Abstract: In an information transmission method, a sending device sends a data frame to a receiving device. The data frame occupies a transmission resource block, a bandwidth occupied by the transmission resource block is greater than 160 MHz, and the data frame comprises resource unit RU allocation information. The sending device determines indication information based on a resource block size indicated by the RU allocation information and a location of a 160 MHz channel within the bandwidth occupied by the transmission resource block, with the 160 MHz channel having more data tones in the transmission resource block. The sending device determines a response resource block based on the indication information and the RU allocation information, and then receives an acknowledgment frame for the data frame from the receiving device on the response resource block.

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: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.
