Abstract: This application provides an information transmission method and a communication apparatus. The method includes: A first device sends TWT resource configuration information in a first BSS to a second device. The first device is located in the first BSS, the second device is located in a second BSS, and the first BSS and the second BSS at least partially overlap. According to the information transmission method provided in this application, TWT resource configuration information in a plurality of BSSs is shared among the plurality of BSSs in an OBSS scenario. Therefore, collision can be further avoided during data transmission in different BSSs in the OBSS scenario, thereby improving quality and assurance of data transmission between devices in the plurality of BSSs, and improving efficiency of data transmission in the OBSS scenario.

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: A method for transmitting an extremely high throughput long training field (EHT-LTF) sequence includes: A first communication device generates and sends an extremely high throughput physical layer protocol data unit (EHT PPDU), where the EHT PPDU includes an EHT-LTF; and correspondingly, a second communication device receives the EHT PPDU, and parses the EHT-LTF in the received EHT PPDU. In this way, an LTF sequence can be designed for the IEEE 802.11be standard, and a PAPR value of the LTF sequence on a resource unit can be reduced.

Abstract: A first station in a first multi-link device generates a frame, wherein the frame indicates a maximum quantity of shared spatial streams supported by the first multi-link device. The first station sends the frame. A throughput of a station in a multi-link device is improved by enabling a station to use more spatial streams.

The method includes: A reporting AP sends a management frame to a station. The reporting AP belongs to a first AP MLD, and belongs to a multiple BSSID set. The management frame includes MLD information. The MLD information carries, by using different types of MLD elements and a multiple BSSID element, for example, information about another AP in the MLD to which the AP belongs, information about the multiple BSSID set to which the AP belongs, and information about an AP in a multiple BSSID set including the another AP in the MLD to which the AP belongs. The station obtains information about the reporting AP and other information about a reported AP based on the management frame.
