Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems, particularly those using millimeter waves around 52.6 GHz and above, face challenges with beamforming and timing issues, leading to complications in data signaling and resource management.
Innovation Solution
A method for operating receiving radio nodes that configures code block distribution across overlapping signaling resource structures, allowing for the omission or dropping of data signaling associated with specific resource structures, thereby prioritizing indication signaling without additional control signaling, facilitating efficient scheduling and processing of long data transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data signaling is transmitted according to code block distribution mapped to signaling resource structures, then data transmission efficiency is improved, but resource conflicts occur when indication signaling overlaps with data signaling resources
Solution Approach 1:
The patent extracts the conflicting data signaling from the overlapping time-frequency resources when indication signaling is detected. The receiving node identifies the overlap between data signaling resource structure and indication signaling resources, then removes (drops) the data signaling transmission in those specific overlapping allocation units, preventing resource conflicts while maintaining data transmission in non-overlapping resources.
Solution Approach 2:
The patent implements dynamic resource management where the data signaling transmission is adaptively adjusted based on the presence of indication signaling. The system dynamically determines whether to transmit or drop data signaling in each allocation unit based on real-time detection of indication signaling, making the resource allocation flexible rather than static.
2Reliability
If indication signaling is prioritized over data signaling in overlapping resources, then signaling reliability is improved, but data transmission completeness deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the treatment of data signaling in different spatial-temporal locations. In allocation units where indication signaling is present, data signaling is dropped to ensure signaling reliability. In allocation units where no indication signaling overlaps, data signaling is transmitted normally to maintain data completeness. This localized selective dropping resolves the contradiction by preserving data in non-conflicting regions.
3Adaptability or versatility
If code block distribution is mapped to overlapping signaling resource structures, then resource utilization is improved, but decoding complexity increases
Solution Approach 1:
The patent segments the data transmission into multiple code block groups, each associated with specific allocation units in the signaling resource structure. When indication signaling overlaps with certain allocation units, only the corresponding code block groups are dropped, while other code block groups continue transmission. This segmentation allows selective handling of different data portions, managing decoding complexity through structured organization.
