Abstract: This application provides a method for transmitting a wake-up packet in a communications system and a device. The communications system includes a transmit end device and a receive end device. The receive end device includes a wake-up receiver and a main transceiver. The method includes: sending, by the transmit end device, a first wake-up packet WUP to the wake-up receiver by using a first data rate; determining, by the transmit end device, a second data rate; and sending, by the transmit end device, a second WUP to the wake-up receiver by using the second data rate. The transmit end device can determine a proper data rate for sending a wake-up packet based on a specific transmission condition in a communication process, thereby improving transmission efficiency of the wake-up packet.

Abstract: A method for coordinated communication and an apparatus for coordinated communication are provided. The method includes: a first access point (AP) sends an announcement message and/or a polling message to one or more second APs. The announcement message announces that the first AP may share a time resource of the first AP. The announcement message may further include identifier information that indicates the one or more second APs, and time information that indicate communication or channel contention of the one or more second APs in the time resource shared by the first AP. The polling message may be used to notify a second AP to start to use, at a preset time, a channel resource shared by the first AP with the second AP for communication or start channel contention at the preset time.

Abstract: This application provides information sending and receiving methods and apparatuses. This application provides a new PPDU format. In some instances, a long training sequence in the new PPDU format is orthogonal to a legacy long training sequence or orthogonal to a high throughput long training sequence. By using this long training sequence, a format of a PPDU can be automatically detected, so as to further process the PPDU according to a network standard corresponding to the format of the PPDU. In addition, when a target long training field is read, the format of the PPDU can be detected, thereby, in at least some implementations, saving time for detecting the format of the PPDU, improving efficiency of detecting the format of the PPDU, and completing a task of detecting the format of the PPDU as early as possible.

Abstract: A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.
