SRS Request Messaging for Low-Latency Wireless Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning processes in communication technologies require multiple interactions between the core network and base stations, leading to delays exceeding 50 ms, which do not meet the requirements for low latency positioning.
Innovation Solution
A method where the core network sends a combined position information and measurement result request to the base station in a single message, allowing the base station to determine SRS configuration and send a single response message with the measurement result, reducing the number of interactions and simplifying the positioning flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multiple interactions between core network and base stations are used for positioning, then positioning accuracy can be maintained, but positioning time exceeds 50 ms causing high delay
Solution Approach 1:
The patent combines multiple positioning-related interactions into a single message exchange. The core network sends a first message containing both position information request and measurement result request to the base station, and receives a second message containing both SRS configuration information and measurement result in one response. This merging of multiple interactions into single message exchanges reduces positioning time from over 50 ms to under 10 ms while maintaining positioning accuracy.
2Productivity
If multiple separate requests are sent for position information and measurement results, then information completeness is ensured, but communication steps increase causing positioning delay
Solution Approach 1:
The patent implements multi-functionality in the message structure. The first message serves multiple purposes by simultaneously requesting both position information and measurement results from the base station. The second message similarly serves multiple functions by providing both SRS configuration information and measurement results in a single response. This universal approach allows one message to perform multiple communication tasks, thereby improving positioning efficiency and reducing communication time.

AI summary
A request sending method, electronic device and computer readable storage medium that improves performance of a wireless communication network. The wireless performance is improved by sending a first message to a base station, where the first message includes a position information request and a measurement result request, the position information request is used to request the base station to determine sounding reference signal (SRS) configuration information of a terminal, and the measurement result request is used to request the base station to send a measurement result for an SRS sent by the terminal to a core network; receiving a second message from the base station, where the second message includes the measurement result.
