Abstract: Example methods for indicating downlink service data and devices are described. One example method includes controlling, by a first station (STA) associated with a radio access point (AP), a wake-up receiver of the first STA to wake up within a preset first listen interval. The first STA receives a wake-up beacon frame sent by the AP, and controls main radio (MR) of the first STA not to wake up within a second listen interval to receive a beacon frame sent by the AP. According to the method provided in this application, the MR of the first STA does not need to wake up within the second listen interval to receive the beacon frame broadcast by the AP.

Abstract: This application provides a wake-up method and device. The method includes: receiving, by a wake-up radio, a first wake-up frame, where the first wake-up frame includes a duration field, and the duration field is used to carry duration information; and waking up, by the wake-up radio, a primary radio based on the duration information. Because a wake-up frame transmitted by an access point includes duration information, a wake-up radio of a station wakes up a primary radio based on the duration information, so that the station can save energy better.

Abstract: A communication method in a wireless local area network and a communication apparatus are provided. The method includes an access point generating a trigger frame, and sending the trigger frame to a station. The trigger frame includes resource allocation information and first indication information. The first indication information indicates a first bandwidth to the station, and the resource allocation information indicates a first distributed resource unit (RU) that is allocated to the station and that corresponds to the first bandwidth. The first bandwidth is a bandwidth of at least one sub-channel occupied by subcarriers included in the first distributed RU. According to the method, the station may determine a distributed bandwidth range of an allocated RU, for example, in a maximum bandwidth supported by the station, or in a bandwidth outside a punctured bandwidth, to increase a transmit power of the station.

Abstract: The present disclosure relates to the field of WLAN technologies, and discloses a target wake time-based communication method, an apparatus, and a system, which may be applied to a wireless communication system that supports the 802.11be standard. According to the method, an AP indicates a candidate traffic identifier corresponding to allowed to be transmitted within a restricted TWT SP. When requesting to join a restricted TWT, a STA selects one or more traffic identifiers from the candidate traffic identifier indicated by the AP. Traffic corresponding to the traffic identifier selected by the STA requested by the STA to transmit within the restricted TWT SP. After receiving a request of the STA for joining the restricted TWT, the AP may allow the STA to join the restricted TWT, to transmit, within the restricted TWT SP, the traffic corresponding to the traffic identifier selected by the STA.
