Partial Downlink Repeater Selecting Critical Signal Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication networks face challenges in enhancing downlink signal reception quality, particularly for mobile devices experiencing interference and poor reception due to the need to transmit entire signals, which leads to energy inefficiency and increased interference.
Innovation Solution
A partial repeater system that selectively transmits critical regions of the downlink signal, using a controller to identify and regenerate only essential portions, thereby reducing unnecessary transmission and minimizing interference to devices that do not require the full signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a repeater transmits the entire downlink signal to enhance reception quality, then the reception quality for mobile devices is improved, but energy consumption increases and interference is generated for devices that do not require the full signal
Solution Approach 1:
The downlink signal is divided into critical regions (containing essential information such as control channels and reference signals) and non-critical regions. The repeater selectively amplifies and retransmits only the critical regions to mobile devices that require signal enhancement, thereby reducing energy consumption while maintaining reception quality.
Solution Approach 2:
Different portions of the downlink signal are treated differently based on their importance. Critical regions are amplified and retransmitted, while non-critical regions are either not transmitted or transmitted with reduced power, optimizing energy usage while ensuring essential signal components reach mobile devices.
2Reliability
If a repeater transmits the entire downlink signal, then all mobile devices receive enhanced signal, but interference is increased for devices that do not require repetition
Solution Approach 1:
The harmful full-signal transmission is replaced by extracting and retransmitting only the critical regions of the downlink signal. This extraction approach ensures that mobile devices receiving the repeated signal get the essential information needed for reliable communication, while minimizing interference to other devices that can directly receive the full signal from the base station without repetition.
3Area of stationary object
If a repeater transmits the entire downlink signal, then comprehensive coverage is provided, but energy efficiency is reduced
Solution Approach 1:
Instead of transmitting the complete downlink signal (excessive action), the repeater transmits only the critical regions that are essential for reliable communication (partial action). This partial transmission approach maintains effective coverage for mobile devices that need signal enhancement while significantly improving energy efficiency by avoiding redundant transmission of non-critical signal portions.
