UE GNSS Position Reporting During DRX Inactive Periods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT terminals cannot simultaneously support GNSS reception and LTE transmission/reception, leading to outdated GNSS positions and reduced system performance due to the need for separate measurement gaps, which affect system efficiency.
Innovation Solution
The UE reports GNSS position and validity period during connected-state DRX inactive periods, allowing autonomous GNSS measurements without network configuration, and the network device adjusts configurations to avoid conflicts and improve system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE performs GNSS measurements during connected-state DRX inactive periods, then the GNSS position update efficiency is improved, but the system may experience conflicts between GNSS reception and LTE transmission/reception
Solution Approach 1:
The network device pre-configures measurement gaps and informs the UE of available GNSS measurement opportunities before the UE actually performs measurements. This allows the UE to plan its GNSS reception in advance during DRX inactive periods, ensuring it only measures when no LTE transmission/reception is scheduled, thus avoiding conflicts while maintaining efficient position updates
Solution Approach 2:
The UE reports its GNSS measurement status, capability, and position information to the network device. The network device uses this feedback to adjust scheduling decisions, configure appropriate measurement gaps, and coordinate between LTE and GNSS operations, ensuring reliable system operation while enabling efficient GNSS updates
2Loss of time
If the UE autonomously performs GNSS measurements without network configuration, then the measurement time is reduced, but the coordination between network and UE is weakened
Solution Approach 1:
The UE performs autonomous GNSS measurements during pre-configured measurement gaps without requiring real-time network commands for each measurement. The network provides partial configuration (measurement gap patterns, DRX parameters) in advance, and the UE independently executes measurements during inactive periods, reducing measurement time while maintaining adequate coordination through initial configuration and periodic reporting

AI summary
The embodiments of the present disclosure relate to the technical field of communications, and disclose measurement methods and apparatuses, and a computer-readable storage medium. A measurement method applied to a user equipment (UE) side comprises: determining a global navigation satellite system (GNSS) position; and reporting to a network device first indication information, the first indication information being used for indicating a GNSS validity period of the GNSS position, or being used for indicating the GNSS position. In the embodiments of the present disclosure, after determining the GNSS position, a UE reports to the network device the information used for indicating the determined GNSS position, or used for indicating the GNSS validity period of the determined GNSS position, so as to inform the network device of the GNSS position acquired by the UE, aiding in subsequent operations so as to improve system performance.
