Abstract: A method includes 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 a second apparatus in a wireless local area network (WLAN) system. 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.
