Wireless Access Point Carrier Aggregation Beamforming Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for using beamforming with carrier aggregation in wireless communication systems are not efficient or effective, particularly for user equipment (UE) moving within a geographic region or experiencing high interference, as they fail to optimize data transmission rates and connectivity.
Innovation Solution
A wireless access point identifies UE using carrier aggregation and allocates a Primary Component Carrier (PCC) on a frequency band with beamforming capabilities, transitioning to beamforming for improved data transmission by indicating the PCC allocation and exchanging additional communication data using carrier aggregation over that frequency band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming is used for carrier aggregation, then data throughput and connectivity are improved, but current techniques are not efficient or effective for mobile UEs or high interference areas
Solution Approach 1:
The system dynamically switches between beamforming and spatial multiplexing modes based on UE mobility state and channel conditions. The access point monitors UE behavior patterns and automatically adjusts the transmission mode to optimize both throughput and connectivity, resolving the contradiction by making the system adaptive rather than static
Solution Approach 2:
The patent changes the transmission mode parameter based on UE mobility characteristics and interference conditions. By monitoring factors like UE speed, location changes, and signal quality, the system adjusts between beamforming (for high throughput in stable conditions) and spatial multiplexing (for mobility scenarios), thereby optimizing both productivity and reliability
2Reliability
If beamforming is used to provide improved robustness of data transmission, then data transmission reliability is improved, but feedback data requirements increase
Solution Approach 1:
The system applies beamforming selectively only when needed based on channel conditions and UE mobility state, rather than continuously. This partial application reduces the overall feedback data requirements while maintaining high robustness where beamforming is beneficial, resolving the contradiction between reliability improvement and complexity increase
3Reliability
If spatial multiplexing is used to maintain communication for high mobility UEs, then connectivity is maintained, but feedback data requirements are reduced
Solution Approach 1:
The system dynamically adapts the transmission mode based on real-time UE mobility detection and channel conditions. When UE mobility is high or changing rapidly, the system switches to spatial multiplexing which requires less feedback data. This dynamic adaptation maintains connectivity while optimizing feedback requirements based on actual operational conditions

AI summary
A wireless access point to optimize carrier aggregation using beamforming. The wireless access point wirelessly exchanges communication data with User Equipment (UE) over a plurality of frequency bands. The wireless access point identifies a UE using carrier aggregation and identifying a frequency band of the plurality of frequency bands having beamforming capabilities. The wireless access point then allocates the UE using carrier aggregation a Primary Component Carrier (PCC) on the frequency band having beamforming capabilities. In response to the PCC allocation, the wireless access point transfers an indication to the UE indicating the PCC allocation on the frequency band having beamforming capabilities and wirelessly exchanges additional communication data with the UE using carrier aggregation over the frequency band using beamforming.
