Sidelink Transmission Priority for Overlapping Ranging Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, terminals cannot simultaneously send and receive data or reference signals, leading to failures in relative positioning due to overlapping resource locations, which affects the reliability of relative positioning between terminals.
Innovation Solution
A method for determining transmission operations on overlapping resource locations based on the priorities of data and ranging signals, allowing terminals to prioritize transmissions based on priority thresholds to avoid resource conflicts and ensure reliable relative positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals use sidelink communication for direct data transmission, then communication efficiency is improved, but terminals cannot simultaneously send and receive ranging signals leading to positioning failures
Solution Approach 1:
The patent implements dynamic resource allocation where the terminal adaptively switches between transmission and reception modes based on the timing of sidelink data and ranging signals. The terminal determines whether to send or receive at each time slot based on real-time resource availability and signal timing, making the system flexible rather than fixed in its inability to handle overlapping resources.
Solution Approach 2:
The patent segments the time-frequency resources into distinct transmission opportunities for sidelink data and ranging signals. By dividing the resource space and assigning specific time slots for each function, the terminal can properly handle ranging signal reception at designated moments without conflict, while maintaining continuous sidelink communication capability in other resource segments.
2Adaptability or versatility
If terminals multiplex uplink cellular network resources for sidelink transmission, then resource utilization is improved, but terminals cannot perform uplink data sending and sidelink transmission simultaneously
Solution Approach 1:
The patent employs periodic time-division multiplexing where the terminal alternates between uplink cellular transmission and sidelink transmission in regular time intervals. This periodic switching allows the terminal to utilize both communication modes by assigning specific time slots for each function, achieving resource multiplexing while maintaining the ability to perform both uplink and sidelink operations sequentially.
