Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data and haptic data are transmitted using the same transmission parameters and resource allocation, then device complexity is reduced, but transmission reliability and delay requirements for haptic data cannot be met
Solution Approach 1:
The patent segments the transmission parameters into two distinct sets: first transmission parameters for video data and second transmission parameters for haptic data. This segmentation allows each data type to be optimized independently according to its specific requirements, with haptic data receiving higher reliability parameters while video data uses parameters optimized for throughput
Solution Approach 2:
The patent applies local quality by assigning different transmission parameter configurations to different data types based on their specific needs. Haptic data transmission uses parameters optimized for reliability and low delay, while video data transmission uses parameters optimized for high rate, allowing each data stream to have locally optimized quality characteristics
2Reliability
If haptic data transmission prioritizes reliability and delay requirements, then haptic data quality is improved, but video data transmission rate is reduced
Solution Approach 1:
The patent divides transmission resources into separate allocations for haptic and video data. By segmenting the resource allocation and parameter sets, the system can guarantee reliability and delay requirements for haptic data without compromising the transmission rate for video data, as each data type operates under its own optimized parameter configuration
Solution Approach 2:
The patent changes transmission parameters dynamically based on data type. Different modulation and coding schemes (MCS), redundancy versions (RV), and new data indicators (NDI) are applied specifically to haptic data transmissions to ensure high reliability, while video data transmissions use parameter configurations that maximize transmission rate
3Productivity
If single set of transmission parameters is used for both video and haptic data, then configuration complexity is reduced, but communication efficiency deteriorates
Solution Approach 1:
The patent segments transmission configurations into distinct sets for different data types. By maintaining separate first transmission parameters for video data and second transmission parameters for haptic data, the system achieves higher communication efficiency through optimized parameter selection, while the segmentation itself manages configuration complexity through structured organization
Solution Approach 2:
The patent creates a universal transmission framework that handles multiple data types with different requirements. The system maintains multiple parameter sets that can be selectively applied based on data type, providing multi-functionality that improves communication efficiency while managing complexity through a unified scheduling mechanism
4Productivity
If video data transmission optimizes for high rate, then video quality is improved, but haptic data transmission reliability and delay requirements are not met
Solution Approach 1:
The patent applies local quality by configuring transmission parameters specifically for each data type's requirements. Video data transmissions use parameter configurations optimized for high rate and throughput, while haptic data transmissions use independently configured parameters optimized for reliability and low delay, allowing each data stream to achieve its local quality optimum without compromising the other
Data Source
AI summary
A data transmission method and a communication apparatus are provided. Transmission of first data (for example, video data) is performed on a part of time-frequency resources on one layer of space division resources (a first space division resource), and transmission of second data (for example, haptic data) is performed on the other part of time-frequency resources on the layer of space division resources, or transmission of the second data is performed on another layer of space division resources (a second space division resource). Two sets of different MCSs, NDIs, and RVs are respectively used for transmission of the first data and transmission of the second data, and the first space division resource and the second space division resource correspond to a same time-frequency resource.
