reducing data management complexity despite multiple data streams.
