Wireless Device Consecutive Resource Assignment for Sidelink Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in sidelink communication, particularly in allocating resources for data transmission based on priority levels and reservation intervals, leading to suboptimal transmission sequences and potential delays.
Innovation Solution
Implementing a method where wireless devices group data transmissions based on priority levels and reservation intervals, assigning consecutive resources with the same priority value to ensure higher priority data is transmitted before lower priority data, optimizing resource allocation in sidelink communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If consecutive resources are allocated for data transmission without priority-based grouping, then resource allocation simplicity is maintained, but transmission efficiency and delay performance deteriorate
Solution Approach 1:
The patent segments consecutive resources into multiple groups based on priority levels and reservation intervals. Each group contains resources allocated for data with specific priority characteristics, allowing the system to manage different priority traffic separately while maintaining overall resource allocation structure.
Solution Approach 2:
The patent performs preliminary grouping of resources by priority level and reservation interval before actual data transmission. This advance organization ensures that when data arrives, the system can quickly assign it to the appropriate priority group without complex real-time decisions, improving transmission efficiency while keeping allocation rules simple.
2Loss of time
If data is transmitted without priority-based resource assignment, then allocation process is simple, but transmission delay increases for high-priority data
Solution Approach 1:
The patent applies different allocation rules to different portions of resources based on local requirements. High-priority data receives resources from specific priority groups with shorter reservation intervals, while lower-priority data uses other groups. This localized differentiation reduces delay for critical data without complicating the overall system with uniform complexity.
Solution Approach 2:
The patent changes the parameter of reservation interval based on priority level. High-priority data is assigned shorter reservation intervals allowing faster access to consecutive resources, while lower-priority data uses longer intervals. This parameter differentiation directly addresses transmission delay without requiring complex scheduling algorithms.
3Reliability
If consecutive resources are assigned without priority consideration, then resource management is straightforward, but network performance and reliability deteriorate
Solution Approach 1:
The patent segments resources into priority-based groups to ensure reliable transmission of critical data. By separating high-priority traffic into dedicated resource groups with appropriate reservation intervals, the system guarantees transmission reliability for important communications while maintaining straightforward management through clear allocation rules.
Solution Approach 2:
The patent establishes preliminary resource reservations based on priority levels and expected transmission patterns. This advance preparation ensures that when high-priority data needs transmission, resources are already allocated and ready, improving reliability without requiring complex real-time resource management during actual transmission.

AI summary
A wireless device may communicate with one or more other wireless devices. The wireless device-to-wireless device communication may use consecutive resources, such as in a multiple consecutive slot transmission. Consecutive resources may be assigned a same priority value and/or a same resource interval and data transmitted in the consecutive resources may be associated with the same priority value and/or the same resource interval.
