Anchor Process Indication for Wireless Acknowledgement Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems, particularly those using millimeter waves, face challenges in efficiently handling acknowledgement processes due to the need for precise timing and physical properties, leading to increased signaling overhead, especially with the ubiquitous use of beamforming.
Innovation Solution
The implementation of a method that uses an anchor process indication and relative process indication to transmit acknowledgement signaling, allowing for a dynamic codebook that omits unnecessary processes, thereby reducing signaling overhead by using a relative indication that requires fewer bits than a full ID, particularly suitable for 5G and future wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full process IDs are used to indicate acknowledgement processes, then process identification is complete and unambiguous, but signaling overhead increases
Solution Approach 1:
The patent segments the process indication into two parts: a group ID that identifies a group of acknowledgement processes, and a relative process indication that identifies the specific process within that group. This segmentation allows the system to use smaller indication fields while maintaining complete process identification capability, thereby reducing signaling overhead without sacrificing identification accuracy.
Solution Approach 2:
The patent introduces a hierarchical dimension to process indication by organizing acknowledgement processes into groups. Instead of using a single flat identifier, the system uses a two-dimensional approach: group ID (first dimension) and relative process indication (second dimension). This dimensional change enables more efficient encoding and reduces the total number of bits required for process identification.
2Productivity
If a dynamic codebook is used to omit unnecessary processes, then signaling efficiency improves, but codebook management complexity increases
Solution Approach 1:
The patent implements a dynamic codebook where the set of acknowledgement processes is not fixed but can be adjusted based on actual communication needs. The codebook is dynamically configured through group IDs and relative process indications, allowing the system to include or exclude specific processes from acknowledgement signaling as required, thereby improving signaling efficiency while adapting to varying system conditions.
3Quantity of substance
If relative process indication is used instead of full ID, then number of bits required is reduced, but interpretation complexity increases
Solution Approach 1:
The patent performs preliminary organization of acknowledgement processes into groups with assigned group IDs before the actual indication takes place. This preliminary action creates a structured framework where relative process indications can be efficiently interpreted. The receiving device is pre-configured with the group structure, so when a relative indication is received, the interpretation is straightforward: combine the known group ID with the relative indication to identify the target process, minimizing interpretation complexity.
