Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where terminal stations support different standards and communication schemes, the use of older radio frames reduces transmission efficiency due to the inability to utilize high-efficiency radio frames defined by newer standards like IEEE 802.11ax, especially in simultaneous transmission scenarios.
Innovation Solution
A radio communication method and system where a centralized control station calculates and updates setting and switching policies for base stations to select the appropriate radio communication units based on the communication schemes of terminal stations, ensuring adaptability to the IEEE 802.11ax standard, thereby maximizing radio frame efficiency and improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radio frame based on old standards is used to secure backward compatibility, then compatibility with terminal stations supporting older standards is maintained, but transmission efficiency is reduced because high-efficiency radio frames defined by new standards cannot be used
Solution Approach 1:
The base station is divided into multiple radio communication units (first radio communication unit and second radio communication unit), where each unit is dedicated to handling terminal stations of different standard types. This segmentation allows the system to simultaneously support both old and new standards without forcing all terminals to use inefficient old-standard frames, thereby resolving the contradiction between backward compatibility and transmission efficiency.
Solution Approach 2:
Different radio communication units are assigned different communication schemes based on local requirements - the first unit handles terminals supporting new standards with high-efficiency radio frames, while the second unit handles terminals supporting only old standards. This local quality differentiation enables each unit to operate optimally for its specific terminal type, achieving both compatibility and efficiency in appropriate contexts.
2Productivity
If simultaneous transmission is enabled in radio stations based on IEEE 802.11ax standard, then transmission efficiency is improved, but simultaneous transmission cannot be started when radio frames based on conventional standards are used
Solution Approach 1:
By segmenting the base station into specialized radio communication units, the system can dedicate the first unit to IEEE 802.11ax standard terminals that support simultaneous transmission, while the second unit handles conventional standard terminals. This allows simultaneous transmission to be activated in the first unit without preventing conventional terminals from being served by the second unit, thus achieving both improved transmission efficiency and multi-standard support.
3Adaptability or versatility
If a base station is mounted with radio communication units capable of supporting multiple standards, then adaptability to different terminal stations is improved, but device complexity increases
Solution Approach 1:
Instead of making each radio communication unit support all standards (which would increase complexity), the system segments functionality across multiple units - the first unit is optimized for new standards while the second unit handles old standards. This segmentation distributes complexity across separate units rather than concentrating it in each individual unit, making the overall system more manageable while maintaining multi-standard support capability.
