Coordinated Cell Switching for Relay Terminal Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when a relay terminal and a remote terminal are moving together, cell switching can disrupt relay transmission as existing methods often require separate switches for each terminal, leading to significant impact on relay transmission between them.
Innovation Solution
A method where a terminal device acquires measurement results of links between itself and network devices, determining switching schemes to ensure both terminals remain in the same network cell after switching, allowing for continuous effective relay transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cell switching is performed for relay terminal and remote terminal, then each terminal can independently optimize its connection, but relay transmission between the terminals is significantly disrupted
Solution Approach 1:
The patent merges the cell switching decisions for relay terminal and remote terminal into a coordinated process. The network device determines switching schemes for both terminals simultaneously, ensuring they switch to the same target cell together, thus maintaining relay transmission continuity while achieving optimal connection
2Reliability
If cell switching is performed to optimize signal strength, then individual terminal connections are improved, but relay transmission effectiveness deteriorates due to terminals ending up in different cells
Solution Approach 1:
The patent segments the cell switching process into coordinated phases: measurement phase where both terminals collect signal data, decision phase where network device determines switching schemes, and execution phase where terminals switch together. This segmentation allows simultaneous optimization of signal strength and relay transmission effectiveness
Solution Approach 2:
The patent implements feedback mechanisms where terminals report measurement results to the network device, which then determines appropriate switching schemes. This feedback loop ensures that switching decisions are based on actual signal conditions while maintaining relay transmission integrity

AI summary
The present application discloses a switching method, a terminal device and a network device. The method includes: a first terminal device acquires measurement results of links, where the links include a link between the first terminal device and a first network device and a link between the first network device and a second terminal device; and the first terminal device determines a first switching scheme for the first terminal device and/or a second switching scheme for the second terminal device according to the measurement results. Therefore, after cell switching is performed between a relay terminal and a remote terminal, an effective relay transmission continues between a relay terminal device and a remote terminal device.
