Terminal Positioning Using Differential Signal Quality Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of large volumes of signal quality data from terminal devices to network devices can lead to communication congestion and poor real-time performance in positioning systems, especially when a large number of devices are connected.
Innovation Solution
The terminal device processes first and second signal qualities to determine differential signal quality, reducing the data transmitted by calculating differences between signal qualities received from different network devices, thereby reducing the amount of data sent to the location server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminal devices send complete signal quality data to network devices for positioning, then positioning accuracy is maintained, but communication congestion occurs and real-time performance deteriorates
Solution Approach 1:
The patent extracts only the essential positioning information (differential signal quality) from the complete signal quality data. Instead of transmitting all raw signal quality measurements, the terminal device calculates the difference between reference signal quality and neighboring cell signal qualities, extracting only the differential values that are sufficient for positioning while discarding redundant information.
Solution Approach 2:
The patent transforms the signal quality parameters by calculating differential values. The complete signal quality data (RSRP, RSRQ, RSSI for each cell) is converted into differential signal quality parameters (difference between reference and neighboring cell measurements), changing the parameter representation to reduce data volume while preserving positioning capability.
2Loss of information
If terminal devices send complete signal quality data to network devices, then positioning information completeness is maintained, but communication congestion and packet loss increase
Solution Approach 1:
The patent extracts only the essential positioning information (differential signal quality) from the complete signal quality data. Instead of transmitting all raw signal quality measurements, the terminal device calculates the difference between reference signal quality and neighboring cell signal qualities, extracting only the differential values that are sufficient for positioning while discarding redundant information.
Solution Approach 2:
The patent applies partial action by transmitting only a subset of the available signal quality information - specifically the differential values rather than complete measurements. This partial transmission is sufficient for positioning purposes while significantly reducing the data volume and avoiding communication congestion.

AI summary
A method for communication, a terminal device, and a network device are provided. The method includes: a terminal device obtaining first signal quality of a first signal and second signal quality of a second signal, and the terminal device determining first differential signal quality based on the first signal quality and the second signal quality. The first signal and the second signal are respectively sent or received by different network devices, and the first differential signal quality is used to implement positioning of the terminal device. The terminal device may process the first signal quality and the second signal quality to obtain the first differential signal quality. That is, based on the processing of the terminal device, one piece of data may be obtained based on the two pieces of data. Therefore, in the subsequent transmission process, transmission of at least one piece of data may be reduced, thereby reducing the amount of data that flows into a location server and reducing communication and calculation pressure of the location server. In addition, because the amount of transmitted data is reduced, the present disclosure may further reduce packet loss during data transmission.
