Wireless communications systems and methods related to scheduling and communicating in a frequency spectrum using interlaced frequency resources are provided. A first wireless communication device communicates, with a second wireless communication device, a first interlace configuration indicating a first set of interlaced frequency resources in a frequency band based on a power spectral density (PSD) parameter. The first wireless communication device communicates, with the second wireless communication device, a first frequency resource exclusion configuration. The first wireless communication device communicates, with the second wireless communication device, a first allocation including at least some frequency resources from the first set of interlaced frequency resources based on the first frequency resource exclusion configuration. The first wireless communication device communicates, with the second wireless communication device, a first communication signal based on the first allocation.
