Solution Overview

Problem

Current wireless communication systems face challenges in achieving transmission robustness while minimizing resource usage and system complexity, as adopting multipath configurations for all radio bearers leads to resource wastage and increased complexity.

Innovation Solution

A method that flexibly configures lower-layer transmission paths for radio bearers, allowing for dynamic reconfiguration and rapid switching between RLC bearers to maintain transmission robustness without occupying excessive logical channel space, thereby reducing resource usage and system complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multipath configuration is adopted for all radio bearers, then transmission robustness is improved, but logical channel space is occupied excessively and resources are wasted

Engineering Contradiction:
Improvetransmission robustnessVSAvoidlogical channel space
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by configuring multipath transmission selectively for specific radio bearers based on their service requirements and channel conditions, rather than uniformly for all bearers. This allows transmission robustness to be enhanced where needed while avoiding unnecessary occupation of logical channel space for bearers that do not require multipath configuration.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamic configuration of multipath transmission parameters, allowing the system to adaptively adjust the number of transmission paths, path selection, and resource allocation based on real-time channel conditions and service demands. This dynamic approach ensures transmission robustness is maintained when needed while optimizing resource usage when conditions permit.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multipath configuration is adopted for all radio bearers, then transmission robustness is improved, but system complexity is increased

Engineering Contradiction:
Improvetransmission robustnessVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent reduces system complexity by applying multipath configuration locally to specific radio bearers rather than system-wide. This selective approach minimizes the complexity burden on protocol stacks, processing units, and control mechanisms while still achieving transmission robustness for bearers that require it.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs partial action by implementing multipath transmission for only the necessary portion of radio bearers rather than all bearers. This partial deployment strategy achieves the required transmission robustness for critical services while avoiding the excessive complexity that would result from universal multipath configuration.

Inventive Principle:
Principle #16Partial or excessive action

3Quantity of substance

If flexible configuration of lower-layer transmission paths is implemented, then resource usage is reduced, but transmission robustness may be compromised

Engineering Contradiction:
Improveresource usageVSAvoidtransmission robustness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent resolves this contradiction through dynamic configuration that monitors channel conditions and service requirements in real-time. When channel conditions deteriorate or service demands increase, the system can activate additional transmission paths to maintain robustness. When conditions are favorable, the system reduces path usage to optimize resource efficiency, thus achieving both goals adaptively.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms that continuously monitor transmission performance, channel quality, and resource usage. Based on this feedback, the system dynamically adjusts the configuration of lower-layer transmission paths, ensuring that robustness is maintained when needed while optimizing resource usage during normal operations. The feedback loop enables the system to respond to changing conditions and maintain the appropriate balance between robustness and resource efficiency.

Inventive Principle:
Principle #23Feedback
