HPUE Handover and Power Reduction for Frequency Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power user equipment (HPUE) operating in enhanced power mode causes frequency interference with low-power user equipment (LPUE) in wireless networks, leading to capacity burdens and competition for access nodes, particularly in overlapping cell regions.
Innovation Solution
Implementing a method to detect HPUE in overlapping regions and hand them over to a neighboring access node, while reducing their maximum allowable power to standard mode, thereby minimizing interference and optimizing handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If HPUE operates in enhanced power mode to extend coverage range, then coverage area is improved, but frequency interference to LPUE increases
Solution Approach 1:
The system performs preliminary detection of HPUE devices operating in enhanced power mode within overlap regions before interference occurs. By detecting HPUE in the overlap region and proactively initiating handover or power reduction, the system prevents frequency interference from affecting LPUE communication quality
Solution Approach 2:
The patent implements dynamic power management by reducing the maximum allowable power of detected HPUE from enhanced power mode to standard power mode. This dynamic adjustment allows the system to optimize coverage when needed while minimizing interference when HPUE operates in overlap regions
2Power
If HPUE operates in enhanced power mode to increase transmit power, then signal range is improved, but capacity burden on access node increases
Solution Approach 1:
The access node performs preliminary detection of HPUE in overlap regions before the device consumes excessive capacity resources. By detecting HPUE early and initiating handover to another access node or reducing power, the system prevents capacity burden from accumulating
Solution Approach 2:
The patent extracts HPUE devices from the overloaded serving cell by initiating handover to a target access node. This removes the capacity burden from the original access node while maintaining service continuity for the HPUE device
3Productivity
If HPUE and LPUE share the same frequency band, then spectrum efficiency is improved, but interference between devices increases
Solution Approach 1:
The system performs preliminary detection of HPUE devices in overlap regions before interference with LPUE occurs. By proactively initiating handover or power reduction when HPUE is detected, the system enables safe frequency band sharing without device-to-device interference
Solution Approach 2:
The patent changes the power parameter of HPUE from enhanced power mode to standard power mode when operating in overlap regions. This parameter adjustment allows LPUE and HPUE to share the same frequency band efficiently while preventing harmful interference between devices

AI summary
Exemplary embodiments described herein include systems, methods, and processing nodes for reducing frequency interference in a wireless communication system. A high-power user equipment (HPUE) operating in an enhanced power mode with a first access node can be detected beyond the range of a low-power user equipment (LPUE) or a HPUE operating in a standard power mode. The HPUE can be handed over to a second, neighboring access node. A maximum allowable power of the HPUE can be reduced so that the HPUE is operating in a standard power mode.
