Abstract: A method and an apparatus for transmitting a physical layer protocol data unit that can provide a short training field sequence for a larger channel bandwidth. The short training field sequence has a smaller peak-to-average power ratio PAPR and better performance. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a short training field, a length of a frequency domain sequence of the short training field is greater than a first length, and the first length is a length of a frequency domain sequence of a short training field of a PPDU transmitted on a channel with a bandwidth of 160 MHz; and sending the PPDU on a target channel, where a bandwidth of the target channel is greater than 160 MHz.

Abstract: An AID allocation method for a multi-link device, includes: An access point multi-link device generates and sends a first frame. Correspondingly, a station device receives and parses the first frame to obtain an AID that is allocated to the station device and carried in the first frame. The AID is neither a BSSID that can be supported by a first-type access point in the access point multi-link device nor an identifier of an access point in the access point multi-link device. The first-type access point is an access point for establishing a link between the station device and the access point multi-link device.

Abstract: Example methods and apparatus for implementing collision detection in data transmission are described, One example method includes sending a data packet including collision detection information to a receive end, where the collision detection information is used by the receive end to perform collision detection on the data packet. A status indication message sent by the receive end is received by the receive end when sending the data packet. The receive end parses the status indication message. If the status indication message includes collision information, the receive end perform retransmission of the data packet.
