Multi-Carrier Power Amplifier Allocation for MIMO Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In MIMO radio networks, power amplifiers waste resources due to the use of minimum sharable power values, leading to inefficiencies in power utilization across different radio standards.
Innovation Solution
A method and device that adjust carriers with maximum transmit power onto power amplifiers with maximum available power, iteratively updating until all carriers are adjusted, determining a minimum available power as the sharable power, and optimizing power sharing among cells with neighbor or interference relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the minimum value of sharable power among multiple power amplifiers is used, then power sharing is enabled, but power resource waste occurs because higher available power remains unused
Solution Approach 1:
The patent introduces dynamic carrier adjustment where carriers are iteratively reassigned to power amplifiers based on real-time available power calculations. The system dynamically determines which carrier should be adjusted to which power amplifier by comparing transmit power requirements with available power capacity, enabling flexible adaptation that maximizes utilized power while maintaining power sharing capability across multiple radio standards
Solution Approach 2:
The patent changes the parameter used for power sharing determination from a static minimum value approach to a dynamic summation approach. Instead of using the minimum available power across all power amplifiers, the system calculates the sum of available powers from multiple power amplifiers and uses this total to determine the sharable power, thereby changing the fundamental parameter of power sharing calculation to eliminate waste
2Loss of energy
If carriers are adjusted to maximize power utilization, then power resource waste is reduced, but system complexity increases due to iterative adjustment processes
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously calculates available power for each power amplifier, compares it with carrier transmit power requirements, and adjusts carrier assignments accordingly. This feedback loop iteratively refines the carrier-to-power amplifier mapping to maximize power utilization while keeping the adjustment process manageable through systematic comparison and decision rules
