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: 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: This application provides a communication method and apparatus, and relates to the field of communication technologies. An AP generates a trigger frame, where the trigger frame includes a first user information field, a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field before the first user information field is located on a primary 160 MHz channel, and a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field after the first user information field is located on a secondary 160 MHz channel. Then, the AP sends the trigger frame.

Abstract: An access point receives restricted target wake time setup request information sent by a station. The restricted target wake time setup request information is used to request to set up a restricted target wake time. The access point sends restricted target wake time response information to the station. The restricted target wake time response information is used to respond to the restricted target wake time setup request information. The restricted target wake time setup request information or the restricted target wake time response information includes indication information of a first access category corresponding to low-latency traffic of the station. The station or the access point can independently and selectively configure the access category for the low-latency traffic.

Abstract: This application provides methods and apparatus for sending feedback information. By binding a BAR-BA feedback manner, that is, first a request and then a feedback, when it is determined that data retransmission is performed by using a hybrid automatic repeat request (HARQ) mechanism, duration of an acknowledgment operation performed by a data receive end on retransmitted data may be increased. Alternatively, the receive end estimates duration required for feeding back a receiving status of the retransmitted data, and feeds back the duration to a transmit end. The transmit end may therefore adaptively adjust duration of the retransmitted data based on a feedback capability of the receive end, to ensure that the feedback of the receive end on the receiving status of the retransmitted data is within a short inter-frame space (SIFS).
