1. A method performed by a wireless device functioning as a beamformer station (STA) in a wireless network to perform a sounding procedure, comprising:
wirelessly transmitting a null data packet (NDP) announcement frame in a first frequency band, the NDP announcement frame including a sounding dialog token field where bits B0 and B1 of the sounding dialog token field are set to binary ‘1’ to indicate the NDP announcement frame should be processed as an extremely high throughput (EHT) NDP announcement frame; and
wirelessly transmitting an NDP frame in a second frequency band,
wherein the first and the second frequency bands are separated by at least one Gigahertz (GHz).
