Wireless Paging and Positioning Timing in RRC Idle Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coordination of positioning measurement and paging detection in terminal devices in RRC idle or inactive states is inefficient, leading to increased power consumption and communication delays due to frequent state transitions and synchronization requirements.
Innovation Solution
A method is provided to associate time periods for positioning measurement or SRS transmission with paging detection, ensuring they are either partially or fully overlapping or adjacent, with a defined threshold to minimize synchronization losses, and a mechanism to handle conflicts between positioning measurement and PEI detection.

Engineering Contradiction Analysis
1Reliability
If the terminal device performs positioning measurement and paging detection separately with frequent state transitions, then positioning accuracy and paging reliability are maintained, but power consumption increases and communication delays occur
Solution Approach 1:
The patent combines positioning measurement and paging detection into a unified time resource management framework. By associating positioning time periods with paging time periods (making them partially or fully overlapping or adjacent), the terminal device can perform both operations in a coordinated manner, reducing the need for frequent state transitions and lowering power consumption while maintaining reliability of both functions
Solution Approach 2:
The patent introduces dynamic time period association mechanisms where the positioning time period and paging time period can be flexibly configured based on terminal state (RRC idle or inactive). The system can adjust the timing relationships dynamically, allowing the terminal to transition between operations efficiently without rigid fixed schedules, thereby reducing energy consumption while maintaining operational reliability
2Reliability
If the terminal device performs positioning measurement and paging detection separately with frequent state transitions, then positioning accuracy and paging reliability are maintained, but communication delays increase
Solution Approach 1:
The patent merges positioning measurement and paging detection into coordinated time periods, allowing the terminal device to perform both operations without frequent state transitions. This integration eliminates the time loss associated with repeated transitions between idle and connected states, reducing communication delays while maintaining the reliability of both positioning and paging functions
Solution Approach 2:
The patent enables preliminary configuration of time period associations between positioning and paging operations. By pre-establishing the timing relationships and associations in the RRC idle or inactive states, the terminal device is prepared to execute both operations efficiently without experiencing delays from ad-hoc state transitions, thus reducing communication delays while preserving reliability
3Ease of operation
If positioning time period and paging time period are separated without association, then operation simplicity is maintained, but synchronization losses increase and system efficiency decreases
Solution Approach 1:
The patent implements dynamic time period association where the relationship between positioning and paging time periods can be flexibly configured based on terminal state and operational requirements. This dynamic approach maintains operational simplicity through standardized procedures while significantly improving system efficiency by reducing synchronization losses and enabling better resource utilization through coordinated time management
