1. A communication method, comprising:
generating, by an access point (AP), a trigger frame, wherein:
the trigger frame comprises an uplink length field, a common information field and a user information field,
the uplink length field is used to indicate lengths indicated by legacy signal (L-SIG) fields in a high efficient trigger based physical layer protocol data unit (HE TB PPDU) and an extremely high throughput physical layer protocol data unit (EHT PPDU), or the uplink length field is used to indicate a length indicated by an L-SIG field in an EHT PPDU, and
an uplink bandwidth field in the common information field and the user information field in the trigger frame jointly indicate an uplink bandwidth used for sending the EHT PPDU;
sending, by the AP, the trigger frame; and
determining, by the AP, a received PPDU is an EHT PPDU according to a length indicated in an L-SIG field in the received PPDU is a multiple of three.
