Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If digital-analog hybrid beamforming technology is used to reduce equipment cost and baseband processing complexity, then device complexity is reduced, but uplink transmission efficiency deteriorates due to lack of multi-beam transmission schemes
Solution Approach 1:
The patent segments the uplink transmission by configuring multiple pieces of uplink beam information (first, second, and third pieces) associated with different parameters (first, second, and third parameters respectively). This segmentation allows the terminal device to transmit different uplink channels or different parts of uplink data through different beams, thereby improving uplink transmission efficiency while maintaining the simplicity of digital-analog hybrid beamforming architecture.
2Device complexity
If single-beam uplink transmission is used to simplify the transmission scheme, then device complexity is reduced, but uplink transmission efficiency deteriorates
Solution Approach 1:
The patent implements multi-functionality by configuring the terminal device with multiple pieces of uplink beam information that can be universally applied to different uplink transmission scenarios. The first, second, and third pieces of uplink beam information can be associated with different parameters and used for different uplink channels or transmission purposes, making the transmission scheme adaptable and efficient without requiring completely separate systems for each scenario.
