Aggregate Transmit Power Limiting for Multi-Transmitter Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices with multiple transmitters face challenges in managing aggregate transmission power to avoid exceeding regulatory limits, which can lead to reduced signal quality when power is cut back indiscriminately during concurrent operations.
Innovation Solution
A controller in the communication device monitors transmission characteristics and determines if a human is within proximity, triggering a reduced transmit power mode by selecting transmitters based on priority, communicating power levels to network nodes, or assigning all traffic to one transmitter to maintain compliance with power thresholds and mitigate communication quality degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If power cut back is applied indiscriminately to avoid exceeding regulatory limits, then aggregate transmission power is reduced, but signal quality on affected transmit channels is reduced
Solution Approach 1:
The patent applies different power control strategies to different transmitters based on their individual characteristics, traffic priorities, and channel conditions. Instead of uniform power reduction, each transmitter's power is adjusted locally according to its specific needs and the importance of its communication channel, thereby maintaining overall signal quality while reducing aggregate power.
Solution Approach 2:
The system dynamically adjusts transmitter power levels based on real-time conditions including human proximity detection, current power levels, and communication requirements. The power control is not static but adapts continuously to changing conditions, allowing the system to optimize between power reduction and signal quality maintenance based on current operational context.
2Adaptability or versatility
If multiple transmitters operate concurrently at full power, then communication functionality is enhanced, but regulatory power limits may be exceeded
Solution Approach 1:
The system performs preliminary detection of human proximity before allowing full concurrent transmission. By detecting the presence of humans in advance, the system can pre-adjust power levels or prevent certain transmissions from occurring, thereby avoiding regulatory limit violations before they happen while still maintaining communication functionality when safe.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors aggregate power levels, human proximity, and transmission characteristics. Based on this feedback, the controller dynamically adjusts transmitter power to ensure regulatory compliance is maintained while preserving communication functionality. The feedback loop allows real-time optimization of the trade-off between functionality and power limits.

AI summary
A communication device, method, and computer program product provide communication quality mitigations for concurrently-transmitting transmitters of the multiple transmitter communication device. A controller is communicatively coupled with first and second transmitters. The controller executes a transmit power control utility that enables the communication device to monitor transmission characteristics of first and second transmitters. The controller determines whether a human is within a proximity threshold distance to the first and second transmitters. In response to determining that the human is within the proximity threshold distance, the controller determines whether concurrent transmissions by the first and second transmitters have an aggregated power level that exceeds a power threshold. In response to determining that the aggregated power level exceeds the power threshold, the controller triggers operation in a reduced transmit power mode that reduces the aggregate power level to not exceed the power threshold and that includes communication quality mitigation.
