Dynamic Uplink Power Allocation for Dual Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication devices (WCDs) face inefficiencies in power transmission due to fixed maximum uplink power settings, leading to diminished user experience and suboptimal throughput, especially when handling dual connectivity with multiple access points across different communication protocols.
Innovation Solution
The system dynamically adjusts the maximum uplink power for each transmitter in WCDs based on historical data analysis, including noise interference, time of day, and location, to proactively set the optimal power level, eliminating the need for incremental power ramping and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If maximum uplink power is hard-set in WCDs, then device simplicity is maintained, but throughput and communication efficiency deteriorate
Solution Approach 1:
The patent implements dynamic power allocation where the maximum uplink power for each transmitter is no longer fixed but can be adjusted in real-time based on network conditions, historical data, and current channel quality, allowing the system to adapt to varying requirements for optimal throughput
Solution Approach 2:
The system changes the power parameter dynamically by analyzing historical data and current channel conditions to determine optimal power levels for each transmitter, replacing the static hard-set approach with a flexible parameter adjustment mechanism
2Use of energy by moving object
If incremental power ramping is used, then power optimization is achieved, but user experience and communication speed deteriorate due to multiple steps
Solution Approach 1:
The system performs preliminary analysis of historical data and channel conditions before actual transmission begins, pre-calculating the optimal power level so that power adjustment happens in advance rather than through incremental ramping during communication
Solution Approach 2:
The patent skips the incremental power ramping process entirely by directly setting the optimal power level based on pre-analysis, rushing through the power adjustment to achieve immediate optimal performance without intermediate steps
3Adaptability or versatility
If dual connectivity is implemented with multiple protocols, then network versatility is improved, but power allocation complexity and load balancing difficulty increase
Solution Approach 1:
The patent segments the total power allocation into separate maximum uplink power settings for each transmitter and protocol, allowing independent optimization of power for each connectivity interface rather than managing a single pooled power resource
Solution Approach 2:
The system implements self-service power allocation where each transmitter automatically adjusts its own power level based on its specific channel conditions and historical performance data, reducing the complexity of centralized power management for dual connectivity

AI summary
Systems and methods are provided for dynamic power allocation of a first maximum uplink power and a second maximum uplink power, wherein the first maximum uplink power is used by a first transmitter to communicate with a first access point and the second maximum uplink power is used by a second transmitter to communicate with a second access point (dual connectivity). Historical data for a sector and one or more wireless communication devices is collected and analyzed to determine the modification of the first maximum uplink power and the second maximum uplink power.
