Power Amplifier State Control for Discontinuous Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power control methods in wireless communication systems are inefficient in managing power amplifier states during discontinuous transmission modes, leading to unnecessary power consumption when no data is being transmitted.
Innovation Solution
A method that determines whether a transmitter has information to transmit and causes the power amplifier to enter a low power state, with a configurable time delay between the determination and the power state change, allowing for autonomous detection and control of power amplifier states without requiring signaling from a system module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the power amplifier is switched off immediately when no data is transmitted, then power consumption is reduced, but transmission readiness is compromised
Solution Approach 1:
The patent applies preliminary action by maintaining the power amplifier in a low power state for a configurable delay period after determining no data needs transmission. This delay allows the system to prepare for potential upcoming transmissions, ensuring the power amplifier can quickly transition to full power state when data becomes available, thus balancing power savings with transmission readiness.
2Speed
If the power amplifier remains in high power state during idle periods, then transmission readiness is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamics by making the power amplifier's state configurable and adaptive rather than fixed. The system dynamically transitions between high power state and low power state based on transmission needs, with a configurable delay parameter that allows optimization of the balance between power consumption and transmission readiness according to specific application requirements.
3Device complexity
If autonomous detection of transmission needs is implemented, then system complexity is reduced, but detection accuracy may be compromised
Solution Approach 1:
The patent applies self-service by enabling the radio module to autonomously detect whether transmission data is available and independently control the power amplifier's power state. This eliminates the need for external system module signaling, reduces system complexity, and allows the radio module to self-optimize its power consumption based on actual transmission needs.
