Physical Shared Channel Patterns for Repetition Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Repetition transmission in radio communication systems, such as those used in LTE and NR, requires multiple resource occupations, leading to high performance overheads and inefficiencies, particularly in scenarios demanding high reliability like URLLC and mMTC.
Innovation Solution
The implementation of a data transmission method that utilizes pre-configured physical shared channel patterns for repetition transmission, allowing for efficient data transmission and demodulation, reducing resource occupation by using K physical shared channel patterns for data transmission and demodulation, where K is an integer greater than 1.

Engineering Contradiction Analysis
1Reliability
If repetition transmission occupies multiple resources multiple times, then transmission reliability is improved, but resource occupation and performance overhead increase
Solution Approach 1:
The patent pre-configures multiple physical shared channel patterns (first pattern, second pattern, etc.) before transmission. The sender and receiver agree on these patterns in advance, allowing the sender to select appropriate patterns for repetition transmission without real-time negotiation, thus reducing signaling overhead and resource occupation while maintaining reliability
Solution Approach 2:
The patent segments the repetition transmission process by assigning different physical shared channel patterns to different repetition instances. Instead of using the same resource pattern repeatedly, the system divides the transmission into multiple segments using distinct patterns (first pattern for initial transmission, second pattern for repetition, etc.), which improves resource utilization efficiency
2Quantity of substance
If multiple physical shared channel patterns are pre-configured, then resource occupation is reduced, but system complexity increases
Solution Approach 1:
The patent creates simplified copies of channel patterns by defining them as template structures (first physical shared channel pattern, second physical shared channel pattern) that can be reused. These pattern copies contain essential structural information that can be instantiated multiple times with different parameters, reducing the need to define complete channel configurations from scratch and lowering system complexity
