Abstract: This application discloses a data transmission method that includes: scrambling to-be-transmitted data, to obtain scrambled data; and sending the scrambled data to a receive device. The initialization bits of a scrambler used to scramble the data include a first bit sequence and a second bit sequence. The first bit sequence is carried in a service field of the to-be-transmitted data, the second bit sequence reuses a bit in a signal field of a physical layer protocol data unit (PPDU), and the quantity of the initialization bits is equal to the order of the scrambler. In embodiments of this application, when the transmit device and the receive device use the scrambler with a higher order than that in the conventional technology, the initialization bits of the scrambler are based on bits in an existing service field used for data scrambling and reused bits in some signal fields.

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: This application provides a channel sounding method and apparatus. The method includes: A first communication device sends a first frame to a second communication device, where the first frame is used to indicate the second communication device to perform channel sounding on a part of antennas of the first communication device. The first communication device sends a second frame to the second communication device, where the second frame is used by the second communication device to perform channel sounding on the part of antennas. The first communication device receives a third frame from the second communication device, where the third frame is used to indicate a result of performing channel sounding on the part of antennas.

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.
