XDD Resource Configuration for Conflict-Free UL and DL Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XDD technologies face challenges in resource configuration between network and terminal devices, leading to conflicts and inefficiencies in UL and DL transmissions due to unclear transmission directions on frequency domain resources.
Innovation Solution
The solution involves configuring UL and non-UL frequency domain resources with the same time domain on a time domain resource unit, enabling the terminal device to determine precise resource locations through received configuration information, thereby avoiding conflicts and improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource configuration information is not clearly defined for UL and non-UL frequency domain resources, then transmission conflicts occur between network and terminal devices, but providing detailed configuration information increases system complexity
Solution Approach 1:
The patent applies preliminary action by pre-configuring resource location information for UL and non-UL frequency domain resources before transmission occurs. The network device sends resource configuration information to the terminal device in advance, indicating the resource locations on time domain resource units, so that both devices can avoid transmission conflicts without requiring complex real-time coordination mechanisms.
2Productivity
If UL and non-UL frequency domain resources are configured without clear time domain separation, then resource utilization efficiency improves, but transmission conflicts between UL and DL occur
Solution Approach 1:
The patent applies segmentation by dividing frequency domain resources into distinct UL frequency domain resources and non-UL frequency domain resources, each with specifically indicated resource locations on time domain resource units. This segmentation allows simultaneous configuration of UL and DL resources in the same time domain without conflicts, as each resource type has its designated location information.
Solution Approach 2:
The patent applies local quality by providing specific resource location information for different frequency domain resources at different time domain positions. The resource configuration information indicates precise resource locations on time domain resource units, allowing UL and non-UL resources to coexist in the same time domain with locally differentiated allocation, improving overall resource utilization while avoiding conflicts.
3Measurement precision
If resource configuration information is sent frequently to ensure accurate resource allocation, then transmission accuracy improves, but signaling overhead increases
Solution Approach 1:
The patent applies universality by designing a multi-functional resource configuration information structure that simultaneously provides resource location indication, time domain resource unit identification, and transmission direction specification. This unified configuration approach achieves accurate resource allocation without requiring multiple separate signaling messages, thereby reducing overall signaling overhead while maintaining high allocation accuracy.
