Abstract: This application relates to the field of WLAN technologies, and in particular, to a null data physical layer protocol data unit transmitting method and an apparatus, and may be used in a wireless communication system that supports the 802.11be standard or the EHT standard. In the method, a first device transmits a sensing NDPA frame, where the sensing NDPA frame indicates to transmit an NDP; and then, the first device transmits the NDP, where the NDP is a first NDP or a second NDP. A physical layer version of the first NDP is different from a physical layer version of the second NDP. Correspondingly, a second device receives the sensing NDPA frame and the NDP from the first device.

Abstract: This application relates to the wireless communication field, and is applied to a wireless local area network that supports the 802.11be standard. In particular, this application relates to a method including: An access point AP sends a trigger frame, where the trigger frame is used for triggering a station to send an extremely high throughput trigger based physical layer protocol data unit EHT TB PPDU. The station determines, based on one or two of a value indicated by an uplink EHT spatial reuse parameter UL EHT SRP and a value indicated by one or more uplink spatial reuse parameter UL SRP fields in a common information field of the trigger frame, a value indicated by a spatial reuse parameter SRP in a universal signal field U-SIG of the EHT TB PPDU. The STA sends the EHT TB PPDU to the AP.

Abstract: The present disclosure relates to methods and apparatuses for determining transmit power in a wireless local area network. In an example method, a station receives a trigger frame, where the trigger frame indicates a first resource unit allocated to the station. The trigger frame includes an access point (AP) transmit power subfield and an uplink target receive power subfield. The station sends a trigger-based physical layer protocol data unit (TB PPDU) at first transmit power. The TB PPDU occupies a second resource unit included in the first resource unit. The first transmit power is determined based on an indication of the AP transmit power subfield, an indication of the uplink target receive power subfield, the second resource unit, and the first resource unit.
