Wireless Data Transmission with Non-Overlapping Reference Signal Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication scenarios involving intelligent terminals, particularly in vehicles, the flexibility and reliability of data transmission are compromised due to resource conflicts among different types of data and reference signals, leading to degraded transmission performance and reduced communication efficiency.
Innovation Solution
A data transmission method that allocates non-overlapping time-frequency resources for different types of data and reference signals, ensuring that demodulation performance and communication efficiency are improved by configuring distinct time-domain and frequency-domain resources for each type of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If shared time-frequency resources are used for multiple service types, then resource utilization efficiency is improved, but transmission reliability and demodulation performance deteriorate due to resource conflicts
Solution Approach 1:
The patent segments time-frequency resources by creating separate resource pools for different service types (e.g., URLLC and eMBB). Each service type is allocated dedicated resources within its pool, preventing resource conflicts between services while maintaining high utilization within each pool through independent scheduling.
Solution Approach 2:
The patent introduces a new dimension of resource management by implementing hierarchical resource pooling - separating resources not only by service type but also by priority levels and traffic types. This multi-dimensional segmentation allows fine-grained resource allocation that simultaneously improves utilization efficiency and transmission reliability.
2Adaptability or versatility
If flexible resource allocation is implemented for multiple service types, then adaptability is improved, but resource conflicts increase leading to degraded transmission performance
Solution Approach 1:
The patent implements dynamic resource allocation within segmented resource pools. Schedulers can dynamically assign resources based on real-time service requirements, traffic conditions, and priority levels while maintaining the structural separation that prevents conflicts. This dynamic flexibility enables high adaptability without sacrificing transmission performance.
Solution Approach 2:
The patent applies different resource allocation strategies and scheduling policies to different service types and priority levels within their respective pools. Each pool can be optimized with locally appropriate quality parameters, allowing high adaptability for specific services while maintaining overall system performance through localized optimization rather than uniform allocation.

AI summary
A data transmission method and apparatus that may be applied to short-range wireless communication, for example, a cockpit domain includes receiving at least one piece of first configuration information from a first node, where the at least one piece of first configuration information indicates at least one of a first time-domain resource or a first frequency domain resource, where the first time-domain resource or the first frequency domain resource is used to carry first data and a first reference signal, and where the first reference signal is a demodulation reference signal of the first data; and transmitting the first reference signal on a second time-frequency resource, where the second time-frequency resource does not overlap a third time-frequency resource.
