Abstract: A method for sending a physical layer protocol data unit (PPDU) may be applied to some scenarios in which PPDU alignment is implemented. For example, in multi-link transmission of non-simultaneous transmit and receive, it is ensured that a time error of simultaneous ending of a plurality of PPDUs does not exceed 8 microseconds. In the method, a transmitter controls duration of one or more fields of a packet extension (PE) field, an Extremely High Throughput (EHT)-signal (SIG) field, and an EHT-long training field (LTF) field of the PPDU, and/or delays a sending time of the PPDU so that an error between an end time of the PPDU and a specific time (for example, a first time) is not greater than an error threshold, thereby implementing PPDU alignment.

Abstract: This application provides a communication method, an access network device, a terminal device, and a core network device. In a process in which the terminal device is handed over from a first access network device to a second access network device, the second access network device learns of first service progress of the first access network device based on a first sequence number of a data packet forwarded by the first access network device, without introducing additional progress exchange information between the two access network devices.

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.

Abstract: A non-AP MLD or a first STA in the non-AP MLD generates a first frame. The first frame includes indication information for indicating padding duration for a channel switch delay in an initial control frame. The padding duration is determined based on duration of a control response frame. The non-AP MLD or the first STA or another STA in the non-AP MLD transmits the first frame. An AP MLD or a first AP or another AP in the AP MLD receives the first frame. The AP MLD or the first AP determines the padding duration of the initial control frame based on the indication information.

The announcement frame includes a duration field, a value of the duration field is set to a first duration, an end time of the first duration is not later than an end time of a target trigger frame or is not later than a start time of a target trigger based (TB) physical layer protocol data unit (PPDU), the target trigger frame is a next radio frame of the announcement frame, the target TB PPDU is a response frame for the target trigger frame, the target trigger frame comprises a second trigger frame, and the target TB PPDU comprises a second TB PPDU. The slave access point sends the second trigger frame to a second station associated with the slave access point, and receives the second TB PPDU from the second station.
