Abstract: A method of a first device communicating with at least one second device in a wireless local area network (WLAN) system includes the first device generating a null data packet announcement (NDPA) frame and transmitting the NDPA frame to the at least one second device. The generating of the NDPA frame includes identifying a protocol version of the at least one second device and the NDPA frame includes an NDPA version subfield generated based on the protocol version.

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: A second apparatus for wireless communication includes: a transceiver; and a processing circuit configured to receive, from a first apparatus via the transceiver, a physical layer protocol data unit (PPDU) including a first signal field having a fixed length and a second signal field having a variable length. The second signal field includes an orthogonal frequency-division multiplexing (OFDM) symbol block including at least one OFDM symbol, and one or more repetitions of the OFDM symbol block.

Abstract: The present disclosure provides a wireless communication method. The wireless communication method includes a first device used to negotiate a buffer size with a second device, provide data including a duration field to the second device, and receive a first block acknowledgement from the second device. The first block acknowledgement may include a first block acknowledgement bitmap. The duration field included in the data from the first device may include an indication of a duration associated with the first block acknowledgment that is less than an upper bound duration associated with a second block acknowledgement that includes a second block acknowledgement bitmap with a maximum length.
