Terminal Device Handover Uplink Control Information Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional handover processes, terminal devices maintain connections with both source and target network devices, leading to increased power consumption due to the continuous exchange of information with the source network device.
Innovation Solution
The terminal device is configured to receive an HO command for handover and refrain from sending Uplink (UL) control information to the source network device, thereby reducing power consumption by minimizing information exchange during handover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device maintains connections with both source and target network devices during handover, then the handover reliability is improved, but the power consumption increases
Solution Approach 1:
The patent extracts and removes the transmission of uplink control information to the source network device during handover, while maintaining the connection. This selective removal reduces power consumption by eliminating unnecessary communication activities with the source network device, while the connection itself is preserved for potential fallback or coordination purposes.
2Stability of the object's composition
If the terminal device retains configuration from source network device during handover, then the connection stability is improved, but the information processing complexity increases
Solution Approach 1:
The patent applies partial action by selectively retaining only the necessary uplink control information configuration from the source network device, while discarding other unnecessary configurations. This partial retention maintains connection stability for essential control functions while reducing the overall complexity of information processing by eliminating redundant configuration management.

AI summary
Provided are an information processing method, a terminal device, a chip, a computer-readable storage medium, a computer program product and a computer program. The method includes that: a terminal device receives a handover command which is used for configuring the terminal device to perform handover during which connections with a source network device and a target network device are both maintained; and the terminal device does not send uplink control information to the source network device.
