Abstract: The present disclosure provides methods and apparatuses for wireless communications. In some embodiments, a wireless communication method of a first device includes receiving a physical layer protocol data unit (PPDU) from a second device, and identifying a channel bandwidth of the PPDU based on a first field and a second field related to the channel bandwidth of the PPDU. The first field and the second field are extracted from a signal field included in the PPDU.

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.

Abstract: Disclosed is a method of transmitting a message for measuring a distance between a first terminal and a second terminal that are positioned in a basic service set (BSS), and in this case, the first terminal transmits a fine timing measurement (FTM) request frame for beginning of measurement of a distance to second terminal. The first terminal receives an Ack frame for the FTM request frame from the second terminal. The first terminal transmits a first data frame to the second terminal, by the first terminal. The first terminal receives a first Ack frame for the first data frame from the second terminal, by the first terminal. The first terminal transmits a second data frame but not the FTM frame to the second terminal. The first terminal receives a second Ack frame for the second data frame from the second terminal.
