Access Repeater Beam Power Modulation for Mobile UE Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access repeater devices face challenges in maintaining efficient communication with mobile UEs due to unpredictable movement, high power consumption, and signal attenuation, especially in 5G and mmWave environments, leading to inefficiencies and reduced Quality of Experience (QoE).
Innovation Solution
The access repeater device employs a dynamic power management strategy by periodically lowering its Tx power level to induce UEs to increase their Tx power, allowing for precise detection and optimized energy transmission, reducing power consumption, and enhancing communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access repeater device uses a narrow beam to maintain signal strength and range, then communication reliability is improved, but the ability to detect and track unpredictable mobile UEs deteriorates
Solution Approach 1:
The patent applies dynamics by making the beam width adjustable rather than fixed. The access repeater device dynamically changes between narrow and wide beam configurations based on UE mobility characteristics. When UEs are stationary, a narrow beam maintains signal strength; when UEs move unpredictably, the beam width is increased to improve detection capability, thus resolving the contradiction between reliability and adaptability
Solution Approach 2:
The patent changes the beam width parameter dynamically based on detected UE mobility patterns. By monitoring UE positions and movement characteristics, the system adjusts the beam width parameter to optimize both signal strength for stationary UEs and detection capability for mobile UEs, resolving the technical contradiction
2Adaptability or versatility
If the access repeater device widens the beam to cover broader areas and track mobile UEs, then detection capability is improved, but signal strength and transmission range deteriorate
Solution Approach 1:
The system dynamically adjusts beam width based on real-time UE detection. When mobile UEs are detected, the beam is widened to improve coverage and detection capability. When UEs are stationary or in predictable locations, the beam is narrowed to concentrate signal strength, thus resolving the contradiction between detection capability and signal strength
3Length of stationary object
If 5G-enabled UEs increase Tx power to extend communication range, then communication coverage is improved, but power consumption and battery depletion accelerate
Solution Approach 1:
The patent implements feedback mechanisms where the access repeater device monitors received signal strength from UEs and adjusts its own Tx power accordingly. This feedback loop allows the system to maintain communication coverage by optimizing power levels dynamically, preventing unnecessary high power consumption while ensuring adequate signal strength for reliable communication
Solution Approach 2:
The system changes the Tx power parameter dynamically based on distance and signal conditions. Rather than maintaining high power continuously, the access repeater adjusts power levels based on real-time signal quality measurements, reducing overall power consumption while maintaining communication range when needed

AI summary
An access repeater device that controls transmission of a first beam of radio frequency (RF) signals at a first transmit (Tx) power level. The access repeater device controls decrease of the first Tx power level of the first beam of RF signals to induce a UE response at a second UE to increase a Tx radio power of an RF signal by the second UE. The access repeater device identifies that the second UE responds to the first beam of RF signals communicated in a test direction from a plurality of different test directions and modulates a transmit power output of the first beam of RF signals towards the second UE in the test direction.
