Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio telecommunication technologies face challenges in achieving flexible control signaling without incurring undesirably large signaling overhead, particularly in the context of transmission of measurement information with adaptive size, leading to inefficient resource usage and increased blind detection processes.
Innovation Solution
A method and feedback radio node configured with multiple sets of transmission resources for control information, where different sets are associated with different size classes and formats, allowing control information to be transmitted based on a reference size, ensuring both transmitter and receiver can determine the appropriate resource and format for transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measurement information with adaptive size is transmitted, then flexibility in data transmission is improved, but signaling overhead increases
Solution Approach 1:
The patent applies parameter changes by using a reference size parameter to determine the resource set for transmitting measurement information. Instead of using the actual variable size of the measurement information, the system changes the parameter to a reference size that maps to predefined resource sets, thereby maintaining flexibility while avoiding overhead associated with signaling the actual size.
Solution Approach 2:
The patent introduces an intermediary mechanism where the reference size acts as a mediator between the actual measurement information size and the resource allocation. The reference size is not the actual size but an intermediate value that determines which resource set to use, eliminating the need to signal the actual size while still enabling flexible transmission.
2Reliability
If multiple blind detection processes are used to determine transmission resources, then reliability of resource selection is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple resource sets with different sizes before the actual transmission. The reference size is determined in advance based on the measurement information, and the corresponding resource set is selected from the pre-defined sets, eliminating the need for multiple blind detection processes during transmission and reducing processing time while maintaining reliability.
3Loss of information
If control information size is increased to accommodate all measurement information, then completeness of data transmission is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the resource set selection dynamic based on the reference size. Different resource sets with different sizes are dynamically selected according to the reference size of the measurement information, allowing the system to adapt to different data completeness requirements while optimizing resource efficiency for each specific transmission scenario.
