Dynamic Antenna Element Allocation for Beam-Formed Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In beam-formed communication, existing technologies face challenges in efficiently managing the number of antenna elements to optimize power distribution across multiple channels, leading to inefficiencies in transmission and reception, particularly in scenarios with asymmetric attenuation.
Innovation Solution
The proposed solution involves an apparatus and method that dynamically adjust the number of antenna elements by redistributing them between groups to maintain or optimize the number of antenna elements used for beam-formed communication, based on measured power loss, to balance reception power across multiple channels and maintain channel conditioning.

Engineering Contradiction Analysis
1Reliability
If the number of antenna elements is increased for beam-formed communication, then the reception power and channel conditioning are improved, but the device complexity and power distribution balance deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of antenna element allocation across multiple channels based on real-time power loss measurements. The system continuously monitors channel conditions and redistributes antenna elements to maintain optimal reception power balance, transforming the static antenna configuration into a dynamic adaptive system that responds to changing channel conditions
Solution Approach 2:
The system changes the parameter of antenna element allocation by adjusting the number of antenna elements assigned to each channel based on measured power loss. This parameter adjustment allows the system to optimize channel conditioning by allocating more antenna elements to channels with higher power loss, thereby balancing the reception power across channels
2Reliability
If antenna elements are redistributed to balance power across channels, then the communication power balance is improved, but the system adaptability requirements increase
Solution Approach 1:
The patent employs feedback mechanisms where the system measures power loss in each channel and uses this information to determine optimal antenna element allocation. The measured power loss serves as feedback that drives the redistribution decision, creating a closed-loop control system that continuously optimizes power balance across channels based on actual channel conditions
Solution Approach 2:
The system dynamically adapts its antenna element configuration in response to measured power loss conditions. By continuously monitoring channel power characteristics and adjusting antenna allocation accordingly, the system achieves adaptive power balancing that responds to changing channel conditions without requiring manual reconfiguration
