Electronic Device Transmission Power Control with Restricted Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The continuous increase in transmission power control variables based on power control signals from a network, regardless of channel state, leads to unnecessary power consumption and inefficient power management in electronic devices.
Innovation Solution
An electronic device configures transmission power control variables based on designated conditions, restricting unnecessary increases in transmission power, thereby mitigating power consumption by selectively updating power control variables based on channel state and power control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission power control variable continuously increases based on power control signals from the network regardless of channel state, then the transmission power is increased to maintain connection, but unnecessary power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of transmission power control variable update behavior based on channel state conditions. The electronic device transitions between different update modes (continuous update vs. restricted update) depending on whether the channel state satisfies designated conditions, making the power control system adaptive rather than static
Solution Approach 2:
The patent introduces feedback mechanisms where the electronic device monitors channel state conditions and uses this information to control the updating behavior of transmission power control variables. The system receives feedback from the network about channel conditions and adjusts power control variable updates accordingly, preventing unnecessary increases when conditions warrant restriction
2Speed
If the transmission power control variable is frequently updated based on power control signals, then the transmission power responds quickly to network conditions, but power management efficiency decreases
Solution Approach 1:
The system dynamically adjusts the update frequency of transmission power control variables based on channel state conditions. When conditions are favorable, updates are restricted to improve efficiency; when conditions deteriorate, updates can proceed to maintain response capability, creating a dynamic balance between speed and efficiency
Solution Approach 2:
The patent changes the behavior parameter of transmission power control variable updates based on channel state conditions. By switching between different update modes (continuous vs. restricted), the system optimizes the balance between response speed and power management efficiency under different operating conditions
