RF Data Multiplexer with Power-Matched Output Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fronthaul multiplexers face issues with data overflow and loss during the combining of radio frequency (RF) data due to high power messages from user equipment located at the edge of multiple cell coverages, leading to inefficient data handling.
Innovation Solution
A multiplexer with output management circuits that manage and combine RF data by comparing power levels and determining if they match a default rule, discarding data at risk of overflow and reducing data loss through a combine circuit, while also incorporating decompression and compression circuits to handle compressed data and generate combined RF data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the FHM combines RF data from multiple RUs, then data diversity is improved, but data overflow and loss occur due to high power messages
Solution Approach 1:
The output management circuit performs preliminary power level comparison and determination before the combining operation. By evaluating whether power levels match the default rule in advance, the system prevents overflow conditions from occurring during the combine operation, thus maintaining reliability while enabling data diversity.
Solution Approach 2:
The output management circuit acts as an intermediary between the individual RU data streams and the combine circuit. It mediates the data flow by selectively forwarding or discarding data based on power level assessment, preventing harmful high-power messages from reaching the combine circuit and causing overflow.
2Quantity of substance
If the FHM combines all received RF data, then complete data collection is achieved, but overflow occurs reducing data quality
Solution Approach 1:
The system applies different handling rules to different data streams based on their local power level characteristics. The output management circuit assesses each data stream's power level and applies selective forwarding or discarding rules locally, ensuring that only data meeting quality criteria (power matching default rule) are combined, thus maintaining data quality while collecting complete valid data.
Solution Approach 2:
The system changes the parameter of data inclusion based on power level assessment. By dynamically determining whether to forward or discard data streams based on their power levels relative to the default rule, the system ensures that only data within acceptable parameter ranges are combined, maintaining data quality while achieving complete collection of valid data.

AI summary
A multiplexer and a method for combining radio frequency (RF) data are provided. The method is described below. The first output management circuit receives first data and second data and determines whether a first power of the first data and a second power of the second data match a default rule. The first output management circuit output first output data including the second data to a combine circuit coupled to the first output management circuit in response to the first power and the second power not matching the default rule. The combine circuit receives multiple output data from the output management circuits respectively and combines the output data to output combined RF data. The output management circuits include the first output management circuit. The output data includes the first output data.
