Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling power amplifiers in GSM Base Stations fail to improve energy efficiency when timeslots are occupied, leading to inefficient energy consumption.
Innovation Solution
A method that adjusts the working voltage of the power amplifier based on power control information obtained for the next timeslot, using techniques such as dual power supply switching or Pulse-Width Modulation to optimize voltage levels for reduced energy consumption without affecting RF output indexes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the PA working state is adjusted by controlling the grid voltage of the PA when timeslots are idle, then the energy consumption of the GSM BS is reduced, but the energy efficiency cannot be improved when the timeslots are occupied
Solution Approach 1:
The patent implements dynamic adjustment of the PA working voltage based on real-time detection of timeslot occupation status and power control information. The control unit dynamically switches between different voltage levels (e.g., high voltage for occupied timeslots, low voltage for idle timeslots) to optimize energy consumption across varying operational conditions, making the energy management system adaptive rather than static
Solution Approach 2:
The patent changes the operating parameters of the PA by adjusting the working voltage level according to power control information from different timeslots. By varying the voltage parameter dynamically (rather than maintaining a fixed voltage), the system achieves both energy reduction during idle periods and maintains performance during occupied periods, resolving the contradiction between energy savings and adaptability
2Use of energy by stationary object
If the PA is cut off at idle timeslots to reduce static power consumption, then the energy consumption is reduced, but the system cannot respond efficiently to power control information during occupied timeslots
Solution Approach 1:
The control unit obtains power control information for the next timeslot in advance and prepares the appropriate working voltage level before the timeslot begins. This preliminary preparation ensures that when the timeslot starts, the PA is already configured with the correct voltage level, enabling immediate response without delay
Solution Approach 2:
The system maintains dynamic readiness by continuously monitoring power control information and adjusting the PA working voltage in real-time based on occupation status. This dynamic operation allows the PA to transition quickly between idle and occupied states, maintaining fast response capability while minimizing static power consumption during idle periods
