1. A method comprising:
generating a first aggregated physical layer protocol data unit (PPDU) including a first null data packet (NDP) based on an extremely high throughput (EHT) protocol standard and a second NDP based on an EHT+protocol standard, which is a next generation of the EHT protocol standard; and
transmitting the first aggregated PPDU to at least one second apparatus in a wireless local area network (WLAN) system,
wherein each of the first NDP and the second NDP has a same duration, and the first NDP is transmitted in a first band and the second NDP is transmitted in a second band that is different from the first band.
