Sidelink Resource Allocation Mode Selection in NR Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the New Radio (NR) system, terminals are configured with multiple resource allocation modes for the sidelink interface, but they cannot support simultaneous transmission of two transmission blocks on the same frequency band, necessitating a method to determine the allowed resource allocation mode at a specific time on a specific frequency band.
Innovation Solution
A resource allocation mode determining method that involves obtaining configuration information for the sidelink interface, prioritizing between scheduled and selected resource allocation modes based on protocol agreements, network configuration, or terminal-determined priorities, to select the appropriate mode for use on a preset frequency band at a preset time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal is configured with multiple resource allocation modes for the sidelink interface, then the adaptability and service diversity are improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting resource allocation mode parameters based on frequency band and time conditions. The network device configures different resource allocation modes for different frequency bands and time periods, allowing the terminal to adapt to varying service requirements without manual intervention. This resolves the contradiction by automating the parameter selection process, maintaining high adaptability while reducing operational complexity.
Solution Approach 2:
The patent implements dynamics by enabling the terminal to dynamically switch between different resource allocation modes based on current operating conditions. The resource allocation mode is not fixed but changes according to the frequency band being used and the time of operation. This dynamic approach allows the system to maintain optimal performance across diverse scenarios while the automation of mode selection prevents the complexity from becoming unmanageable.
2Adaptability or versatility
If the terminal supports multiple resource allocation modes simultaneously, then the service diversity is improved, but the transmission reliability decreases due to inability to support simultaneous transmission of two transmission blocks
Solution Approach 1:
The patent applies local quality by assigning different resource allocation modes to different frequency bands and time periods rather than using a single mode system-wide. Each frequency band and time slot can have its own optimized resource allocation mode, allowing the terminal to maintain reliable single-transmission-block operation within each local context while achieving diverse service support across the entire system through spatial and temporal differentiation.
3Productivity
If the network configures multiple resource allocation modes for the terminal, then the productivity and service capability are improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements self-service by enabling the terminal to automatically determine and switch between resource allocation modes based on pre-configured rules and current operating conditions. The terminal autonomously selects the appropriate mode without requiring manual configuration or complex user decisions, thereby maintaining high service capability while significantly improving ease of operation. The system serves itself by making intelligent mode selections based on the configured parameters and current frequency band usage.
