Base Station Signal Decoding via Quality Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for filtering out signals from mobile stations in cellular networks require significant data transfer between base stations and a central processing unit, leading to high network resource usage and costly infrastructure needs.
Innovation Solution
The method involves determining signal quality at each base station and selecting a suitable base station for processing and decoding, reducing unnecessary data transmission by only forwarding necessary signal information to the decision device, which can be centralized or decentralized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all superimposed signals from multiple base stations are digitized and transmitted to a central processing unit for signal filtering and decoding, then the wanted signal can be accurately extracted from mobile stations, but the data transfer volume increases significantly and network resources are heavily stressed
Solution Approach 1:
The patent extracts and transmits only the essential signal quality parameters (such as signal strength, interference levels, and channel conditions) from each base station to the decision device, rather than transmitting complete digitized superimposed signals. This selective extraction of critical information maintains the ability to determine signal quality and select optimal base stations while dramatically reducing the data transfer volume and network resource consumption.
Solution Approach 2:
The patent segments the signal processing function by separating the decision-making process from the signal processing process. The decision device receives only necessary quality parameters from multiple base stations to determine signal quality and select the optimal base station, while the actual signal filtering and decoding are performed locally at the selected base station. This segmentation eliminates the need to transmit large volumes of signal data to a central unit.
2Extent of automation
If a central processing unit is used to process and decode superimposed signals from all base stations, then signal decoding can be centralized and coordinated, but further transmission capacity must be installed, bought or rented which is very costly
Solution Approach 1:
The patent enables base stations to perform signal filtering and decoding operations locally after being selected by the decision device, rather than requiring all signals to be processed at a centralized unit. Each base station uses its own processing capabilities to extract and decode wanted signals from the superimposed signals it receives, reducing the need for expensive centralized processing infrastructure and additional transmission capacity.
3Quantity of substance
If signal quality is determined for each base station and only necessary information is transmitted to a decision device, then data transfer volume is reduced and network resources are less stressed, but the selection of the optimal base station must be accurately performed
Solution Approach 1:
The patent performs preliminary determination of signal quality parameters at each base station before transmission to the decision device. Each base station pre-processes its received signals to extract relevant quality metrics (signal strength, interference, channel conditions) and transmits only these processed parameters. This preliminary action ensures that the decision device receives sufficient information to accurately select the optimal base station while minimizing data transfer requirements.

AI summary
A method for filtering out a useful signal of a mobile radio terminal from a plurality of superimposed signals having a signal quality received by base stations in a cellular mobile radio network. The superimposed signal of the mobile radio terminal is detected by base stations that are reached and the signal quality of the received and superimposed signal of every base station reached is determined. The signal quality of a selected base station is then transmitted to a decision element and a selection of a selected base station is made by the decision element to decode the useful signal of the mobile radio terminal. The invention also relates to a device for filtering out a useful signal of a mobile radio terminal from a plurality of superimposed signals received by base stations in a cellular mobile radio network.
