Base Station Measurement Gap Control for Faster Terminal Positioning

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The latency in positioning processes is increased due to the need for a communication terminal to request a measurement gap configuration from the serving base station after initiating positioning, which delays the measurement of positioning signals from neighboring base stations.

Innovation Solution

A communication system where 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 terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the communication terminal requests measurement gap configuration from the serving base station after initiating positioning, then the positioning process can be completed with terminal-initiated control, but the positioning latency is increased

Engineering Contradiction:

Improveterminal-initiated controlVSAvoidpositioning latency

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The serving base station performs preliminary action by proactively configuring the measurement gap before the terminal requests it. The base station determines positioning requirements and configures measurement gaps in advance, eliminating the waiting time that would occur if the terminal had to request configuration after initiating positioning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent inverts the traditional control flow by having the base station initiate measurement gap configuration instead of the terminal requesting it. This role reversal allows the network side to optimize positioning performance by proactively managing measurement resources based on overall system state and positioning requirements.

Inventive Principle:

Principle #13The other way round (Inversion)

2Loss of time

If the serving base station proactively configures measurement gap without terminal request, then positioning latency is reduced, but the base station complexity increases

Engineering Contradiction:

Improvepositioning latencyVSAvoidbase station complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The serving base station performs self-service by autonomously determining positioning requirements and configuring measurement gaps without requiring terminal requests. The base station uses its own capabilities to assess positioning needs and proactively allocates measurement resources, reducing dependency on terminal-initiated control sequences.

Inventive Principle:

Principle #25Self-service

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.
