Abstract: A data communication method and apparatus are provided. The data communication method includes: receiving, by a station (STA), a wake-up packet sent by an access point (AP), where the wake-up packet includes basic service set (BSS) parameter indication information, the BSS parameter indication information includes BSS parameter change indication information or a target parameter of a primary BSS to which a primary transceiver of the STA currently belongs, and the BSS parameter change indication information is used to indicate whether a critical parameter of the primary BSS changes when the primary transceiver of the STA is in a sleep state; and communicating, by the primary transceiver of the STA, with the AP based on the BSS parameter indication information. The embodiments of the present application can be used to effectively ensure that the primary transceiver of the STA successfully communicates with the AP.

Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).

Abstract: This application is applicable to a group addressed traffic transmission method applicable to a plurality of links and an apparatus. In the method, group addressed traffic indication information is used to indicate whether each AP or an AP other than a first AP in an AP MLD has group addressed traffic; or group addressed traffic indication information is used to indicate whether each AP or an AP other than a first AP in an AP MLD and each AP or an AP other than a non-transmitted AP in an AP MLD in which the non-transmitted AP in a multiple BSSID set in which the first AP is located have group addressed traffic. This application is applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, an 802.11 series protocol such as 802.11be.
