Antenna Array Partitioning for Dynamic Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antenna arrays face challenges in managing concurrent connections to different wireless technologies, leading to degraded throughput for user equipment (UE) when multiple access technologies are used simultaneously, as they lack efficient mechanisms to dynamically adjust transmission power and switch UE between technologies to optimize performance.
Innovation Solution
The antenna array is partitioned into distinct portions operating on different access technologies, allowing for independent control and adjustment of transmission power. When throughput degradation occurs, the system reduces the transmission power of antenna elements dedicated to one technology, forcing UE to switch to another technology, thereby improving overall network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna array concurrently supports multiple access technologies (5G and legacy), then the versatility and service coverage are improved, but the throughput for individual technologies degrades due to resource sharing
Solution Approach 1:
The antenna array is partitioned into multiple antenna groups, where each group is dedicated to a specific access technology (5G or legacy). This segmentation allows independent resource allocation and power control for each technology group, eliminating the throughput degradation caused by sharing a single antenna array across multiple technologies.
2Productivity
If transmission power is increased to improve throughput, then the service quality is improved, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts the transmission power of antenna groups based on real-time throughput measurements and UE distribution. When throughput falls below a threshold, the system increases power to the affected antenna group; when throughput is sufficient, it reduces power to conserve energy. This dynamic adaptation resolves the contradiction between maintaining high throughput and minimizing energy consumption.
3Productivity
If the system forces UE to switch between access technologies to balance load, then the throughput for remaining connections is improved, but the device complexity increases
Solution Approach 1:
The system continuously monitors throughput metrics for each access technology and uses this feedback to make automated decisions about power adjustment and UE switching. When throughput for a technology group falls below a threshold, the system automatically increases power to that group or switches affected UEs to the other technology, eliminating the need for complex manual management while maintaining optimal throughput.

AI summary
A method, system, and medium are provided for optimizing an edge-user experience in a first access technology based on dynamic antenna power modifications. In embodiments, when a large volume of UE are located in a particular edge-region of a sector of a cell site, the power supplied to one or more corresponding antenna elements may be reduced or stopped in order to reduce the coverage area of the first access technology and cause a portion of the UE to shift to a second access technology at the cell site. By lowering the volume of UE that are located in a particular edge-region of a sector of a cell site, the remaining portion of the UE that are located in a particular edge-region of a sector of a cell site experience improved throughput.
