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 is applied to a wireless local area network supporting 802.11, to an NDPA frame transmission method and apparatus. The method includes: A beamformer (for example, an AP) generates and sends a universal NDPA frame, where an NDPA variant field (namely, B0 and B1 in a sounding dialog token field) included in the universal NDPA frame is set to any one of 00, 01, 10, and 11, and every two octets following the sounding dialog token field in the universal NDPA frame include one AID 11 or one disambiguation bit. If the AID 11 is in a station information field, the AID 11 is less than or equal to 2007; or if the AID 11 is in an extended common field, the AID 11 is greater than 2007. The disambiguation bit is forcibly set to 1. Embodiments of this application prevent an STA of an earlier version from misreading.

Abstract: This application provides a spatial reuse method and apparatus based on multi-access point (AP) coordination, and a system. In the method, a first access point AP sends a radio frame including identification information to a second access point AP. The identification information is used to indicate the second access point AP to perform spatial reuse during uplink data transmission performed by at least one first station associated with the first access point. The second access point sends a downlink frame to at least one second station based on the identification information. Through coordination between access points APs, the first AP may configure a spatial reuse transmission opportunity for another specific AP to perform spatial reuse transmission, so that a transmission time in the spatial reuse transmission opportunity is fully used, thereby avoiding a conflict and improving transmission efficiency.

Abstract: This application relates to the field of wireless fidelity Wi-Fi technologies, and in particular, to a non-simultaneous transmitting and receiving capability indication method, an apparatus, and a system. In the method, a first multi-link device MLD may sequentially transmit an association request frame and a management frame to a second MLD. Correspondingly, the second MLD may receive the association request frame and the management frame from the first MLD. The association request frame includes first information, and the first information indicates a first NSTR capability between a first link and a second link. The management frame includes second information, and the second information indicates a second NSTR capability between the first link and the second link.

Abstract: A data transmission method includes sending, by a first station in a first multi-link device, a third frame. The third frame indicates the first station enables a mode of sharing a quantity of spatial streams. The mode of sharing the quantity of spatial streams is used for enabling the first station to use the shared spatial streams. A quantity of shared spatial streams is a maximum quantity of shared spatial streams supported by the first multi-link device. The data transmission method also includes receiving, by the first station, a fourth frame. The fourth frame is used for responding to the third frame.

Abstract: This application provides data transmission methods and apparatuses, to introduce a buffer status report (BSR) mechanism through multi-link (ML) cooperation, to improve performance of scheduling a station by an ML device. In an example method, a multi-link transmit end determines BSR signaling sent to a multi-link receive end, where the BSR signaling can enable the multi-link receive end to schedule a station of the multi-link transmit end over one or more links. Further, the multi-link transmit end sends the B SR signaling to the multi-link transmit end over the one or more links. This introduces a BSR mechanism through ML cooperation.

Abstract: A power save method and a communication apparatus that are applied to multi-link communication. A multi-link device sends a mode switching frame to another device to notify the other device that the multi-link device is to switch a communication mode, for example, switch from a multi-link conventional communication mode to a multi-link power save communication mode, or switch from the multi-link power save communication mode to the multi-link conventional communication mode. The multi-link conventional communication mode includes a first configuration. The multi-link power save communication mode includes the first configuration and a second configuration. A quantity of links used for transmission under the first configuration is greater than a quantity of links used for transmission under the second configuration. A balance is provided between a high rate and low power consumption.
