Sidelink Positioning Reference Signal Resource Request Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently requesting and allocating resources for sidelink positioning reference signals, which are crucial for accurate positioning in environments like indoor factories and vehicle-to-everything (V2X) communications, where high accuracy and low latency are required.
Innovation Solution
The method involves transmitting a request for sidelink positioning reference signal resources, receiving a response, and transmitting the sidelink positioning reference signal along with a report containing estimated positioning information, using a combination of network units and remote units equipped with processors, transmitters, and receivers, and configuring resource pools for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional resource allocation methods are used for sidelink positioning reference signals, then device complexity is reduced, but positioning accuracy and timing precision deteriorate
Solution Approach 1:
The network configures and pre-allocates sidelink positioning reference signal resources before actual positioning operations are needed. This includes pre-defining resource pools, time-frequency structures, and transmission parameters, allowing UEs to perform accurate positioning measurements without complex real-time resource negotiation
Solution Approach 2:
The network acts as an intermediary that manages and coordinates sidelink positioning resources. It provides centralized configuration and control, simplifying the complexity by having a single entity manage resource allocation rather than requiring complex peer-to-peer negotiation between UEs
2Speed
If dynamic resource allocation is implemented for sidelink positioning reference signals, then positioning speed and responsiveness improve, but system complexity increases
Solution Approach 1:
The system implements dynamic resource allocation where the network can adjust sidelink positioning reference signal resources based on real-time positioning requirements, traffic conditions, and UE demands. This allows rapid response to positioning needs while the network manages the complexity of dynamic adjustments
3Reliability
If dedicated resources are allocated for sidelink positioning reference signals, then positioning reliability improves, but resource utilization efficiency deteriorates
Solution Approach 1:
The system creates dedicated sidelink positioning reference signal resources that can serve multiple positioning scenarios and multiple UEs simultaneously. These universal positioning resources provide reliable dedicated allocation while being efficiently shared across different positioning operations, improving both reliability and resource utilization
