Base Station Carrier Aggregation for Simultaneous Voice Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack dynamic control over carrier aggregation service in base stations, failing to efficiently manage simultaneous voice and data communications, which can lead to suboptimal resource allocation and communication quality.
Innovation Solution
A method and system that dynamically invoke carrier aggregation service for a user equipment (UE) when simultaneous voice and data communication is detected, and transition to single-carrier service when such communication ends, based on monitoring the type of communication engaged by the UE, allowing the base station to adjust the air interface connection accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carrier aggregation service is continuously provided to support simultaneous voice and data communication, then communication quality and service capability are improved, but device complexity and resource allocation overhead increase
Solution Approach 1:
The base station dynamically adjusts carrier aggregation configuration based on real-time detection of simultaneous voice and data communication. When both communication types are detected, the base station configures multiple carriers with appropriate resource allocation; when only one type is detected, it uses single-carrier mode. This dynamic adaptation resolves the contradiction by providing high reliability only when needed while reducing complexity during single-communication-mode operation.
Solution Approach 2:
The system changes the carrier aggregation parameter (number of carriers) based on communication type detection. The base station monitors communication patterns and adjusts the carrier configuration parameter accordingly - switching between single-carrier and multi-carrier modes. This parameter change enables the system to maintain high communication quality when required while avoiding unnecessary complexity during single-mode communication.
2Adaptability or versatility
If carrier aggregation service is provided for all UEs, then service capability is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The base station applies carrier aggregation service selectively to specific UEs based on their communication patterns rather than uniformly to all UEs. By detecting which UEs engage in simultaneous voice and data communication, the system provides enhanced service capability (carrier aggregation) locally to those specific users who need it, while other users continue with simpler single-carrier service. This local differentiation improves resource allocation efficiency by avoiding unnecessary carrier aggregation overhead for users who don't require it.
Solution Approach 2:
Instead of providing full carrier aggregation service to all UEs, the system applies partial action - using single-carrier mode for UEs with single-type communication and full carrier aggregation only for UEs with simultaneous voice and data communication. This partial application of the service resolves the contradiction by providing adaptability where needed while maintaining productivity through simplified service elsewhere.
3Device complexity
If single-carrier service is used to reduce complexity, then device complexity is reduced, but communication efficiency deteriorates when simultaneous voice and data communication occurs
Solution Approach 1:
The base station dynamically switches between single-carrier and carrier aggregation modes based on real-time detection of communication patterns. When simultaneous voice and data communication is detected, the system transitions to multi-carrier mode to maintain communication efficiency; when only single-type communication is detected, it uses single-carrier mode to reduce complexity. This dynamic switching resolves the contradiction by adapting the system complexity to the actual communication requirements.
Solution Approach 2:
The system implements feedback through continuous monitoring of UE communication patterns. The base station detects whether UEs are engaged in voice communication, data communication, or both simultaneously, and uses this feedback information to adjust carrier aggregation configuration. This feedback mechanism ensures that communication efficiency is maintained when needed (through carrier aggregation) while complexity is reduced when possible (through single-carrier mode), resolving the contradiction between these two parameters.

AI summary
A method and system for dynamically controlling when a base station will provide a UE with carrier aggregation service rather than serving the UE on just a single carrier. The base station dynamically invokes carrier aggregation service for the UE in response to detecting simultaneous voice and data communication by the UE. And the base station dynamically discontinues providing carrier aggregation service for the UE, and transitions to serving the UE on just a single carrier, in response to detecting that the UE's simultaneous voice and data communication has ended and that the UE is engaged in just voice communication or just data communication.
