Abstract: An AP sends a trigger frame, where the trigger frame is used to trigger a station to send an EHT TB PPDU; and the AP receives the EHT TB PPDU sent by the station. A common information field of the trigger frame includes four UL SRP fields, indicating a sum of transmit power of the AP and maximum interference power accepted by the AP. Values indicated by an SRP1 field and an SRP2 field in a U-SIG of the EHT TB PPDU are respectively determined based on values indicated by the four UL SRP fields.

Abstract: A method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a data field; and sending the PPDU to a first station and a second station, where the first station is a station that does not support receiving a midamble, and the second station is a station that supports receiving the midamble. A second data field transmitted on a second resource unit allocated to the second station includes a midamble subfield. A first data field transmitted on a first resource unit allocated to the first station includes a useful information subfield. The useful information subfield includes useful data information, and the useful information subfield is located before a first OFDM symbol corresponding to the midamble subfield.
