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: Embodiments of this application provide an access point (AP) multi-link device discovery method and a related apparatus, for example, in a wireless local area network (WLAN) supporting IEEE 802.11be. In an example method, a reporting AP sends a first management frame to a station. The first management frame carries information about a reported AP. The reporting AP is affiliated with an AP multi-link device. The reported AP is affiliated with the same multi-link device as the reporting AP. Or the reported AP belongs to a same multiple basic service set identifier (BSSID) set as another AP in the multi-link device with which the reporting AP is affiliated.

Abstract: Embodiments provide a multi-link communication method and a related apparatus. A first station generates a radio frame, where the first station is one of a plurality of stations included in a first multi-link device. The first multi-link device includes a first station operating on a first link and a second station operating on a second link. The first station transmits the radio frame on the first link, where the radio frame includes capability indication information, and the capability indication information indicates whether the first station and the second station support simultaneous transmitting/receiving operations. According to the embodiments of this application, communication quality can be ensured.

Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

Abstract: Embodiments of this application disclose a method for determining a data buffer status, and an apparatus. The method includes: A first MLD receives first indication information from a second MLD, and determines, based on the first indication information and a correspondence between an association identifier of the first MLD and a data type supported by the first MLD, a buffer status of bufferable data that corresponds to the at least one data type and that is in the second MLD, where the first indication information is used to indicate the buffer status of the bufferable data. According to the embodiments of this application, a data buffer status in a data type dimension can be determined. The embodiments of this application may be applied to a wireless local area network system that supports a next-generation Wi-Fi EHT protocol of the IEEE 802.11, that is, the 802.11 protocol such as 802.11be.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.

Abstract: Embodiments of this application relate to the communication field, and in particular, to a multi-link communication method and an apparatus. A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.
