Radio Access Control Signaling with Overlapping Transmission Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio telecommunication technologies, particularly in 5G networks, face challenges with signaling overhead due to flexibility requirements, especially in acknowledgement signaling processes, leading to undesirable power output changes and inconsistent behavior.
Innovation Solution
A method and apparatus for configuring user equipment with overlapping transmission resources for different types of control information, allowing transmission to be adjusted based on the partial overlap of these resources to minimize signaling overhead and maintain consistent power output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission resources are configured for different types of control information, then the system flexibility and adaptability are improved, but signaling overhead and resource conflict increase
Solution Approach 1:
The patent merges multiple control information transmissions into a single resource when overlap is detected. The feedback radio node combines first and second type control information in one transmission resource, reducing the total number of resources needed and eliminating the overhead of separate resource configurations while maintaining the ability to convey multiple control types.
Solution Approach 2:
The patent creates a universal transmission resource that can handle multiple types of control information. The feedback radio node is configured to transmit different control information types (first type, second type, or both) depending on availability and overlap conditions, making a single resource multi-functional and reducing the need for dedicated resources for each control type.
2Productivity
If transmission resources partially overlap, then resource utilization efficiency is improved, but transmission behavior consistency deteriorates
Solution Approach 1:
The patent implements dynamic transmission behavior based on real-time resource overlap conditions. The feedback radio node adapts its transmission strategy by determining whether to transmit first type control information, second type control information, or both types together, depending on the overlap status between configured resources. This dynamic adaptation maintains consistency by following defined rules rather than arbitrary decisions.
Solution Approach 2:
The patent uses feedback mechanisms where the feedback radio node determines transmission content based on resource overlap detection. The system monitors the overlap between first and second transmission resources and adjusts transmission behavior accordingly, creating a closed-loop control system that ensures consistent and predictable transmission patterns under varying resource conditions.
3Loss of information
If control information is transmitted on overlapping resources, then signaling overhead is reduced, but power output stability worsens
Solution Approach 1:
The patent ensures continuous and stable power output by maintaining consistent transmission characteristics. When control information is transmitted on overlapping resources, the system follows defined rules for combining control information types, ensuring that power output remains stable and predictable. The feedback radio node avoids abrupt power changes by systematically determining what to transmit based on resource overlap conditions.

AI summary
There is disclosed a method of operating a user equipment in a radio access network, the user equipment being configured with a first transmission resource pertaining to transmission of a first type of control information. The user equipment is further configured with a second transmission resource pertaining to transmission of a second type of control information. The first transmission resource and the second transmission resource partially overlap. The method includes transmitting control information of the first type and/or the second type depending on the partial overlap of the first transmission resource and the second transmission resource.
