Non-IMT Band Usability Detection in Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems operating in carrier aggregation mode, which combine licensed IMT bands and non-IMT bands, face inefficiencies in utilizing non-IMT bands due to unpredictable usability, leading to potential interference and suboptimal bandwidth utilization.
Innovation Solution
The system enhances communication by having user equipment (UE) report carrier type indications and availability patterns to the evolved NodeB (eNB), allowing the eNB to configure measurement thresholds and adjust scheduling configurations, thereby optimizing the use of non-IMT bands and reducing signaling overhead.

Engineering Contradiction Analysis
1Productivity
If the system utilizes non-IMT bands for carrier aggregation to increase bandwidth, then the data transmission capacity is improved, but the interference with primary services and unpredictability of band usability worsen
Solution Approach 1:
The system performs preliminary detection of non-IMT band availability and primary service presence before initiating data transmission. The eNB configures UE to detect and report carrier type indications and availability patterns in advance, allowing the system to pre-determine suitable transmission opportunities and avoid interference with primary services.
Solution Approach 2:
The system implements a feedback mechanism where UE continuously monitors non-IMT bands and reports carrier type indications and availability patterns to the eNB. This feedback loop enables dynamic adjustment of transmission parameters based on real-time band conditions, allowing the system to adapt to changing availability and minimize interference.
2Measurement precision
If the system implements comprehensive monitoring and reporting mechanisms for non-IMT bands, then the usability prediction accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The system extracts only the most essential information for band usability assessment - specifically carrier type indications and availability patterns - and reports these to the eNB. By focusing on key parameters rather than comprehensive band characteristics, the system achieves sufficient prediction accuracy while minimizing signaling overhead.
Solution Approach 2:
The system implements partial monitoring where UE reports carrier type indications and availability patterns selectively based on configured thresholds and event triggers. Rather than continuously reporting all possible parameters, the system uses partial reporting strategies that provide adequate usability prediction while reducing signaling load.

AI summary
The present invention addresses a method, comprising configuring a remote device (UE) for measurements of at least one carrier in a first frequency band which is different from a second frequency band which is licensed used for communication by said remote device, receiving a measurement report from said remote device, and deciding on the usability of the at least one measured carrier in said first frequency band for communication by said remote device. Aiso, a method is proposed, comprising measuring at least one carrier in a first frequency band which is different from a second frequency band which is licensed used for communication by a remote device, and sending, to a network transceiver device, a measurement report of the measurements. Likewise, corresponding computer program products as well as correspondingly configured devices are addressed.
