Multi-Carrier Wireless Configuration via Minimum Aggregation Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, establishing multiple carriers between User Equipment (UE) and Base Station (BS) is challenging due to varying UE capabilities and the need for efficient frequency allocation, especially in scenarios where wide bandwidths are difficult to allocate.
Innovation Solution
A method is introduced where the BS transmits minimum aggregation information to the UE, allowing configuration of at least one carrier for initial communication, and subsequently provides new aggregation information based on UE capabilities, facilitating hierarchical aggregation and accurate wireless configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the BS transmits detailed aggregation information for all M carriers to the UE, then the UE can achieve complete carrier configuration capability, but the system complexity and signaling overhead increase significantly
Solution Approach 1:
The patent segments carrier aggregation information into two distinct parts: minimum aggregation information (necessary for initial access and basic communication) and additional aggregation information (for enhanced capability). This segmentation allows the system to transmit only essential information initially, reducing signaling overhead while maintaining the ability to provide complete configuration when needed.
Solution Approach 2:
The patent implements preliminary action by transmitting minimum aggregation information before detailed carrier configuration. The UE first receives and processes essential aggregation parameters enabling initial communication, then subsequently receives additional aggregation information for optimized carrier setup. This preliminary approach reduces initial system complexity while preserving full adaptability.
2Productivity
If the BS waits to determine UE capability before transmitting aggregation information, then the information transmission can be optimized, but the carrier establishment time increases
Solution Approach 1:
The patent applies preliminary action by transmitting minimum aggregation information immediately without waiting for UE capability determination. This enables the UE to start processing carrier configuration in parallel with capability reporting, significantly reducing overall establishment time while maintaining optimization potential through subsequent capability-based refinement.
Solution Approach 2:
The patent implements a dynamic information transmission strategy where the BS first sends minimum aggregation information, then adapts subsequent transmissions based on UE capability feedback. This dynamic approach allows the system to maintain fast initial setup while optimizing resource allocation based on actual UE capabilities, achieving both speed and efficiency.
3Quantity of substance
If the system supports a large number of M carriers for aggregation, then the bandwidth utilization improves, but the difficulty of frequency allocation and UE capability matching increases
Solution Approach 1:
The patent segments the large set of M carriers into minimum aggregation carriers (essential subset) and additional aggregation carriers (optional extensions). This segmentation simplifies frequency allocation by first establishing a manageable core set of carriers, then selectively adding more carriers based on UE capability and network conditions, reducing overall allocation complexity while maintaining high bandwidth utilization.
Solution Approach 2:
The patent applies local quality by providing different levels of aggregation information to different UEs based on their specific capabilities. The BS transmits minimum aggregation information to all UEs uniformly, then provides additional carrier-specific information only to UEs that support those carriers. This localized approach enables support for many carriers in the system while keeping individual UE configuration manageable.

AI summary
A method of performing wireless communication in a multi-carrier system by a User Equipment (UE) comprises receiving minimum aggregation information on at least one carrier which is determined as a default irrespective of carriers supportable by the UE, configuring the at least one carrier on a basis of the minimum aggregation information, and performing communication using the at least one carrier.
