Abstract

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.
