Abstract: An access point receives restricted target wake time setup request information sent by a station. The restricted target wake time setup request information is used to request to set up a restricted target wake time. The access point sends restricted target wake time response information to the station. The restricted target wake time response information is used to respond to the restricted target wake time setup request information. The restricted target wake time setup request information or the restricted target wake time response information includes indication information of a first access category corresponding to low-latency traffic of the station. The station or the access point can independently and selectively configure the access category for the low-latency traffic.

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: A method includes: generating, by an access point AP, a first frame, where the first frame includes P station information fields, each of the P station information fields corresponds to one resource unit RU allocated to a first station STA, P is a positive integer greater than 1, each station information field further includes end indication information, and the end indication information is used to indicate whether the station information field is the last station information field in the P station information fields. The AP may allocate P RUs to the first STA, and indicate the P RUs to the first STA through the P station information fields in the first frame. Therefore, a resource allocation manner of the AP can be more flexible, a frequency selective gain of an OFDMA system can be effectively improved, and a system capacity can be increased.

Abstract: This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.
