1. An apparatus for a station (STA) or access point (AP), the apparatus comprising memory; and processing circuitry coupled to the memory, the processing circuitry configured to:
transmit a first physical (PHY) protocol data unit (PPDU) on a 42-48 GHz band in accordance with a subcarrier spacing of 2.5 KHz and Discrete Fourier Transform (DFT) period of 0.4 μs, wherein the apparatus is configured to transmit at least on a 160 MHz subchannel, a 320 MHz subchannel, a 640 MHz subchannel, and a 1280 MHz subchannel; and
decode a second PPDU, in response to the first PPDU, on the 42-48 GHz band in accordance with the subcarrier spacing of 2.5 KHz and an inverse DFT period of 0.4 μs.
