Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently transmitting different types of services, such as eMBB, URLLC, and mMTC, within the same time interval, due to interference and resource allocation issues.
Innovation Solution
A method and apparatus that configure and transmit rate matching patterns for different services, allowing for simultaneous data transmission by mapping resources in a way that avoids interference with important information resources, such as reference signals and synchronization signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple services (eMBB, URLLC, mMTC) are transmitted simultaneously in the same time interval, then service diversity and system capability are improved, but interference between services and resource allocation complexity increase
Solution Approach 1:
The patent segments the time-frequency resource grid into multiple rate matching patterns, where each pattern is dedicated to specific services (e.g., eMBB, URLLC, mMTC). This segmentation allows different services to be mapped to distinct resource regions within the same time interval, enabling service diversity while preventing interference through spatial and spectral separation.
2Productivity
If rate matching patterns are configured for different services, then resource utilization efficiency is improved, but control signaling overhead and system complexity increase
Solution Approach 1:
The patent configures rate matching patterns in advance through higher-layer signaling (RRC configuration) before actual data transmission. This preliminary configuration establishes the resource mapping rules for different services, allowing the system to efficiently utilize resources during data transmission without requiring complex real-time control signaling for each transmission instance.
3Reliability
If important information resources (reference signals, synchronization signals) are protected from interference, then transmission reliability is improved, but available resources for data transmission are reduced
Solution Approach 1:
The patent extracts and isolates important information resources (reference signals, synchronization signals, broadcast channels) from the general data transmission resources by defining specific rate matching patterns that exclude these critical resources. This extraction ensures that data transmission for different services does not interfere with essential signaling, maintaining transmission reliability while still utilizing the maximum available resources for data.
