Serving Base Station Gap Configuration for Low-Latency UE Positioning

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The latency in positioning operations for communication terminals is increased due to the need for the user equipment (UE) to request a measurement gap configuration from the serving base station, which delays the transmission and reception of positioning signals from neighboring base stations.

Innovation Solution

The serving base station proactively configures a measurement gap for the communication terminal to measure positioning signals from neighboring base stations without a request from the UE, thereby reducing latency in positioning operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the UE requests the serving base station to configure a measurement gap, then the positioning measurement can be performed, but the positioning latency is increased

Engineering Contradiction:

Improvepositioning measurementVSAvoidpositioning latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The serving base station proactively configures the measurement gap for the UE before the UE needs to perform positioning measurements, eliminating the need for UE-initiated requests and reducing positioning latency. This preliminary configuration action resolves the contradiction by preparing the measurement gap in advance.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the UE autonomously determines measurement gap configuration, then the positioning process is faster, but the system control and coordination is reduced

Engineering Contradiction:

Improvepositioning speedVSAvoidsystem control

Core Design Contradiction:

ProductivityVSExtent of automation

Solution Approach 1:

The serving base station acts as an intermediary that automatically configures measurement gaps based on positioning requirements, balancing autonomous action with system control. This intermediary approach maintains system coordination while enabling fast positioning execution.

AI summary

A communication system includes a communication terminal, and a serving base station of the communication terminal. The serving base station notifies the communication terminal of an instruction to configure a measurement gap for the communication terminal to measure a positioning signal transmitted from at least one neighboring base station in order to measure a position of the communication terminal, without a request from the communication terminal (Step ST1417).
