US 11,122,566 B2 · Waveform design based on power spectral density (PSD) parameters

Abstract

Wireless communications systems and methods related to communicating in a frequency spectrum using interlaced frequency channels and non-interlaced frequency channels are provided. A first wireless communication device selects a waveform structure between an interlaced frequency structure and a non-interlaced frequency structure for communicating in a frequency spectrum. The first wireless communication device communicates, with a second wireless communication device in the frequency spectrum, a communication signal based on the selected waveform structure. The interlaced frequency structure includes at least a first set of frequency bands in the frequency spectrum, the first set of frequency bands interlacing with a second set of frequency bands in the frequency spectrum. The non-interlaced frequency structure includes one or more contiguous frequency bands in the frequency spectrum.

A method of wireless communication, comprising:

selecting, by a first wireless communication device, an interlaced frequency structure for communicating in a first frequency band of a frequency spectrum based on a power spectral density (PSD) parameter of the frequency spectrum, wherein selecting the interlaced frequency structure based on the PSD parameter of the frequency spectrum comprises selecting between the interlaced frequency structure and a non-interlaced frequency structure based on the PSD parameter;
communicating, by the first wireless communication device with a second wireless communication device in the first frequency band of the frequency spectrum, a first communication signal using a lower subcarrier spacing (SCS) for the selected interlaced frequency structure;
and
communicating, by the first wireless communication device with the second wireless communication device in a second frequency band of the frequency spectrum, a second communication signal using a greater SCS for the non-interlaced frequency structure.
