Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional signaling methods are used in 5G/NR systems, then system complexity is reduced, but the ability to accommodate varying services and applications with different requirements deteriorates
Solution Approach 1:
The patent implements dynamic signaling where the spectral extension index and frequency domain spectral shaping type index are determined and transmitted for each transmission time interval based on current system conditions and service requirements. This allows the signaling to adapt dynamically to varying services and applications while maintaining manageable complexity through structured index-based control.
Solution Approach 2:
The patent changes signaling parameters by introducing spectral extension index and frequency domain spectral shaping type index as configurable parameters that can be adjusted according to different service requirements. These parameter changes enable flexible accommodation of various services without requiring complete redesign of the signaling framework.
2Reliability
If spectral extension and frequency domain spectral shaping are applied, then PAPR performance is improved, but signaling overhead increases
Solution Approach 1:
The patent uses index values as intermediaries to convey spectral extension and frequency domain spectral shaping configuration information. Instead of transmitting detailed configuration data, the system transmits compact index values that reference pre-defined spectral shapes and extension ratios, significantly reducing signaling overhead while maintaining the ability to achieve improved PAPR performance.
3Adaptability or versatility
If dynamic configuration of spectral extension ratios and frequency domain spectral shaping values is implemented, then service flexibility is improved, but processing complexity increases
Solution Approach 1:
The patent segments the spectral shaping configuration into discrete, manageable components represented by indices. The spectral extension ratio and frequency domain spectral shaping type are divided into separate index parameters that can be independently determined and configured. This segmentation reduces processing complexity by breaking down the configuration task into smaller, more manageable steps while maintaining service flexibility.

AI summary
Methods and apparatuses for signaling pulse shaping in a wireless communication system. A method of BS includes determining a spectral extension index (SEIndex) and a frequency domain spectral shaping type index (FDSSTypeIndex) for at least one transmission time interval (TTI) and transmitting, to a UE, the SEIndex and the FDSSTypeIndex. The method further includes receiving, from the UE, uplink (UL) data based on a spectral extension (SE) ratio associated with the SEIndex and frequency domain spectral shaping (FDSS) values. The FDSS values are associated with the FDSSTypeIndex.
