Wireless Signaling Overhead Reduction via Time Window Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in NR Release 16, there is a need to enhance the reliability and reduce latency of UCI transmission over the PUCCH to support more efficient communication, as existing methods are inefficient in managing time duration and multicarrier symbol types within a time window.
Innovation Solution
A method and device that utilize a physical layer signaling with a first field indicating the time duration of a time window and a second field determining the type of multicarrier symbols, allowing for simultaneous indication of time duration and symbol type, thereby reducing signaling overhead and simplifying operations at the receiving end, while maintaining flexibility in uplink and downlink configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate signaling is used to indicate time duration and multicarrier symbol types, then flexibility in configuration is improved, but signaling overhead increases
Solution Approach 1:
The patent combines the indication of time duration and multicarrier symbol types into a single signaling message. The first field indicates the time duration of the time window, while the second field indicates the types of multicarrier symbols within that window. This merging approach reduces signaling overhead while maintaining the ability to flexibly configure both time duration and symbol types simultaneously.
2Manufacturing precision
If separate signaling is used for time duration and symbol type indication, then configuration precision is improved, but receiving operation complexity increases
Solution Approach 1:
By merging the indication fields into a single signaling message with a clear structure (first field for time duration, second field for symbol types), the patent reduces the number of separate signaling operations the receiving end must process. This maintains configuration precision while simplifying the receiving operation.
3Reliability
If detailed indication of each time unit's symbol types is provided, then transmission reliability is improved, but blind detection complexity increases
Solution Approach 1:
The patent segments the time window into K first-type time units and uses the second field to indicate the types of multicarrier symbols for these time units. This segmentation approach provides detailed information about symbol types in each time unit, improving transmission reliability while organizing the information in a structured manner that reduces blind detection complexity compared to providing individual indications for each time unit.
