Terminal Device Type Identification via Random Access Preamble Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks where Reduced Capability (RedCap) terminals and common terminals coexist, early identification of terminal types is crucial to avoid unreasonable resource assignment and maintain service quality, as failure to do so can impact the performance of common terminals.
Innovation Solution
A method for identifying terminal device types during the initial random access procedure by acquiring and analyzing random access preamble information and transmission data scheduling messages, allowing for the differentiation between RedCap and common terminals, and configuring specific resources or preambles for RedCap terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RedCap terminals and common terminals share the same random access resources, then resource utilization is improved, but service quality of common terminals deteriorates due to unreasonable resource assignment
Solution Approach 1:
The patent segments the random access resources by introducing terminal capability indication information that distinguishes between RedCap terminals and common terminals. This segmentation allows the system to allocate different resources or apply different scheduling strategies for different terminal types, thereby maintaining service quality for common terminals while enabling efficient resource utilization for RedCap terminals.
2Measurement precision
If terminal type identification is performed during initial random access procedure, then resource allocation accuracy is improved, but procedure complexity increases
Solution Approach 1:
The patent performs terminal type identification during the initial random access procedure, which is a preliminary action before formal data transmission begins. By determining terminal capability indication information early in the random access phase, the system prepares appropriate resource allocation strategies in advance, avoiding the need for complex real-time adjustments during data transmission while maintaining high identification accuracy.
3Reliability
If separate resources are allocated for RedCap terminals, then service quality of RedCap terminals is improved, but overall resource utilization decreases
Solution Approach 1:
The patent implements a universal resource allocation framework where the same random access resources can serve both RedCap terminals and common terminals, but with differentiated handling based on terminal capability indication information. The base station uses this information to apply appropriate scheduling algorithms and resource allocation strategies for each terminal type, achieving both high service quality and efficient resource utilization through multi-functional resource management.
