Uplink Power Adjustment for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with high data transmission demands, such as gaming or video streaming, electronic devices experience abnormal phenomena like great delays, network lag, or call failures due to insufficient uplink data transmission power.
Innovation Solution
The method involves detecting whether certain information meets a preset condition, including retransmission rate, actual transmission power, and maximum transmission power, and then using a power control algorithm to adjust the maximum transmission power to a target power that is greater than the initial but within the device's inherent maximum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device configures a maximum uplink power for the electronic device according to antenna radiation capability and interference considerations, then the network interference is reduced and radiation safety is improved, but the transmission performance deteriorates due to insufficient power in high-demand scenarios
Solution Approach 1:
The patent implements dynamic power adjustment by allowing the electronic device to autonomously increase its uplink transmission power from the configured maximum power when transmission performance degrades. The power control module adjusts the power dynamically based on real-time transmission conditions, transforming the static power configuration into a dynamic adaptation mechanism that resolves the contradiction between maintaining network reliability and achieving high transmission productivity.
Solution Approach 2:
The patent changes the power parameter from a fixed configured value to an adjustable range. When transmission performance metrics (such as retransmission rate or throughput) indicate degradation, the system modifies the transmission power parameter upward within the device's inherent maximum limits. This parameter change enables the system to adapt to varying transmission demands while operating within safe radiation and interference constraints.
2Object-affected harmful factors
If the electronic device uses the configured maximum uplink power for transmission, then the radiation safety and network interference control are maintained, but transmission delays and network lag occur in high-demand scenarios
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device monitors transmission performance indicators (such as retransmission rates, throughput, or latency metrics) and uses this feedback to determine when to increase transmission power. The power control module continuously receives feedback about transmission quality and adjusts power accordingly, creating a closed-loop control system that reduces transmission delays while maintaining interference control through selective power adjustment rather than continuous maximum power usage.
Solution Approach 2:
The patent enables the electronic device to take preliminary action by proactively increasing transmission power before severe transmission failures occur. When performance metrics indicate degradation trends, the system preemptively adjusts power upward to prevent complete transmission failures, call drops, or excessive delays, thereby maintaining reliable communication without needing to operate at maximum power continuously.
3Productivity
If the electronic device increases transmission power to meet high data transmission demands, then the transmission rate and responsiveness improve, but the radiation safety and network interference control may be compromised
