Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems limit service data transmission flexibility by using fixed subcarrier spacings at fixed frequencies, failing to accommodate the diverse requirements of different service types such as eMBB, URLLC, and mMTC.
Innovation Solution
A data transmission method and system that supports data transmission using multiple subcarrier spacings at the same or different frequencies, allowing for flexible configuration of parameters like subcarrier spacing, cyclic prefix, time units, and resource blocks to enhance service diversity and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed subcarrier spacing is used at fixed frequency, then system complexity is reduced, but service adaptability deteriorates
Solution Approach 1:
The patent implements dynamic parameter configuration where subcarrier spacing and frequency parameters can be flexibly adjusted based on service requirements. The system transitions from fixed parameters to dynamically configurable parameters, allowing different service types (eMBB, URLLC, mMTC) to utilize appropriate parameter settings without increasing overall system complexity through rigid structures.
Solution Approach 2:
The patent changes physical parameters (subcarrier spacing, frequency) to accommodate different service characteristics. By allowing parameter variations across different service types and scenarios, the system achieves high adaptability while maintaining manageable complexity through standardized parameter sets.
2Adaptability or versatility
If multiple subcarrier spacings are supported at same or different frequencies, then service adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the communication system into multiple parameter configurations, each optimized for specific service types. By dividing the parameter space into discrete, manageable sets (different subcarrier spacings, frequency ranges), the system can support diverse services without requiring continuous parameter adjustment, thus controlling device complexity.
Solution Approach 2:
The patent creates a universal framework that can handle multiple service types through a common multi-parameter system. The same system infrastructure supports different subcarrier spacings and frequency configurations, allowing one system to perform multiple service functions without requiring separate dedicated systems for each service type.
