Abstract:
A method in the field of networking technologies for sending a wake up packet, an apparatus, and a device. The method for sending a wake up packet is applied to a first node, wherein the first node maintains a first contention window (CW1) on a first channel, the first channel is a channel on which a main transceiver of a second node works, and the method includes generating a backoff count based on CW1, executing backoff based on the backoff count, and sending a wake up packet to the second node on a second channel when backoff ends, wherein the second channel is a channel on which a wake up receiver of the second node works.
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.
