Dynamic Uplink Power Control for Wireless Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of high-powered wireless devices into wireless networks can negatively affect uplink system performance due to interference with standard-powered devices, especially when both operate on the same frequency band or sub-band, leading to suboptimal coverage and throughput.
Innovation Solution
Implementing a system where high-powered wireless devices are initially set to a standard transmission power level and only elevated to high power upon identification of high-priority data sessions through packet inspection, using processing nodes to manage and adjust transmission power dynamically via downlink control indicators.

1Area of stationary object
If high-powered wireless devices transmit at high power levels continuously, then coverage and throughput are enhanced, but interference to standard-powered devices increases
Solution Approach 1:
The patent implements dynamic transmission power adjustment where high-powered wireless devices switch between high power mode and standard power mode based on real-time packet inspection results. The system dynamically identifies high-priority data sessions and activates high-powered transmission only during these periods, rather than maintaining continuous high power transmission.
Solution Approach 2:
The system changes the transmission power parameter of high-powered wireless devices based on packet inspection outcomes. When high-priority data sessions are detected, the transmission power is increased to high levels; otherwise, it remains at standard levels, thereby adapting the power parameter to actual network conditions.
2Productivity
If high-powered wireless devices operate in high-powered transmission mode, then throughput is improved, but uplink system performance deteriorates due to interference
Solution Approach 1:
The system dynamically adjusts the operational state of high-powered wireless devices based on packet inspection. High-powered transmission mode is activated only when high-priority data sessions are detected, and deactivated otherwise, creating a dynamic balance between throughput enhancement and system performance maintenance.
Solution Approach 2:
The transmission power parameter is changed based on packet inspection results. The system transitions between power classes (e.g., from power class 3/4 to power class 1/2) depending on whether high-priority data sessions are identified, thereby optimizing throughput while preserving uplink system performance.
3Object-affected harmful factors
If standard transmission power level is used for all devices, then interference is minimized, but coverage and throughput enhancement is limited
Solution Approach 1:
The patent implements a dynamic power management system where the transmission power level is not fixed but adapts based on packet inspection results. Standard power level is the default state that minimizes interference, but the system can dynamically transition to high power mode when high-priority data sessions are detected, thereby achieving both interference minimization and coverage enhancement.
Solution Approach 2:
The system changes the transmission power parameter from standard levels to high levels based on packet inspection outcomes. This selective parameter change allows the network to achieve coverage and throughput enhancement only when necessary, while maintaining low interference conditions during normal operation.

AI summary
Minimizing interference that may potentially be caused by high-powered wireless devices to other wireless devices in the network includes determining that a first wireless device assigned to a first power class is engaged in located in a data session of a first type, and activating a high-powered transmission mode of the first wireless device. The high-powered transmission mode utilizes a first transmission power level that is associated with the first power class.
