Current technologies lack an optimized method for distributing subcarriers to construct distributed-tone resource units (dRUs) and distributed-tone multi-resource units (dMRUs) for efficient transmission in 6 GHz low-power indoor (LPI) systems, which are subject to stringent regulatory limits.
Innovation Solution
The proposed solution involves distributing a plurality of subcarriers to generate dRUs or dMRUs on an 80 MHz frequency segment, utilizing a processor to manage the distribution and communication with communication entities, thereby optimizing the design for enhanced power boost and coverage.

Engineering Contradiction Analysis
1Power
If distributed-tone RUs (dRUs) and distributed-tone multi-RUs (dMRUs) are used to spread subcarriers over wider bandwidth, then transmit power is boosted and coverage range is extended, but the distribution method of subcarriers in constructing dRUs of different sizes remains undefined and suboptimal
Solution Approach 1:
The patent segments the 80 MHz frequency band into multiple subblocks and further divides subcarriers within each subblock to construct dRUs and dMRUs of different sizes. This segmentation approach enables systematic distribution of subcarriers across frequency resources, resolving the undefined distribution method while maintaining power boost benefits.
Solution Approach 2:
The patent applies different subcarrier distribution patterns to different frequency subblocks and dRU/dMRU sizes. By optimizing the distribution locally for each configuration rather than using a uniform approach, the patent achieves optimal power boost gains for various dRU/dMRU sizes while maintaining manageable design complexity.
2Power
If dRUs and dMRUs are constructed with optimized subcarrier distribution, then power boost gains and coverage extension are achieved, but stringent EIRP limits in 6 GHz LPI systems constrain the available transmit power
Solution Approach 1:
The patent transitions from concentrating power in a single frequency location to distributing power across multiple frequency dimensions (subblocks and subcarriers). This dimensional expansion allows the system to achieve effective power boost and coverage extension while maintaining compliance with EIRP limits by spreading the transmitted energy across a wider frequency spectrum.
Solution Approach 2:
The patent changes the distribution parameters of subcarriers across frequency resources, optimizing the density and spacing of subcarriers in different dRU/dMRU configurations. By adjusting these distribution parameters, the system achieves optimal power efficiency and coverage within the constrained EIRP limits of 6 GHz LPI systems.
3Length of stationary object
If subcarriers are spread over wider bandwidth to extend coverage, then transmission reach is improved, but the optimization method for different dRU sizes remains undefined
Solution Approach 1:
The patent segments the frequency bandwidth into subblocks and systematically distributes subcarriers across these segments to construct dRUs of different sizes. This segmentation provides a clear, defined method for subcarrier distribution that extends coverage while maintaining manageable design complexity through structured organization.
Solution Approach 2:
The patent develops a universal subcarrier distribution framework that can construct dRUs of various sizes (26-tone, 52-tone, 106-tone, 242-tone, 484-tone) using the same fundamental principles. This multi-functional approach covers all dRU size configurations without requiring separate undefined methods for each size, thereby extending coverage with a unified, manageable design.

AI summary
Various schemes pertaining to optimization of distributed-tone resource unit (dRU) and distributed-tone multi-resource unit (dMRU) designs for transmission in a 6 GHz low-power indoor (LPI) system are described. An apparatus distributes a plurality of subcarriers of a resource unit (RU) to generate a dRU or a distributed-tone multi-RU (dMRU) on an 80 MHz frequency segment or subblock. The apparatus then communicates with a communication entity using the dRU or the dMRU.
