Abstract
A method for channel sounding for high efficiency (HE) and extreme high throughput (EHT) stations (STAs) includes receiving, by a station (STA), an aggregate physical layer protocol data unit (A-PPDU) from an access point (AP), the A-PPDU including an HE sounding null data packet (NDP) and an EHT sounding NDP, receiving, by the STA, a beamforming report poll frame (BFRP) from the AP, and receiving, by the STA, one or more compressed beamforming (BF)/channel quality indicator (CQI) frames. The HE sounding NDP or the EHT sounding NDP overlaps 242-tone resource units (RUs) corresponding to bits with a value of 1 in the bitmap of the TXVECTOR parameter INACTIVE_SUBCHANNELS or overlaps a punctured center 26-tone RU of an HE sounding NDP, the HE sounding NDP or the EHT sounding NDP being punctured.
