1. A trigger frame transmission method, comprising:
sending, by an access point (AP), a trigger frame for triggering a station to send an extremely high throughput trigger based physical layer protocol data unit (EHT TB PPDU), wherein the trigger frame comprises a universal signal field (U-SIG) reserved indication field indicating a value of a U-SIG reserved field in the EHT TB PPDU; and
receiving, by the AP, the EHT TB PPDU sent by the station in response to the trigger frame, wherein the value of the U-SIG reserved field in a U-SIG of the EHT TB PPDU is determined based on a value of the U-SIG reserved indication field in the trigger frame,
wherein a common information field of the trigger frame comprises four uplink spatial reuse parameter (UL SRP) field.
