Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently multiplexing uplink control information (UCI) on non-overlapping transmissions, leading to potential power inefficiencies and increased operational complexity.
Innovation Solution
A method and apparatus for a user equipment (UE) to identify UCI for transmission via a first potential uplink control channel transmission and a second non-overlapping uplink transmission, allowing multiplexing based on conditions such as time gaps, priorities, and message sizes, thereby enabling power savings while maintaining network stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If UCI is transmitted on non-overlapping uplink transmissions, then power efficiency is improved, but transmission reliability may deteriorate
Solution Approach 1:
The patent changes the parameter of transmission timing by identifying non-overlapping uplink transmissions and multiplexing UCI from one transmission to another. This allows the UE to consolidate transmissions, enter lower power states more frequently, and improve power efficiency while maintaining reliable UCI delivery through controlled parameter adjustments in the multiplexing process
Solution Approach 2:
The patent introduces a multiplexing mechanism as an intermediary process that transfers UCI from a first potential uplink control channel transmission to a second non-overlapping uplink transmission. This intermediary multiplexing operation enables power savings by eliminating the need for separate transmissions while ensuring UCI reliability through structured conditions and network signaling
2Adaptability or versatility
If UCI multiplexing on non-overlapping transmissions is enabled, then operational complexity increases, but adaptability improves
Solution Approach 1:
The patent implements dynamic adaptability by allowing UCI multiplexing on non-overlapping transmissions based on identified conditions such as time gaps, priorities, and message sizes. The system dynamically adjusts multiplexing decisions based on current transmission conditions, enabling flexible adaptation to different scenarios while managing complexity through condition-based rules
Solution Approach 2:
The patent segments the UCI multiplexing decision process into distinct evaluable conditions including time gap thresholds, transmission priorities, and message size constraints. By dividing the complex multiplexing decision into separate condition checks, the system achieves adaptability while organizing operational complexity into manageable segments

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify uplink control information (UCI) for transmission via a first potential uplink control channel transmission and identify a second uplink transmission that is non-overlapping in time with the first potential uplink control channel transmission. The second uplink transmission may include an uplink shared channel transmission or a second uplink control channel transmission. The UE may transmit the UCI as part of the second uplink transmission based on a determination that the second uplink transmission satisfies one or more conditions.
