Combined UE Carrier Aggregation via Terminal Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals are limited to supporting only one or two downlink component carriers due to legacy constraints and power consumption issues, lagging behind the carrier aggregation capabilities of network base stations, which restricts the achievement of higher data rates despite available network support for up to five component carriers.
Innovation Solution
A combined user equipment (UE) system is introduced, where multiple mobile terminals are coordinated to operate as a single device, leveraging multiple component carriers for enhanced carrier aggregation, allowing five or more carriers to be aggregated and improving spectral efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobile terminals are coordinated to operate as a combined UE system, then the number of aggregated component carriers can exceed five and spectral efficiency is improved, but the device complexity and coordination overhead increase significantly
Solution Approach 1:
Multiple mobile terminals are merged into a single combined UE system that operates as one logical device. The mobile terminals share radio resource control connections and coordinate their component carrier operations through a lead mobile terminal, enabling the system to aggregate more than five component carriers and achieve higher data rates while presenting a unified interface to the network.
2Productivity
If a single UE supports more component carriers, then higher data rates are achieved, but power consumption increases beyond acceptable limits
Solution Approach 1:
The combined UE system segments the component carrier reception tasks across multiple mobile terminals. Each mobile terminal handles only the component carriers it is configured to receive, rather than a single UE attempting to process all carriers. This segmentation distributes the power consumption burden and allows the system to support more component carriers than a single UE could handle alone.
3Adaptability or versatility
If legacy UE constraints limit support to one or two downlink component carriers, then power consumption is controlled, but the network's carrier aggregation capability of up to five carriers cannot be fully utilized
Solution Approach 1:
The combined UE system provides multi-functionality by enabling multiple mobile terminals to collectively support more than five downlink component carriers. This universal approach allows the system to adapt to various network configurations and fully utilize the base station's carrier aggregation capability, overcoming the one-or-two carrier limitation of legacy UEs and achieving higher data rates.

AI summary
A method (700) includes receiving a connection request (204) from a network base station (102) on a primary component carrier (CC) (220P) associated with a primary user equipment (UE) (104P), and connecting to the network base station on the primary CC. The method also includes receiving a configuration message (206) from the network base station. The configuration message instructs operation of at least one secondary CC (220S). The at least one secondary CC is associated with at least one secondary UE (104S). The method also includes, in response to receiving the configuration message, instructing the at least one secondary UE to operate on the at least one secondary CC and receive data (208) from the network base station on the at least one secondary CC.
