Distributed Inverse Physical Layer Processing for Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital telecommunications systems face high calculation power requirements at base stations due to the large number of inverse processing operations needed to receive radiofrequency signals from multiple terminals, which can lead to increased complexity and costs.
Innovation Solution
The distribution of inverse physical layer processing between partial stations and a processing server, where partial stations form intermediate data from radiofrequency signals and the server extracts binary data, reduces the computational load on base stations and enables improved performance by centralizing certain processing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If base stations perform all inverse physical layer processing operations locally, then processing completeness is ensured, but calculation power requirements and device complexity increase significantly
Solution Approach 1:
The patent segments the inverse physical layer processing into two distinct parts: a first part executed by the base station (partial station) and a second part executed by a remote processing server. This segmentation reduces base station complexity while ensuring complete processing through coordinated execution across distributed components.
Solution Approach 2:
The patent introduces a processing server as an intermediary component that handles the second part of inverse physical layer processing. This intermediary receives intermediate data from the base station, completes the processing, and returns results, thereby reducing base station complexity while maintaining processing completeness.
2Ease of operation
If base stations perform all inverse physical layer processing operations locally, then processing autonomy is maintained, but calculation power consumption increases
Solution Approach 1:
The patent segments processing tasks between base stations and a centralized server, with base stations performing only the first part of inverse physical layer processing. This reduces calculation power consumption at base stations while maintaining operational autonomy through distributed execution of processing tasks.
Solution Approach 2:
The patent merges the base station's processing capabilities with those of a centralized server, combining local execution of the first processing part with server-based execution of the second part. This distributed architecture reduces energy consumption at individual base stations while maintaining overall processing autonomy.

AI summary
An access network for terminals of a digital telecommunications system includes base stations adapted for receiving radiofrequency signals emitted by the terminals, each terminal a physical layer processing module adapted to form a radiofrequency signal on the basis of binary data in accordance with a predefined physical layer protocol. Moreover, for at least one base station, termed the “partial station”, an inverse physical layer processing, making it possible to extract binary data from a radiofrequency signal, is distributed between the partial station and a processing server distinct from the partial station, an inverse physical layer processing module being made up of a first inverse processing module, integrated into the partial station, and a second inverse processing module, integrated into the processing server. The invention also relates to a method of digital telecommunications.
