GNSS Assistance Reporting for RRC Data and Measurement Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in performing Global Navigation Satellite System (GNSS) measurements by terminal devices in Radio Resource Control (RRC) connected states due to simultaneous data reception limitations, leading to data loss and reduced information transmission reliability.
Innovation Solution
The terminal device triggers the reporting of GNSS assistance information, allowing the network device to coordinate appropriate GNSS measurements, thereby reducing data loss during transmission and enhancing information transmission reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device performs GNSS measurement in RRC connected state, then position information can be obtained, but data reception is limited causing data loss
Solution Approach 1:
The terminal device triggers reporting of GNSS assistance information before performing measurements, and the network device configures measurement gaps in advance. This preliminary configuration ensures that data transmission and GNSS measurements are coordinated from the outset, preventing data loss before it occurs.
Solution Approach 2:
The system dynamically adjusts measurement configuration based on terminal device state. The network device receives GNSS assistance information, determines appropriate measurement configurations, and configures measurement gaps dynamically. This allows the system to adapt measurement timing to current data transmission conditions, ensuring both measurement accuracy and data reliability.
2Measurement precision
If the terminal device performs GNSS measurement, then position information is obtained, but simultaneous data reception is limited
Solution Approach 1:
The communication channel is segmented into measurement gaps and data transmission periods. The network device configures specific time intervals (measurement gaps) dedicated to GNSS measurements, while other periods are allocated for data transmission. This segmentation eliminates interference between measurements and data reception, ensuring both position accuracy and data integrity.
Solution Approach 2:
The network device acts as an intermediary that coordinates between data transmission requirements and GNSS measurement needs. It receives GNSS assistance information from the terminal, determines appropriate measurement configurations, and schedules measurement gaps accordingly. This intermediary coordination ensures that measurements and data transmission occur at optimal times without conflict.
3Reliability
If the terminal device reports GNSS assistance information, then measurement coordination improves, but communication overhead increases
Solution Approach 1:
The terminal device reports GNSS assistance information selectively rather than continuously. Reporting is triggered by specific conditions such as changes in assistance information or when measurement configuration is needed. This partial action approach provides sufficient coordination information to the network device while minimizing unnecessary communication overhead.
