PRS Measurement Priority Configuration Without Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication technologies, the existing methods for configuring positioning reference signals (PRS) lead to measurement time delays and inefficiencies due to reliance on measurement gaps, which affect communication efficiency.
Innovation Solution
A method where a terminal, access network device, and location server configure information to prioritize PRS measurements, allowing the terminal to measure PRS without relying on measurement gaps by receiving configuration information indicating a target priority, thereby reducing measurement delays and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal performs PRS measurement based on measurement gap configuration, then the positioning measurement can be completed, but measurement time delays occur and communication efficiency deteriorates
Solution Approach 1:
The patent extracts the constraint of measurement gap configuration from the PRS measurement process. By introducing a new indication parameter that explicitly marks certain PRS resources as not requiring measurement gap, the patent separates the measurement requirement from the traditional measurement gap mechanism, allowing terminals to perform measurements without the time loss associated with measurement gaps.
Solution Approach 2:
The patent changes the parameter configuration by introducing a new indication parameter (e.g., a binary flag or priority indicator) that modifies the measurement behavior. When this parameter indicates that measurement gap is not required, the terminal adjusts its measurement process accordingly, transitioning from gap-based measurement to continuous measurement mode, thereby reducing measurement time delay while maintaining measurement accuracy.
2Measurement precision
If the terminal performs PRS measurement based on measurement gap configuration, then positioning can be achieved, but communication efficiency deteriorates
Solution Approach 1:
The patent removes the measurement gap constraint from the PRS measurement process by introducing an indication parameter. This extraction allows the terminal to perform PRS measurements during normal communication time slots rather than during dedicated measurement gaps, thereby maintaining positioning accuracy while improving communication efficiency by eliminating the interruption to normal data transmission.
Solution Approach 2:
The patent implements preliminary action by configuring the indication parameter in advance through RRC signaling or other control channels. This allows the terminal to know beforehand whether measurement gap is required for specific PRS resources, enabling the terminal to plan its measurement schedule optimally and avoid last-minute scheduling conflicts that would reduce communication efficiency.

AI summary
A method for configuring information, performed by a terminal device, including: receiving first configuration information, in which, the first configuration information indicates that a priority of a positioning reference signal is a target priority, and a positioning reference signal with the target priority is a positioning reference signal that the terminal does not perform measurement based on a measurement gap.
