Wireless Device Blind Detection for Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face significant signaling overhead due to the need to transmit scheduling assignments and AMC parameters, which consumes channel resources that could be used for payload transmission.
Innovation Solution
Implementing a method where wireless devices perform blind detection on transmission data signals to determine scheduling assignments and AMC parameters, eliminating the need for explicit signaling of these parameters by using uniquely associated codings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit signaling of scheduling assignments and AMC parameters is used, then wireless devices can reliably identify intended data and decode transmission, but signaling overhead increases consuming channel resources
Solution Approach 1:
The patent extracts the scheduling assignment information and AMC parameters from explicit signaling and embeds them directly into the transmission data structure. By taking out the need for separate control signaling and integrating the essential identification information into the data payload itself, the system reduces signaling overhead while maintaining the ability for wireless devices to identify intended data through blind detection of embedded identifiers
Solution Approach 2:
The transmission data structure is designed to be self-identifying through embedded device identifiers or pattern recognition elements. Instead of requiring external signaling to tell devices what data is intended for them, the data structure itself contains the necessary identification information that enables receiving devices to autonomously determine whether the transmission is intended for them through blind detection
2Loss of information
If control signaling is transmitted to convey scheduling assignments and AMC parameters, then transmission parameters are accurately communicated, but channel resources are consumed that could be used for payload transmission
Solution Approach 1:
The patent merges the control information (scheduling assignments and AMC parameters) with the payload data into a single integrated transmission structure. By combining what were previously separate control signaling and data transmission into one unified format, the system eliminates the need for dedicated control channel resources while preserving all necessary parameter information for accurate decoding
Solution Approach 2:
The transmission data structure is designed to serve multiple functions simultaneously: it carries the payload data, embeds scheduling assignment information, includes AMC parameters, and provides device identification capabilities. This multi-functional design eliminates the need for separate specialized signaling channels for each type of information
