Wireless Transmitter Power Control Based on User Data Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmission power management, particularly when user data is not being transmitted, leading to wasted power and reduced performance over time.
Innovation Solution
A method and apparatus that dynamically control transmission power based on the presence or absence of user data and the type of transmission signal, adjusting power levels and timing to optimize power usage and prevent unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission power is maintained at high levels continuously, then transmission reliability is improved, but energy consumption increases and power efficiency deteriorates
Solution Approach 1:
The patent implements dynamic transmission power control by adjusting power levels based on real-time detection of user data allocation status. The base station transitions from static high-power transmission to dynamic power adjustment, maintaining high power only when user data is actively transmitted and reducing power when no user data is present, thereby resolving the contradiction between transmission reliability and energy consumption
Solution Approach 2:
The patent changes the transmission power parameter dynamically based on the presence or absence of user data allocation. By detecting whether user data is allocated and adjusting the power parameter accordingly (high power when allocated, reduced power when not allocated), the system optimizes both transmission reliability and energy efficiency
2Reliability
If transmission power is continuously maintained, then transmission performance is preserved, but power waste increases during idle periods
Solution Approach 1:
The patent implements a feedback mechanism where the base station detects whether user data is allocated and uses this information to control transmission power. The detection result feeds back to the power control module, creating a closed-loop system that adjusts power levels based on actual transmission needs, thereby eliminating power waste during idle periods while maintaining performance when needed
Solution Approach 2:
The system performs self-adjustment of transmission power by automatically detecting user data allocation status and controlling power levels without external intervention. The base station monitors its own transmission state and adjusts power accordingly, reducing waste during idle periods while maintaining performance during active transmission
3Reliability
If high transmission power is used continuously, then signal quality is improved, but system lifespan decreases due to increased aging
Solution Approach 1:
The patent implements periodic adjustment of transmission power based on the periodic detection of user data allocation status. Instead of continuous high-power operation, the system alternates between high power (when user data is allocated) and reduced power (when no user data is present), reducing cumulative stress on transmission components and extending system lifespan while maintaining signal quality when needed

AI summary
A method and apparatus of controlling transmission power in a transmitter of a wireless communication system are provided. The method includes generating a first signal to be transmitted to a receiver, identifying whether user data is allocated to the generated first signal, determining transmission power based on a result of the determination, and transmitting a second signal to the receiver, based on the determined transmission power and the first signal.
