1. A method performed by an apparatus in a wireless local area network (WLAN), the method comprising:
transmitting a first physical layer convergence protocol (PLCP) protocol data unit (PPDU) having a first variant format and including a first triggered response scheduling control field and a second PPDU having a second variant format and including a second triggered response scheduling control field at the same time in A(aggregated)-PPDU, wherein the second PPDU for the second variant is transmitted in duplicate (DUP) mode in which data in a payload portion of the second PPDU is duplicated in frequency; and
receiving a first response to the first PPDU and a second response to the second PPDU in A-PPDU based on the first triggered response scheduling control field and the second triggered response scheduling control field, respectively,
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.
