Base Station Measurement Object Configuration for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTE-advanced system is limited by a maximum number of measurement object identities (MeasObjectIds), preventing the base station from configuring additional carriers for carrier aggregation, which restricts the maximum data rate and hinders handovers between different radio access technologies.
Innovation Solution
A method and device that allow the configuration of additional measurement objects and reporting configurations beyond the standard 32, enabling the base station to receive measurement results from communication devices, thereby supporting more carriers and improving data rates and mobility management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station configures only 32 measurement objects according to the standard limit, then the system maintains compatibility with existing standards and devices, but the maximum data rate of carrier aggregation is not reached and additional carriers cannot be configured
Solution Approach 1:
The patent segments the measurement object configuration into two distinct types: first type configurations (up to 32 MeasObjects) and second type configurations (additional MeasObjects beyond 32). This segmentation allows the system to maintain compatibility with existing 32-object limits while introducing a separate mechanism for additional objects, thereby enabling higher data rates without overwhelming the system with a single complex configuration structure.
Solution Approach 2:
The patent introduces a new dimension to the measurement object configuration by adding a type identifier (first type or second type) to the existing measurement object structure. This dimensional change allows the system to differentiate between standard and extended measurement objects, enabling the configuration of more than 32 measurement objects while maintaining backward compatibility with existing systems that only recognize the first type.
2Adaptability or versatility
If the base station cannot configure more carriers due to the 32 measurement object limit, then the system remains simple and standards-compliant, but carrier aggregation performance is restricted and handovers between different radio access technologies are hindered
Solution Approach 1:
The patent segments measurement object configurations into first type (standard, up to 32 objects) and second type (extended, additional objects). This segmentation enables the base station to configure more carriers for carrier aggregation and handovers by utilizing second type configurations, while keeping the first type configurations for basic operations, thus improving adaptability without creating a single monolithic complex system.
Solution Approach 2:
The patent creates a universal measurement object configuration framework that can handle both standard (first type) and extended (second type) measurement objects through a unified interface. The base station can selectively apply first type configurations for compatibility and second type configurations for enhanced carrier aggregation and handover capabilities, making the system multi-functional and adaptable to different operational requirements.
Data Source
AI summary
A base station for handling communication operations with a communication device comprising a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise transmitting at least one configuration of a first type for configuring 32 measurement objects (MeasObjects) to the communication device; transmitting at least one configuration of a second type for configuring at least one MeasObject in addition to the 32 MeasObjects to the communication device, wherein the second type is different from the first type; receiving a measurement result corresponding to one of the 32 MeasObjects from the communication device; and receiving a measurement result corresponding to one of the at least one MeasObject from the communication device.
