Terminal Delay Difference Reporting for Satellite Measurement Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, the large signal propagation delay difference between network devices in different cells leads to increased energy consumption and affects user experience, particularly in satellite communications where the large field of view results in significant propagation delay differences.
Innovation Solution
A communication method where a terminal sends first indication information to a network device to indicate the delay difference between propagation delays to different cells, allowing the network device to adjust measurement configuration information, such as SMTC and measurement gap durations, to compensate for these delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement information is configured to compensate for propagation delay differences between network devices in different cells, then measurement accuracy is improved, but energy consumption increases
Solution Approach 1:
The terminal device performs preliminary calculation of propagation delays to multiple network devices and reports the delay difference information to the network device before actual measurement occurs. This preliminary action allows the network device to pre-configure appropriate measurement parameters, avoiding the need for continuous high-energy measurement attempts and enabling more efficient measurement execution.
2Measurement precision
If measurement information is configured to compensate for propagation delay differences, then measurement capability is improved, but user experience deteriorates
Solution Approach 1:
The terminal device autonomously calculates propagation delays and generates delay difference information without requiring network intervention or configuration. This self-service approach reduces network overhead and improves measurement capability while maintaining smooth user experience, as the terminal actively manages its own measurement needs without affecting user-perceived performance.
3Reliability
If propagation delay differences are compensated through measurement configuration, then communication reliability is improved, but communication time increases
Solution Approach 1:
The terminal device reports calculated delay difference information back to the network device, which uses this feedback to adjust measurement configurations. This feedback mechanism enables the system to adapt measurement parameters based on actual propagation conditions, improving communication reliability while minimizing the time overhead associated with delay compensation through continuous optimization.
