Claim of US Patent No. 10,893,472

1. An access point (AP) for data transmission in a wireless local area network, the AP comprising:a processor, configured to: generate first indication information when a station (STA) has a data transmission requirement and the AP accepts the data transmission requirement, wherein the first indication information comprises information for indicating a first target wakeup moment, and the first target wakeup moment is not later than a sending moment of a target trigger frame that the STA needs to listen to next time, and is not earlier than a sending moment of a first beacon frame in a beacon frame period in which the target trigger frame is sent, wherein information about the first target wakeup moment is one of the following content: the sending moment of the first beacon frame in the beacon frame period in which the target trigger frame is sent; a sending moment of the first trigger frame comprised in a trigger frame subgroup to which the target trigger frame belongs; the sending moment of the target trigger frame; and the first target wakeup moment; and when determining not to accept the data transmission requirement of the STA, generate second indication information for indicating that the AP does not accept the data transmission requirement of the STA; and
a transceiver, configured to send the first indication information to the STA.
