RF Transmission Power Control Using Dual APT Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently managing transmission power for signals across different frequency bands, particularly in supporting higher data transmission rates required by evolving wireless communication systems, which can lead to inefficiencies and potential abnormalities in high-frequency communication components.
Innovation Solution
The electronic device employs a system that identifies specific events and bands, using average power tracking (APT) tables to dynamically adjust transmission power based on whether certain parameters meet conditions, allowing for adaptive power settings through baseband signal magnitude changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If transmission power is increased to support higher data transmission rates, then data transmission rate is improved, but efficiency and reliability of high-frequency communication components deteriorate
Solution Approach 1:
The patent implements dynamic transmission power adjustment by switching between first and second APT tables based on operating conditions. The system dynamically selects which APT table to use depending on whether the first parameter satisfies the first condition, allowing transmission power to adapt in real-time to different frequency bands and operational states, thereby maintaining high data rates while protecting component reliability
Solution Approach 2:
The patent changes the parameter of transmission power by selecting different APT tables (first APT table or second APT table) based on the satisfaction of the first condition. This parameter change mechanism allows the system to adjust transmission power levels appropriately for different frequency bands and operational conditions, resolving the contradiction between high data rates and component reliability
2Reliability
If transmission power is dynamically adjusted based on multiple conditions, then reliability of high-frequency components is improved, but device complexity increases
Solution Approach 1:
The patent segments the power control system into distinct components: first APT table, second APT table, and condition evaluation logic. By dividing the complex power adjustment task into separate manageable segments (different APT tables for different conditions), the system achieves reliable high-frequency communication while keeping each individual component relatively simple and maintainable

AI summary
An electronic device may include: a memory storing instructions; at least one communication processor; and at least one RF circuit configured to process an RF signal based on a signal from the at least one communication processor. The instructions, when executed by the at least one communication processor, may cause the electronic device to: based on identifying a first event, identify whether a band associated with the first event is a first band; based on identifying that the band associated with the first event is the first band, identify whether a first parameter associated with transmission of an RF signal satisfies a first condition; based on identifying that the first parameter satisfies the first condition, set, based on a first APT table, first power as transmission power for the RF signal associated with the first event; and based on identifying that the first parameter does not satisfy the first condition, change, based on a second APT table, the magnitude of a baseband signal transmitted to the RF circuit so as to set second power as transmission power for the RF signal associated with the first event.
