Solution Overview

Problem

Existing telecommunications networks lack efficient mechanisms for providing bandwidth resources and uplink or downlink channel instructions to user devices, leading to blocked or delayed communications, interference, and limited data throughput.

Innovation Solution

An RRC controller directly provides carrier aggregation configurations, serving cell determinations, MU-MIMO priorities, and handover procedures to a MAC scheduler without relying on additional network components, using RAN usage data to optimize network slicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If existing telecommunications networks use traditional network components for providing bandwidth resources and channel instructions, then network reliability is maintained through established protocols, but communication delays occur and data throughput is limited

Engineering Contradiction:
Improvedata throughputVSAvoidcommunication delays
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent extracts the RRC controller function from the traditional multi-component network architecture and positions it as a dedicated component within the base station. This extraction allows the RRC controller to directly provide carrier aggregation configurations, serving cell determinations, MU-MIMO priorities, and handover procedures to the MAC scheduler without relying on additional network components, thereby reducing communication delays and improving data throughput.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The RRC controller performs preliminary actions by pre-determining carrier aggregation configurations, serving cell assignments, MU-MIMO priorities, and handover procedures based on RAN usage data. These preliminary configurations are then provided to the MAC scheduler for immediate execution, eliminating the need for real-time computation and reducing communication delays.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If additional network components are used to provide carrier aggregation configurations and scheduling instructions, then configuration accuracy is improved, but device complexity and processing overhead increase

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidnetwork component complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the RRC controller with the base station architecture, combining the functions of carrier aggregation configuration, serving cell determination, MU-MIMO priority assignment, and handover procedure generation into a single integrated component. This merging maintains configuration accuracy while reducing the number of separate network components and simplifying the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The RRC controller is designed as a multi-functional component that performs multiple tasks: receiving RAN usage data, determining carrier aggregation configurations, identifying serving cells, assigning MU-MIMO priorities, and generating handover procedures. This universality allows a single component to provide comprehensive network slicing support without requiring multiple specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If traditional scheduling mechanisms are used without direct RRC controller intervention, then network stability is maintained, but spectrum efficiency is limited

Engineering Contradiction:
Improvespectrum efficiencyVSAvoidnetwork stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The RRC controller receives RAN usage data that provides feedback on network conditions, including channel quality indicators, quality of service class identifiers, packet loss rates, resource usage metrics, and scheduling delays. Based on this feedback, the controller dynamically adjusts carrier aggregation configurations, serving cell assignments, and MU-MIMO priorities to optimize spectrum efficiency while maintaining network stability through controlled changes.

Inventive Principle:
Principle #23Feedback

AI summary

The technology disclosed herein relates to a radio resource control (RRC) controller of an RRC component in a central unit of a telecommunications network (e.g., 4G, 5G, 6G, another generation communication system, or one or more combinations thereof) for providing telecommunication services to user devices via network slicing. The RRC controller can receive radio access network (RAN) usage data (e.g., a time-averaged channel quality indicator) for a serving cell or component carriers corresponding to a base station. In addition, the RRC controller can determine a carrier aggregation configuration for a user device or use case based on the RAN usage data. In embodiments, the RRC controller determines a serving cell for the user device or use case based on the RAN usage data. Further, the RRC controller can provide the carrier aggregation configuration or the determined serving cell to a medium access control (MAC) scheduler.
