Dynamic Transmit Power Reallocation for Dual Connectivity Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual connectivity devices face inefficiencies in transmit power allocation, leading to high packet drop and retransmission rates when communicating through multiple wireless protocols, as traditional methods do not dynamically reallocate power based on performance thresholds.
Innovation Solution
A system and method that monitor packet drop and retransmission rates to dynamically reallocate transmit power from one wireless communication protocol to another, reducing channel assignment and reallocating power to improve network resource utilization and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit power is statically allocated to multiple wireless communication protocols, then device complexity is reduced, but packet drop and retransmission rates increase
Solution Approach 1:
The patent implements dynamic transmit power reallocation by continuously monitoring packet drop and retransmission rates for each wireless communication protocol and adjusting power allocation in real-time. When a protocol exceeds performance thresholds, power is dynamically shifted from that protocol to others with better performance, resolving the contradiction between static simplicity and dynamic adaptability
Solution Approach 2:
The system establishes a feedback loop where packet drop and retransmission rate metrics are continuously collected, analyzed, and used to adjust transmit power allocation. This closed-loop feedback mechanism enables the system to learn from performance data and automatically optimize power distribution, improving reliability without requiring complex manual configuration
2Reliability
If transmit power is reallocated to protocols with higher error rates, then packet drop rate decreases, but power allocation efficiency decreases
Solution Approach 1:
The patent changes the allocation parameter from fixed power distribution to dynamic power distribution based on protocol performance parameters. By monitoring packet drop and retransmission rates as key parameters, the system adjusts power allocation proportions in real-time, shifting power from underperforming protocols to performing protocols, thereby improving overall transmission efficiency and reducing wasted energy
3Power
If channel assignment is reduced for one protocol, then transmit power for another protocol increases, but network resource utilization may decrease
Solution Approach 1:
The patent applies local quality optimization by treating each wireless communication protocol as a separate channel with its own performance characteristics. Instead of uniform power allocation, the system assigns different power levels to different protocols based on their individual packet drop and retransmission rates, allowing each protocol to receive appropriate power proportional to its actual performance and network conditions

AI summary
Systems and methods are provided for dynamically reallocating available transmit power on a dual connectivity user device. A retransmission rate is monitored for the user device that can simultaneously communicate using two or more wireless communication protocols. It is determined that the retransmission rate for the user device is above a threshold for communications using a first wireless communication protocol, such as LTE. Channel assignment of a second wireless communication protocol, such as 5G, is reduced, thus allowing the user device to reallocate a portion of the transmit power previously allocated for the second wireless communication protocol to the first wireless communication protocol to improve the retransmission rate for the first wireless communication protocol.
