Timing Advance Transmission for Low-Overhead Wireless Positioning

Solution Overview

Problem

Existing wireless communication systems face increased power consumption and signaling overheads due to interactive response processes during wireless signal transmission, particularly in scenarios requiring location information from terminal devices, which degrades performance in IoT and mMTC applications.

Innovation Solution

A method where a first communication node determines a target sending time based on a pre-stored Timing Advance (TA) and sends target information including TA and identification information to a second communication node, eliminating the need for interactive processes and reducing signaling overheads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If interactive response processes are used for wireless signal transmission, then communication reliability is improved, but signaling overheads and power consumption increase

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidsignaling overheads

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-storing the Timing Advance (TA) value in the terminal device before the actual communication occurs. This pre-stored TA is then directly used to determine the target sending time for transmitting location information, eliminating the need for interactive TA acquisition processes during communication, thereby reducing signaling overheads while maintaining communication reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts the TA acquisition step from the interactive communication process. Instead of obtaining TA through back-and-forth signaling during communication, the solution separates this function by using pre-stored TA values, thereby extracting the complex interactive process and replacing it with a simpler direct transmission approach

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 1:

The patent incorporates feedback mechanisms where the network side validates and adjusts the pre-stored TA values to ensure timing accuracy. The network receives the location information at the calculated target sending time and can provide feedback to correct any timing deviations, thereby maintaining measurement precision while reducing signaling overheads through the pre-stored TA approach
