Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing data splits between New Radio (NR) channels and legacy channels, particularly in scenarios where concurrent operation leads to decreased quality and reliability due to conflicting antenna ports.

Innovation Solution

A method and apparatus for dynamically adjusting the data split between NR and legacy channels based on the ratio of data flow and channel quality, allowing for improved communication quality and reliability by modifying the data distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted over both NR channels and legacy channels concurrently, then data throughput is increased, but communication quality and reliability decrease due to conflicting antenna ports

Engineering Contradiction:
Improvedata throughputVSAvoidcommunication quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of the data split ratio between NR and legacy channels based on real-time channel conditions, data flow ratios, and antenna port conflicts. The base station and UE continuously monitor these parameters and modify the data distribution dynamically, transitioning from a static to a dynamic resource allocation scheme that adapts to changing network conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of data split ratio between NR and legacy channels based on monitored conditions including channel quality, data flow ratios, and antenna port conflict levels. By adjusting this key parameter in response to changing conditions, the system optimizes the balance between throughput and communication quality.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If antenna ports are used for both NR and legacy channels simultaneously, then resource utilization is improved, but interference increases and reliability decreases

Engineering Contradiction:
Improveresource utilizationVSAvoidinterference
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the base station and UE monitor antenna port conflict conditions, channel quality, and data flow ratios. Based on this feedback, the system adjusts the data split ratio to reduce interference from antenna port conflicts while maintaining effective resource utilization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies different data distribution strategies to different channels (NR vs. legacy) based on their specific conditions. Rather than uniform resource allocation, the system tailors the data split ratio locally to each channel's characteristics, including channel quality and antenna port availability, thereby reducing interference while maintaining overall resource efficiency.

Inventive Principle:
Principle #3Local quality

3Device complexity

If data split ratio is fixed, then system complexity is reduced, but ability to adapt to changing channel conditions is limited

Engineering Contradiction:
Improvesystem complexityVSAvoidadaptability to channel conditions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a fixed data split ratio to a dynamic adjustment mechanism that adapts to changing channel conditions. The system monitors channel quality, data flow ratios, and antenna port conflicts in real-time and modifies the data distribution accordingly, enabling adaptability without requiring overly complex centralized control.

Inventive Principle:
Principle #15Dynamics

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from abase station, an indicator of a data split between a New Radio (NR) channel and a legacy channel. Accordingly, the UE may transmit, to the base station, an indicator of a modification of the data split based at least in part on a ratio of an amount of data flowing over the NR channel to a total amount of data flowing over the NR channel and the legacy channel. Additionally, or alternatively, the UE may transmit, to the base station, an indicator of a modification of the data split based at least in part on an indicator of a quality of the legacy channel. Numerous other aspects are provided.
