Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in transmitting multiple spatial components over a hybrid fiber coax (HFC) transmission medium, leading to issues with receiver discrimination and the impact of linear or non-linear errors.
Innovation Solution
The solution involves spatially combining multiple 5G new radio (NR) carrier signals by imparting respective channel components that modify the amplitude, phase shift, and/or time delay of each baseband or carrier signal, allowing multiple spatial components to be stacked and distinguished within a common HFC frequency channel.

Engineering Contradiction Analysis
1Productivity
If multiple spatial components are combined onto a single HFC frequency channel, then spectrum efficiency and capacity are improved, but receiver discrimination ability and signal quality deteriorate
Solution Approach 1:
The patent applies preliminary action by imparting distinct channel characteristics (amplitude, phase shift, time delay) to each spatial component before combining them onto the HFC frequency channel. This pre-processing ensures that the spatial components remain distinguishable to the receiver after transmission, resolving the contradiction between high spectrum efficiency and maintained receiver discrimination ability.
2Productivity
If multiple spatial components are transmitted over HFC medium, then transmission capacity is improved, but linear and non-linear transmission medium errors increase
Solution Approach 1:
The patent applies preliminary anti-action by introducing distinct channel characteristics to each spatial component before transmission, which pre-compensates for potential linear and non-linear transmission medium errors. This allows the receiver to better discriminate between spatial components even in the presence of transmission errors, maintaining reliability while achieving high transmission capacity.
3Measurement precision
If channel characteristics are imparted to distinguish spatial components, then receiver discrimination is improved, but signal processing complexity increases
Solution Approach 1:
The patent applies local quality by imparting specific channel characteristics (amplitude, phase shift, time delay) tailored to each individual spatial component. This localized differentiation enables the receiver to distinguish between spatial components using standard processing techniques, improving discrimination without requiring complex overall signal processing.

AI summary
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for spatially combining a plurality of 5G new radio (NR) carrier signals or channels for transport via a common frequency channel through a hybrid fiber coax (HFC) or other communications medium link or network. To overcome a loss of receiver ability to discriminate/process individual spatial components, each baseband signal and/or carrier signal including a spatial component has imparted to it a respective channel component Øn configured to modify amplitude, phase shift, and/or time delay of the baseband signal and/or carrier signal such that multiple spatial component bearing signals stacked/combined within a HFC frequency channel or slot include channel characteristics sufficiently distinct so as to enable a receiver to identify, discriminate, and otherwise process desired spatial components.
