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.

Abstract: Embodiments of this application provide a radio channel data processing method, a communication apparatus, and a related device. In the method, a first communication device may send an uplink resource request message to a second communication device. The uplink resource request message includes source distribution information and a first modulation and coding scheme determined based on the source distribution information. The first communication device receives an uplink resource allocation message from the second communication device. The uplink resource allocation message includes a modulation and coding scheme allocated by the second communication device to the first communication device. The first communication device performs modulation and coding on an information bit based on the second modulation and coding scheme. This helps improve coding performance of the first communication device.
