Beschreibung
Zusammenfassung:	A radio physical layer protocol data unit PPDU sending method includes: obtaining, by a sending apparatus, a radio PPDU, where the PPDU includes a HE-SIG-A and a HE-SIG-B, the HE-SIG-A includes a field used to indicate a quantity of OFDM symbols in the HE-SIG-B, and when different MCSs are used, or whether DCM is used, or different bandwidths are used for HE-SIG-B field transmission, a same value in the field used to indicate the quantity of OFDM symbols in the HE-SIG-B indicates different quantities of OFDM symbols; and sending the PPDU, so that a receiving apparatus determines, with reference to the different MCSs, or whether the DCM is used, or the different bandwidths and based on a value of the field used to indicate the quantity of OFDM symbols in the HE-SIG-B, the quantity of OFDM symbols in the HE-SIG-B.
