Engineering Contradiction Analysis
1Productivity
If wider bandwidths (480 MHz or greater) are used, then system throughput is improved, but device complexity increases due to new MRU combinations and proportional round robin segment parser designs
Solution Approach 1:
The patent divides the wide bandwidth into multiple frequency segments or subblocks, each containing multiple resource units (RUs). This segmentation allows the proportional round robin segment parser to process different spectral resources independently, managing complexity through structured division while enabling wider bandwidth operation for improved throughput.
Solution Approach 2:
The patent applies different modulation and coding schemes (MCS) or quadrature amplitude modulation (QAM) levels to different spectral resources within the wide bandwidth. This local quality approach allows optimization of each frequency segment according to its characteristics, improving overall system throughput while managing complexity through differentiated processing.
2Reliability
If multiple modulation and coding schemes (MCS) or QAM levels are assigned to different spectral resources, then system throughput and link reliability are improved, but device complexity increases
Solution Approach 1:
The patent assigns different modulation and coding schemes (MCS) or QAM levels to different spectral resources based on their specific characteristics and requirements. This local quality approach enables optimization of each frequency segment, improving link reliability through tailored modulation while managing complexity through systematic differentiation.
Solution Approach 2:
The patent implements dynamic adaptation of modulation schemes across different spectral resources, allowing the system to adjust MCS or QAM levels based on channel conditions and throughput requirements. This dynamic approach improves reliability through adaptive modulation while managing complexity through programmable flexibility rather than hardwired configurations.
3Productivity
If unequal modulations (UEQM) are assigned on resource units (RUs) of a given MRU, then system throughput is improved, but ease of operation decreases due to more complex parsing requirements
Solution Approach 1:
The patent segments the MRU into multiple RUs with different modulation schemes, allowing independent processing of each segment. This segmentation enables unequal modulations to be applied to different RUs while maintaining manageable complexity through structured division, improving throughput without proportionally increasing parsing difficulty.
Solution Approach 2:
The patent incorporates feedback mechanisms in the proportional round robin segment parser to track and manage leftover bits across different modulation schemes. This feedback approach enables the parser to handle UEQM systematically by monitoring bit distribution and adjusting processing accordingly, improving throughput while maintaining operational feasibility through intelligent bit management.

AI summary
Various schemes pertaining to proportional round robin segment parser designs for the wider bandwidths and corresponding multi-resource unit (MRU) combinations with either equal modulation (EQM) or unequal modulation (UEQM) in wireless communications are described. An apparatus (e.g., an access point (AP) or a non-AP station (STA)) generates a multi-resource unit (MRU) comprising an aggregate of a plurality of resource units (RUS). The apparatus then transmits the MRU with UEQM or EQM in a bandwidth of 480 MHz or greater.
