Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies lack specific designs for distributed-tone resource unit (dRU) tone plans that support wide distribution bandwidths of 160 MHz and 320 MHz, which are necessary for next-generation wireless local area networks (WLANs) operating in the 6 GHz frequency band.
Innovation Solution
The proposed solution utilizes an 80 MHz dRU tone plan as a basic building block to generate dRUs for wide distribution bandwidths of 160 MHz and 320 MHz, preserving the hierarchical structure and achieving optimal power boost gains through uniform tone distribution and flexible scheduling, allowing for mixed-distribution bandwidth operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If dRU tone plans are designed for wider distribution bandwidths (160 MHz and 320 MHz), then transmission power and coverage are improved, but device complexity and design difficulty increase due to lack of standardized structures
Solution Approach 1:
The patent segments the wide bandwidth (160 MHz or 320 MHz) into multiple 80 MHz sub-blocks, each containing distributed tone RUs. This segmentation allows the system to leverage existing 80 MHz dRU designs while extending to wider bandwidths, reducing overall design complexity.
Solution Approach 2:
The patent implements a nested structure where 80 MHz dRU tone plans are nested within larger 160 MHz and 320 MHz bandwidth structures. The hierarchical organization allows smaller dRU units to be combined systematically to form larger bandwidth allocations.
2Ease of manufacture
If dRUs are constructed using 80 MHz tone plan as building blocks, then manufacturing ease and implementation simplicity improve, but adaptability to different bandwidth configurations may be limited
Solution Approach 1:
The patent creates a universal 80 MHz dRU tone plan that serves multiple functions across different bandwidth configurations. The same basic building block is used for both 160 MHz and 320 MHz implementations, as well as for various dRU sizes (26-tone, 52-tone, 106-tone, etc.), providing multi-functionality.
Solution Approach 2:
The patent enables dynamic configuration where the number and arrangement of 80 MHz sub-blocks can be adjusted based on available bandwidth and user requirements. This allows flexible adaptation to different operational scenarios while maintaining the same fundamental building block structure.
3Power
If uniform tone distribution is maintained across wide bandwidths, then power boost gains are optimized, but device complexity increases due to scheduling and coordination requirements
Solution Approach 1:
The patent segments the wide bandwidth into independent 80 MHz sub-blocks with uniform tone distribution within each block. This segmentation maintains the power boost benefits of uniform distribution while reducing scheduling complexity by allowing independent management of each sub-block.
