PC5 Sidelink Unicast Link Establishment for Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently establishing and managing unicast links for sidelink positioning in 5G networks, particularly in supporting large data communication demands and ensuring reliable, secure data transfer.
Innovation Solution
The method involves a first User Equipment (UE) initiating a procedure to establish a PC5 connection with a second UE, sending a first PC5 message that includes sidelink positioning or ranging related information, and subsequently managing the unicast link through security establishment and quality of service (QoS) parameter configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If unicast link establishment procedure is initiated for sidelink positioning, then positioning accuracy and data transfer reliability are improved, but connection establishment time and signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring QoS parameters and security settings before the actual data transfer begins. The network pre-establishes the unicast link with all necessary positioning parameters, so when positioning data needs to be transferred, the link is already ready, reducing establishment time while maintaining reliability.
2Reliability
If security establishment and QoS parameter configuration are performed for unicast link, then data transfer security and service quality are improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent implements self-service by enabling UEs to autonomously configure their own security parameters and QoS settings based on pre-defined policies and network-provided templates. This reduces the processing burden on the network and simplifies device complexity while maintaining high security and service quality standards for positioning data transfer.

AI summary
A method and device for a first User Equipment (UE) are disclosed. In one embodiment, the first UE initiates a procedure for establishing a PC5 connection with a second UE. Furthermore, the first UE sends a first PC5 message to the second UE for request of establishment of the PC5 connection in the procedure, wherein the first PC5 message includes a first Sidelink (SL) positioning or ranging related information.
