Data Parsing for Non-Contiguous Resource Unit Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially those supporting high efficiency (HE) and extremely high throughput (EHT) operations, there is a challenge in discovering contiguous idle channels within extended basic service set (BSS) bandwidths due to overlapping data traffic and resource occupancy by incumbent technologies like 4G and 5G systems, leading to reduced signaling throughput and wasted frequency resources.
Innovation Solution
The system divides the available frequency spectrum into multiple resource units (RUs), allowing for flexible channel configuration and aggregation of noncontiguous bandwidth segments, with data parsing and encoding schemes that distribute bits across these RUs for efficient communication, using methods like joint encoding, separate encoding, and interleaving to ensure reliable transmission.

Engineering Contradiction Analysis
1Productivity
If the available frequency spectrum is divided into multiple resource units (RUs) and noncontiguous bandwidth segments are aggregated, then spectral efficiency and signaling capability are improved, but device complexity and data distribution complexity increase
Solution Approach 1:
The available frequency spectrum is divided into multiple resource units (RUs), each comprising a number of different frequency subcarriers (tones). This segmentation enables flexible allocation and aggregation of noncontiguous bandwidth segments, improving spectral efficiency while managing complexity through structured division of the frequency domain.
Solution Approach 2:
The patent introduces a new dimension for data distribution by mapping data bits across multiple RUs in the frequency domain rather than sequentially in time or space. This dimensional approach to data allocation optimizes spectral utilization and signaling capability while providing a systematic method to handle the complexity of noncontiguous bandwidth aggregation.
2Adaptability or versatility
If incumbent technologies occupy resources of the extended BSS bandwidth, then communication diversity is improved, but available frequency resources are wasted and signaling throughput is reduced
Solution Approach 1:
By segmenting the extended BSS bandwidth into multiple RUs, the system can identify and aggregate only the idle or available frequency segments. This allows the system to adapt to the presence of incumbent technologies by selecting noncontiguous available resources, thereby maintaining communication diversity while optimizing signaling throughput through efficient resource utilization.
Solution Approach 2:
The patent implements dynamic resource allocation where the system can flexibly aggregate different combinations of noncontiguous RUs based on real-time availability. This dynamic approach enables the system to adapt to changing spectral conditions caused by incumbent technologies, maximizing the use of available frequency resources while maintaining diverse communication capabilities.

AI summary
This disclosure provides methods, devices and systems for data parsing for resource unit (RU) aggregation. A wireless communication device (such as an access point (AP) or a station (STA)) may allocate a set of RUs for a receiving device in a basic service set (BSS). The set of RUs may be associated with multiple bandwidth segments of a bandwidth allocation and may be non-contiguous or contiguous. The wireless communication device may determine a data parsing and encoding scheme for a set of information bits. The data parsing may be implemented at a medium access control (MAC) layer or physical (PHY) layer and the encoding may correspond to a joint encoding or a separate encoding for each RU of the allocation. The wireless communication device may then distribute the coded bits to the set of RUs for transmission.
