1. A radio physical layer protocol data unit (PPDU) sending method, comprising:
obtaining, by a first apparatus, a radio PPDU, wherein the PPDU includes a high efficiency-signal field A (HE-SIG-A) and a high efficiency-signal field B (HE-SIG-B); and the HE-SIG-A includes a field that indicates a quantity of OFDM symbols in the HE-SIG-B, wherein
when a value of the field is a specific value, the value indicates that the quantity of OFDM symbols included in the HE-SIG-B is greater than or equal to 16; and when a value of the field is another value, the value indicates the quantity of OFDM symbols included in the HE-SIG-B; and
sending the PPDU.
