Solution Overview
Problem
Existing wireless communication technologies face challenges in supporting multiple waveforms within a single device due to increased complexity and overheads, as different waveforms like CP-OFDM and CPM exhibit trade-offs in spectral efficiency and power efficiency, making it difficult to meet diverse 6G KPIs across various use cases.
Innovation Solution
A unified and configurable waveform framework that includes reusable components and bypassable components, controlled by switches, allowing for the generation of multiple waveforms such as CP-OFDM, f-OFDM, DFT-s-OFDM, and GFDM, by configuring or bypassing these components to meet specific requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate waveform generation systems are implemented to support different waveforms (CP-OFDM, CPM, etc.), then waveform versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal waveform generation framework where a single apparatus can generate multiple different waveforms (CP-OFDM, CPM, f-OFDM, DFT-s-OFDM, GFDM) by configuring and bypassing specific components. The reusable components (modulation module, IFFT module, subcarrier mapper, CP insertion module) serve multiple waveform generation functions, eliminating the need for separate dedicated systems for each waveform type.
Solution Approach 2:
The waveform generation system is divided into modular reusable components and bypassable components. Each component performs a specific function (modulation, IFFT, subcarrier mapping, CP insertion) that can be independently configured or bypassed depending on the desired waveform type, allowing flexible composition of different waveform generation paths within a unified framework.
2Adaptability or versatility
If waveform-specific components are added to support diverse 6G KPIs, then adaptability to different use cases is improved, but overhead and processing burden increase
Solution Approach 1:
The system dynamically configures waveform generation by selectively bypassing or activating specific components based on the required waveform type and use case requirements. The bypassable components (filter for f-OFDM, FFT module and frequency domain pulse shaping module for DFT-s-OFDM and GFDM) can be dynamically enabled or disabled through switching mechanisms, allowing the system to adapt to different 6G KPIs without permanently incorporating all possible waveform-specific components.
3Device complexity
If reusable components are shared across multiple waveform types, then device complexity is reduced, but waveform-specific performance optimization may be compromised
Solution Approach 1:
The system segments waveform generation into reusable core components and bypassable waveform-specific components. The reusable components handle common functions shared across all waveform types, while the bypassable components provide waveform-specific processing when needed. This segmentation allows the system to maintain low complexity through component reuse while preserving waveform-specific performance optimization through selective activation of specialized components.
Solution Approach 2:
The switching mechanism acts as an intermediary that selectively routes signals through appropriate processing paths. When waveform-specific performance is required, the switch activates the corresponding bypassable component; when general-purpose waveform generation suffices, the switch bypasses these components, thus mediating between complexity reduction and performance optimization based on operational requirements.

AI summary
Aspects of the present disclosure provide an apparatus that is configured to generate a variety of waveforms. For example, the apparatus can include a plurality of reusable components that are coupled in series with each other. The reusable components can be configurable to generate a first waveform. The apparatus can also include a bypassable component coupled in series with the reusable components. The bypassable components can be bypassable, or be configurable to operate with the reusable components to generate a second waveform different from the first waveform. The apparatus can also include a bypassing controlling component coupled to the reusable components and the bypassable component. The bypassing controlling component can be either configured such that the bypassable component is bypassed and the reusable components generate the first waveform, or configured such that the bypassable component is passed and the bypassable component and the reusable components generate the second waveform.
