Access Repeater UE Distribution Detection Through Induced Responses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access repeater devices face challenges in effectively tracking and maintaining communication with mobile UEs due to their unpredictable movements, leading to inefficiencies in energy transmission and increased power consumption, particularly in 5G environments, and result in reduced signal strength and Quality of Experience (QoE) due to signal attenuation.
Innovation Solution
The access repeater device employs a dynamic power management strategy by periodically reducing its Tx power level to induce UEs to increase their Tx power, allowing for precise detection and optimized energy transmission, thereby improving communication efficiency and reducing power consumption.

Engineering Contradiction Analysis
1Area of stationary object
If the beam of the conventional repeater is widened to cover a broader area, then the likelihood of covering UEs is improved, but the signal strength and range are reduced
Solution Approach 1:
The repeater dynamically adjusts its beam width based on UE distribution information. When UEs are concentrated, the beam is narrowed to maintain high signal strength. When UEs are dispersed, the beam is widened to cover more area. This dynamic adaptation resolves the contradiction between coverage area and signal strength by making the beam characteristics variable rather than fixed.
Solution Approach 2:
The system changes the beam width parameter according to the detected UE distribution. By monitoring UE locations and adjusting the beamforming parameters accordingly, the system optimizes the trade-off between coverage area and signal strength for different operational scenarios.
2Productivity
If the repeater tracks each UE individually and adjusts the beam accordingly, then communication efficiency is improved, but the complexity and resource consumption increase
Solution Approach 1:
Instead of uniformly tracking all UEs with equal resources, the system applies differentiated beamforming strategies based on local UE distribution characteristics. Concentrated UEs receive focused individual tracking, while dispersed UEs are served by broader sector beams, optimizing resource allocation according to local conditions.
Solution Approach 2:
The system segments UEs into different groups based on their spatial distribution patterns. Concentrated UEs are tracked individually with narrow beams, while dispersed UEs are served by wider sector beams. This segmentation reduces overall system complexity by applying different tracking strategies to different UE groups.
3Ease of operation
If the repeater uses wide beam access, then connectivity in proximity is improved, but signal attenuation occurs at greater distances
Solution Approach 1:
The repeater dynamically switches between wide beam and narrow beam modes based on UE distance and distribution. For nearby UEs, wide beams provide easy connectivity. For distant UEs, the system transitions to narrower, more focused beams to overcome signal attenuation, thus adapting to different operational conditions.

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, and detects a distribution of a set of user equipment (UEs), within a physical coverage zone of the access repeater device based on the transmitted first beam of RF signals, where a first UE of the set of UEs is detected at a first distance from the access repeater device. 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 executes a beam splitting operation to concurrently serve the first and second UE based on the first beam of RF signals and a second beam of RF signals.
