Terminal Spatial Relationship Determination via QoS Parameter Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G new radio (NR) networks, there is no user equipment capable of positioning other user equipment, leading to challenges in determining relative spatial relationships between terminals due to differing quality of service requirements for spatial positioning compared to regular communication processes.
Innovation Solution
An information sending method and relationship determination method where a first terminal sends quality of service information to a second terminal to determine their relative spatial relationship, including parameters like precision, response time, and distance limits, allowing the second terminal to configure and measure signals accordingly to meet the required quality of service for spatial positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user equipment performs positioning using existing communication protocols, then regular communication quality of service is maintained, but spatial positioning quality of service requirements cannot be met
Solution Approach 1:
The patent applies local quality by differentiating quality of service requirements for spatial positioning from regular communication processes. The first terminal sends specific quality of service information (including precision requirements, response time, and distance limits) to the second terminal, enabling localized optimization of positioning measurements without affecting overall communication quality.
Solution Approach 2:
The patent implements parameter changes by transmitting quality of service parameters (precision, response time, distance limits) that dynamically adjust the positioning process. The second terminal uses these parameters to configure measurement signals and determine spatial relationships, transforming fixed communication protocols into adaptive positioning-aware communication.
2Adaptability or versatility
If no user equipment is equipped with positioning capability, then device complexity is reduced, but the ability to determine relative spatial relationships is lost
Solution Approach 1:
The patent applies self-service by enabling terminals to determine spatial relationships using existing communication capabilities. The first terminal sends quality of service information and the second terminal uses this information to configure measurements and determine spatial relationships, allowing the system to serve its own positioning needs without external positioning infrastructure.
Solution Approach 2:
The patent implements universality by using existing communication protocols and signals for dual purposes: regular communication and spatial positioning. The same communication channel and signal processing capabilities serve both communication and positioning functions, avoiding the need for dedicated positioning hardware.
3Measurement precision
If quality of service information is sent for spatial positioning, then positioning accuracy is improved, but communication overhead increases
Solution Approach 1:
The patent applies taking out by extracting only the essential quality of service parameters needed for positioning (precision requirements, response time, distance limits) from the overall communication protocol. This selective extraction minimizes the amount of additional information exchanged while providing sufficient guidance for accurate spatial relationship determination.
