1. A method performed by an apparatus in a wireless local area network (WLAN), the method comprising:
transmitting a first null data packet (NDP) Announcement physical layer convergence protocol (PLCP) protocol data unit (PPDU) compliant with a first variant and a second NDP Announcement PPDU compliant with a second variant at the same time in aggregated-PPDU (A-PPDU) transmission, wherein the first NDP Announcement PPDU compliant with the first variant and the second NDP Announcement PPDU compliant with the second variant have a same time duration and are transmitted in different frequency bands; and
transmitting at least one Sounding NDP compliant with the first variant for both at least one first station (STA) compliant with the first variant and at least one second STA compliant with the second variant a predetermined time after the first NDP Announcement PPDU compliant with the first variant and the second NDP Announcement PPDU compliant with the second variant are transmitted at the same time in A-PPDU transmission,
wherein the first variant is based on a first protocol standard and the second variant is based on a second protocol standard, and
wherein the second protocol standard is beyond version of the first protocol standard.
