Uplink Control Information Reporting Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently selecting an uplink control information reporting mode, particularly in carrier-aggregated scenarios, leading to latency and reliability issues due to differences in coverage and channel conditions across multiple serving cells.
Innovation Solution
A communication device dynamically selects an uplink control information reporting mode based on signaling and measurements, allowing for separate transmission of uplink control information over multiple serving cells, optimizing latency and reliability by switching between modes as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink control information is transmitted separately over multiple serving cells, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic switching between two reporting modes: a first mode where uplink control information is transmitted separately over multiple serving cells, and a second mode where it is transmitted over a single serving cell. The communication device dynamically selects which mode to use based on real-time channel conditions and coverage requirements, allowing the system to adapt between reliability optimization and complexity reduction as needed
2Reliability
If uplink control information is transmitted over multiple serving cells, then reliability is improved, but transmission time increases
Solution Approach 1:
The system dynamically switches between reporting modes based on real-time channel conditions. When channel conditions are good and latency is critical, the system uses the second mode (single serving cell transmission) to reduce latency. When reliability is more critical and channel conditions permit, the system uses the first mode (multiple serving cells transmission) to improve reliability, thus dynamically balancing the time-reliability tradeoff
3Productivity
If adaptive reporting modes are implemented, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent changes the reporting mode parameter dynamically based on channel conditions and coverage requirements. The system monitors channel quality metrics and adjusts the uplink control information transmission mode accordingly, switching between separate transmission over multiple cells and combined transmission over a single cell. This parameter-based adaptation allows the system to optimize communication efficiency for different operational scenarios without requiring complete system redesign

AI summary
Techniques for wireless communications are described. A mode for reporting uplink control information may be selected when a first serving cell and a second serving cell are both configured with uplink control resources. The reporting modes may include a mode for transmitting uplink control information over one uplink control resource or over multiple uplink control resources. Multiple sets of uplink control information may be separately generated for different sets of component carriers or different transmission/reception points. After selecting the reporting mode, the multiple sets of uplink control information may be transmitted over one or multiple uplink control resources in accordance with the selected reporting mode. Communication devices may switch between the reporting modes based on obtained information or calculations.
