Solution Overview
Problem
The increased mobility of mobile users and the expansion of satellite cellular services introduce challenges in managing uplink transmission power due to varying distances and motion between cell towers and user equipment, leading to inefficiencies and user experience issues.
Innovation Solution
A UE transmission attenuation habituation (UTAH) architecture is implemented, where a manager dynamically adjusts uplink transmission power plans based on environmental factors and mobility, predicting future locations of service sources and optimizing power levels to maintain efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink transmission power is increased to maintain connectivity with cell towers, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by predicting future locations of UEs and service sources, and pre-adjusting UTP plans before connectivity issues arise. This allows the system to maintain communication reliability while optimizing power consumption by anticipating future conditions rather than reactively increasing power.
Solution Approach 2:
The system dynamically adjusts uplink transmission power plans based on real-time conditions including UE location, service source locations, battery status, and temperature. This dynamic adaptation allows the system to maintain reliability when needed while reducing power consumption when conditions permit, resolving the contradiction between consistent connectivity and energy efficiency.
2Reliability
If uplink transmission power is increased to compensate for distance and motion, then user experience is improved, but device temperature increases
Solution Approach 1:
The system predicts future UE locations and service source positions in advance, allowing it to pre-adjust transmission power levels before the UE enters conditions that would require high power operation. This prevents temperature buildup while maintaining user experience by ensuring connectivity is already optimized when the UE reaches predicted locations.
Solution Approach 2:
The system changes operational parameters by adjusting UTP plans based on multiple factors including location, velocity, battery status, and temperature. When temperature is high, the system modifies transmission parameters to reduce power levels, thereby cooling the device while maintaining acceptable user experience through intelligent parameter adaptation.
3Productivity
If dynamic management of UTP plans is implemented, then system efficiency is improved, but device complexity increases
Solution Approach 1:
The system introduces a UTP manager as an intermediary component that handles the complexity of dynamic power plan management. This mediator receives inputs from multiple sensors and systems, processes them through prediction algorithms, and outputs adjusted UTP plans. By centralizing the complexity in a dedicated manager rather than distributing it throughout the device, system efficiency is improved while the perceived device complexity is contained and managed.
Solution Approach 2:
The UTP manager performs preliminary computations and predictions in advance, preparing optimized power plans before they are needed. This pre-processing approach improves system efficiency by having ready-to-use optimized plans while reducing the real-time computational burden on the device, effectively managing complexity through time-based separation of computation and execution.

AI summary
Systems and methods are provided for managing uplink transmission power (UTP) plans for user devices. A manager can assess UTP adjustment criteria to determine if an updated UTP plan should be activated for the user device. UTP plans may need to be updated when devices are transmitting too much power or not enough in order to be received by a telecommunications network. Updated UTP plans can increase or decrease the power transmitted by the device.
