Preconfigured PUSCH Resource Signaling for Uplink Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network side devices lack knowledge about the need and specific requirements for preconfigured uplink resources by terminals, leading to suboptimal resource allocation.
Innovation Solution
Terminals send auxiliary information to network side devices regarding their configuration needs for preconfigured physical uplink shared channel (PUSCH) resources, including preferred configurations, service status, and resource release requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network side device preconfigures uplink resources without knowing terminal needs, then resource allocation is simplified, but resource utilization efficiency deteriorates
Solution Approach 1:
The terminal sends auxiliary information to the network side device to indicate its need for preconfigured uplink resources and preferred configuration parameters. This feedback mechanism enables the network side device to adjust resource allocation based on actual terminal requirements, resolving the contradiction between simplified allocation and efficient utilization.
Solution Approach 2:
The network side device preconfigures uplink resources in advance based on auxiliary information received from terminals. This preliminary action allows the system to prepare resources before actual transmission needs arise, improving allocation efficiency while maintaining simplicity through pre-established configuration templates.
2Device complexity
If the network side device configures uplink resources without terminal demand information, then configuration process is simplified, but adaptability to terminal needs deteriorates
Solution Approach 1:
The terminal provides auxiliary information including indication information about resource needs and preferred configuration parameters. This feedback enables the network side device to adapt configurations to specific terminal requirements while maintaining a simplified configuration process through standardized information exchange protocols.
Solution Approach 2:
The system exchanges configuration parameters between terminal and network side device based on auxiliary information. By adjusting parameters such as resource quantity, timing, and formatting according to terminal needs, the system achieves adaptability without complicating the overall configuration process.
3Measurement precision
If the terminal sends auxiliary information about configuration needs, then resource allocation accuracy is improved, but communication overhead increases
Solution Approach 1:
The terminal extracts and sends only the necessary auxiliary information required for resource allocation decisions, such as indication information and preferred configuration parameters. This selective information transmission achieves accurate resource allocation while minimizing communication overhead by excluding unnecessary data.
Solution Approach 2:
The system transmits partial auxiliary information that is sufficient for network side device to make accurate allocation decisions. By providing only the essential information needed for configuration rather than all possible terminal data, the system achieves adequate accuracy without excessive communication overhead.
