One-Way Positioning Using MIB Time Reference for Low Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in providing low-latency and high-capacity positioning methods, especially with the increasing demand for 5G technology, which requires lower data latency and the ability to connect a large number of user equipment (UEs) to a single base station, while existing positioning techniques are limited by the need for multiple references and two-way communication.
Innovation Solution
A method for performing positioning in a wireless communication system using a one-way positioning technique, where a user equipment (UE) receives master information block (MIB) information from a base station, sets a time reference, measures a positioning-related signal, and calculates distance and direction information based on the signal, allowing for positioning with a single reference cell and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional two-way positioning techniques are used, then positioning accuracy can be achieved, but latency increases and system complexity increases due to requiring multiple references and round-trip communication
Solution Approach 1:
The patent inverts the traditional two-way positioning approach by implementing a one-way positioning technique where the base station transmits positioning signals and the UE calculates its position based on received signal characteristics, eliminating the need for round-trip communication and multiple references while reducing latency and system complexity
2Measurement precision
If multiple reference cells are used for positioning, then positioning accuracy improves, but the number of required signals and processing complexity increase
Solution Approach 1:
The patent extracts the essential positioning function from the complex multi-reference system by using a single reference cell and deriving position information from one-way signal measurements, maintaining sufficient accuracy while significantly reducing the number of required reference signals and processing complexity
3Productivity
If 5G technology requirements are met with higher connectivity density, then network capacity increases, but positioning becomes more challenging due to increased UE density and resource constraints
Solution Approach 1:
The patent makes the positioning system universal and scalable for 5G networks by implementing a lightweight one-way positioning method that can handle high UE density efficiently, using minimal signaling resources and enabling simultaneous positioning of multiple UEs without proportionally increasing system complexity

AI summary
According to an embodiment of the present specification, a method for measuring a position by a terminal in a wireless communication system can be provided. The method for measuring a position by a terminal may comprise the steps of: receiving MIB information from a base station by a terminal; setting a reference for time on the basis of the received MIB information; receiving a positioning-related signal from the base station by the terminal; measuring the positioning-related signal; and acquiring distance information and orientation information of the terminal on the basis of the measured positioning-related signal. The terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
