Positioning Request Preference Order for NR Network Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) networks, User Equipment (UE) initiated positioning requests often face rejection due to resource constraints, leading to increased latency and inefficiency in positioning operations.
Innovation Solution
A node apparatus is configured to transmit information about multiple configurations for signals that enable positioning, along with an order of preference, to optimize the use of network resources and improve the likelihood of successful positioning requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network accepts all UE-initiated positioning requests, then positioning service availability is improved, but network resource consumption increases
Solution Approach 1:
The network performs preliminary actions by proactively announcing multiple positioning configurations and their preferences before UE requests are processed. This allows UEs to make informed requests and enables the network to prepare resource allocation in advance, reducing the need for rejection and retransmission while optimizing resource usage.
Solution Approach 2:
The invention changes the parameter of configuration announcement by providing multiple positioning configurations with different parameters (e.g., different signal types, frequency ranges, time resources) and their preference orders. This allows flexible adaptation to different UE capabilities and network conditions, improving service availability while optimizing resource consumption through selective configuration usage.
2Loss of time
If the network processes positioning requests without pre-announcing configurations, then network operation simplicity is maintained, but positioning latency increases
Solution Approach 1:
The network performs preliminary action by announcing multiple positioning configurations and their preferences in advance through system information or dedicated signaling. This enables UEs to immediately select appropriate configurations when initiating positioning requests, significantly reducing positioning latency without requiring complex real-time negotiation or configuration establishment procedures.
3Reliability
If multiple positioning configurations are announced with preference orders, then positioning request success rate is improved, but information transmission overhead increases
Solution Approach 1:
The invention efficiently manages information overhead by changing parameters of the configuration announcements - providing multiple configurations with different signal types, frequency ranges, and time resources along with preference orders. The information is structured to convey essential parameters concisely, allowing UEs to understand available options and make informed requests without excessive signaling overhead.
