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: The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel includes a plurality of RUs, and the non-contiguous MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.
