Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource allocation parameters are precisely specified for GI-based waveforms, then communication performance is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential resource allocation parameters needed for GI-based waveform communication and quantizes them to discrete levels. This selective extraction and quantization reduces the amount of signaling information while maintaining the critical parameters necessary for communication performance.
Solution Approach 2:
The patent transforms continuous resource allocation parameters into discrete quantized parameter sets. By changing the parameter representation from continuous to discrete values, the signaling overhead is reduced while the essential communication performance is preserved through the quantized parameter indication.
2Measurement precision
If detailed resource allocation parameters are transmitted, then communication accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the resource allocation parameters into distinct quantized sets that can be independently selected and indicated. This segmentation allows the system to maintain accuracy for critical parameters while simplifying the overall parameter structure, thereby reducing system complexity.
Solution Approach 2:
The patent applies partial action by providing quantized parameter sets that contain only the necessary level of detail for accurate communication. Rather than transmitting complete detailed parameters, the quantized sets provide sufficient information for communication accuracy while reducing the complexity of parameter management.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more first signals that indicate a resource allocation and that indicate a set of guard interval (GI)-based waveform parameters for a GI-based waveform associated with the UE. The UE may receive, from the network entity, an indication of one or more quantized resource allocation parameters associated with the GI-based waveform. The indication may include one or more formulas for determination of the one or more quantized resource allocation parameters, the one or more quantized resource allocation parameters, or both. The UE may communicate the GI-based waveform with the network entity using the one or more quantized resource allocation parameters and the set of GI-based waveform parameters.
