Sidelink Positioning QoS Segmentation for Reliable V2X Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently support multiple Quality of Service (QoS) classes in sidelink positioning, particularly in scenarios involving vehicle-to-everything (V2X) communication, which requires improved mobile broadband, massive machine type communication, and ultra-reliable low latency communication.
Innovation Solution
A method and apparatus for a User Equipment (UE) to receive and transmit location information messages based on multiple QoS classes, including primary, intermediate, and minimum QoS classes, with sequential location measurements to ensure successful transmission of location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single QoS class is used for location information transmission, then the system complexity is reduced, but the ability to support diverse service requirements (improved mobile broadband, massive MTC, URLLC) is degraded
Solution Approach 1:
The patent segments location information transmission into multiple QoS classes (first QoS class for high reliability/low latency services like URLLC, second QoS class for other services). This segmentation allows the system to handle different service requirements separately, improving adaptability while managing complexity through structured classification.
Solution Approach 2:
The patent implements dynamic QoS class selection based on service requirements. The system can adaptively choose which QoS class to use for transmitting location information depending on the specific service type and requirements, making the system flexible and adaptable to diverse communication scenarios.
2Reliability
If location information is transmitted for multiple QoS classes simultaneously, then service coverage is improved, but transmission reliability for critical services may be degraded
Solution Approach 1:
The patent performs location measurement for the first QoS class (high reliability requirement) before transmitting location information for other QoS classes. This preliminary action ensures that critical services receive location information with guaranteed reliability first, while other services can use the same measurement results or perform additional measurements if needed.
Solution Approach 2:
The patent applies different quality requirements to different QoS classes. The first QoS class receives location information with high reliability guarantees (suitable for URLLC), while the second QoS class can accept lower reliability levels. This local quality differentiation optimizes overall system performance by matching service requirements with appropriate quality levels.

AI summary
ABSTRACT: The present disclosure relates to a method by which a user equipment (UE) performs sidelink positioning in a wireless communication system. Particularly, the method comprises the steps of: receiving a location information request message including information regarding a plurality of quality of service (QoS) classes; and transmitting a location information message in response to the location information request message, wherein the location information message includes information regarding one QoS class from among the plurality of QoS classes and location information related to the one QoS class.
