    Abstract: Embodiments of the present disclosure disclose a data communication method and apparatus. The data communication method includes: when receiving a PPDU, obtaining, by a network node, a BSS identifier in the PPDU; if the BSS identifier in the PPDU is different from a first BSS identifier, and the BSS identifier in the PPDU is the same as a second BSS identifier, determining whether the PPDU meets a preset spatial reuse condition, where the first BSS identifier is an identifier of a first BSS to which the network node belongs, the second BSS identifier is an identifier of an extended BSS to which a target relay belongs, and the target relay and the network node belong to the first BSS; and if the PPDU meets the preset spatial reuse condition, contending for an access channel, and communicating with a station other than the target relay in the first BSS.

    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 a method including: generating, by an access point (AP), a plurality of first media access control MAC frames, where the plurality of first MAC frames are corresponding to a plurality of stations (STAs) in a one-to-one manner, and each of the plurality of first MAC frames carries a target wake time (TWT) parameter of a corresponding STA or instruction information for instructing a corresponding STA to send a TWT parameter to the AP; and sending, by the AP, a corresponding first MAC frame to each of the plurality of STAs simultaneously, where the first MAC frame is used to determine a TWT parameter with a STA corresponding to the first MAC frame. According to embodiments of this application, the AP can simultaneously negotiate with the plurality of STAs a TWT parameter of each STA by sending the corresponding first MAC frame to each of the plurality of STAs simultaneously.
