Zusammenfassung:	A method performed by an apparatus in a wireless local area network (WLAN) is provided. The method includes: transmitting a first NDP Announcement frame for a first variant and a second NDP Announcement frame for a second variant in A-PPDU transmission, wherein the first NDP Announcement frame for the first variant and the second NDP Announcement frame for the second variant have a same time duration and are transmitted in different frequency bands; and transmitting at least one Sounding NDP for the first variant for both at least one first STA for the first variant and at least one second STA for the second variant, 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.
