Solution Overview

Problem

Current wireless telecommunications systems face inefficiencies in repeat transmission protocols, particularly in LTE networks, due to lack of frequency, time, and redundancy version (RV) diversity, which can impact communication reliability under poor channel conditions and periodic interference.

Innovation Solution

Implementing a method where redundancy versions for data transmission are transmitted in different sequence orders across varying time periods, ensuring each RV is spread across multiple frequency bands and not repeated periodically, thereby enhancing frequency and temporal diversity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If redundancy versions are transmitted periodically in the same sequence order, then transmission protocol simplicity is maintained, but communication reliability deteriorates under periodic interference and poor channel conditions

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidtransmission protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the transmission sequence order variable rather than fixed. The sequence in which redundancy versions (RVs) are transmitted changes based on time period or transmission attempt number, allowing the system to adapt to varying channel conditions and avoid periodic interference patterns, thereby improving communication reliability without requiring complex adaptive algorithms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes periodic action by implementing different sequence orders in different time periods or transmission attempts. This periodic variation in transmission patterns helps distribute redundancy versions across different channel conditions and avoids consistent vulnerability to periodic interference, enhancing reliability while maintaining protocol simplicity through predetermined sequence patterns

Inventive Principle:
Principle #19Periodic action

2Reliability

If the same redundancy version sequence is used across all transmissions, then implementation simplicity is maintained, but frequency diversity is reduced impacting transmission performance

Engineering Contradiction:
Improvetransmission performance consistencyVSAvoidsequence management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements dynamics by varying the redundancy version sequence order across different time periods or transmission attempts. This dynamic approach ensures that the same data block is transmitted with different RV sequences under different channel conditions, improving frequency diversity and transmission performance consistency while keeping the variation pattern simple and predetermined

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying the sequence order parameter of redundancy version transmissions. Different sequence orders are applied in different time periods or transmission attempts, changing the temporal and frequency distribution characteristics of RVs without altering the underlying data or requiring complex real-time adaptation, thus improving performance consistency with minimal complexity increase

Inventive Principle:
Principle #35Parameter changes
