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).

Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.
