LMF Positioning Selection Between Bandwidth Aggregation and Single Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bandwidth aggregation positioning in 3GPP-based communications are inefficient.
Innovation Solution
A method for a Location Management Function (LMF) to determine whether to perform positioning using bandwidth-aggregated or single-carrier positioning based on the Transmission and Reception Point (TEG) of a base station and a UE, and a device to implement this method.

Engineering Contradiction Analysis
1Measurement precision
If bandwidth aggregation positioning is implemented, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic selection between bandwidth aggregation positioning and single-carrier positioning based on TEG conditions. The LMF determines whether to activate bandwidth aggregation mode by evaluating TEG parameters, allowing the system to adaptively switch between positioning methods to balance accuracy requirements with system complexity and resource availability.
Solution Approach 2:
The patent changes the operational parameters of the positioning system by introducing TEG (Transmission and Reception Point) as a decision parameter. By monitoring TEG values and comparing them against thresholds, the system dynamically adjusts positioning parameters such as bandwidth aggregation configuration, enabling accurate positioning while managing system complexity through parameter-based control.
2Measurement precision
If bandwidth aggregation positioning is used, then positioning accuracy is enhanced, but signaling overhead increases
Solution Approach 1:
The patent performs preliminary evaluation of TEG conditions before activating bandwidth aggregation positioning. The LMF assesses TEG parameters in advance to determine whether bandwidth aggregation is necessary, thereby avoiding unnecessary signaling exchanges and reducing overhead while ensuring positioning accuracy is maintained when conditions warrant it.
Solution Approach 2:
The system implements self-service by having the LMF autonomously determine whether bandwidth aggregation positioning should be activated based on received TEG information from the UE and base station. This self-determination mechanism reduces signaling overhead by eliminating the need for extensive negotiation and configuration messages between network entities.

AI summary
One disclosure of the present specification provides a method by which an LMF performs communication. The method may comprise the steps of: receiving, from a base station, a Tx TEG of the base station; receiving a TEG related to UE from the UE, and determining, on the basis of at least one of the Tx TEG of the base station and the TEG related to the UE, which method, between bandwidth aggregation positioning or single carrier positioning, to use to perform positioning.
