Abstract
Aspects relate to an inverse discrete Fourier transform (IDFT) size that is based on a power-of-two. In some examples, a first apparatus may send an indication of an IDFT size to a second apparatus. In some examples, the first apparatus and/or the second apparatus may output (e.g., transmit) or obtain (e.g., receive) a transmission based on the IDFT size. In some examples, the first apparatus and/or the second apparatus may generate the transmission based on a circular shift, within a frequency allocation, of successive resource block inputs for an IDFT.

A method for communication at a wireless node, the method comprising:
- outputting a first indication of an inverse discrete Fourier transform (IDFT) size, the IDFT size being based on a power-of-two;
- and
- outputting or obtaining a first transmission based on the IDFT size.
