Base Station Resource Scheduling for Sidelink Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, resource collisions occur when multiple terminals randomly select transmission resources, leading to transmission conflicts and reduced channel communication quality during relative positioning between terminals.
Innovation Solution
A method and apparatus for determining transmission resources of a relative positioning signal, where a base station sends resource configuration information to terminals, allowing them to select or receive specific transmission resources, thereby mitigating resource collisions through unified resource scheduling and collision avoidance mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple terminals randomly select transmission resources for relative positioning signals, then terminals can autonomously perform positioning without network coordination, but resource collisions occur leading to transmission conflicts and reduced channel communication quality
Solution Approach 1:
The base station acts as an intermediary that coordinates resource allocation for relative positioning signals. Instead of terminals randomly selecting resources independently, the base station receives positioning requirements from terminals and allocates specific transmission resources, thereby preventing collisions while maintaining autonomous terminal operation capability
Solution Approach 2:
The base station performs preliminary resource allocation before terminals transmit relative positioning signals. By pre-assigning specific time-frequency resources to each terminal based on their positioning needs, the system avoids resource conflicts during actual transmission while maintaining operational autonomy
2Reliability
If base station configures specific transmission resources for each terminal, then resource collisions are avoided and channel communication quality improves, but system complexity increases due to unified resource scheduling
Solution Approach 1:
The base station utilizes existing resource management frameworks and signaling mechanisms to configure transmission resources for relative positioning signals. By leveraging universal resource allocation procedures already present in the system, the base station can manage positioning resources without significantly increasing overall system complexity
Solution Approach 2:
The base station applies differentiated resource configuration specifically for relative positioning signals rather than redesigning the entire resource management system. By focusing resource scheduling efforts only on positioning-related transmissions, the system achieves improved reliability while minimizing additional complexity
3Adaptability or versatility
If terminals use sidelink communication for relative positioning, then direct terminal-to-terminal positioning is enabled, but resource collisions occur when multiple terminals select transmission resources randomly
Solution Approach 1:
The base station serves as a coordinating intermediary that manages sidelink resource allocation for relative positioning. It receives positioning requests from terminals and assigns specific transmission resources, thereby enabling direct terminal communication while preventing resource collisions through centralized coordination
Solution Approach 2:
The base station segments the sidelink resource pool into dedicated transmission resources for different terminals performing relative positioning. By dividing available resources into distinct allocations for each terminal pair, the system enables direct communication capability while eliminating interference from random resource selection
