Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.

Abstract: Methods and apparatuses of parallel data transmission are disclosed. In one embodiment, a first node generates a physical protocol data unit (PPDU) that carries indication information. The indication information is used to indicate whether a second node is allowed to perform parallel data transmission by spanning a time length of the PPDU and indicate a boundary crossing time length of the parallel data transmission. The first node is included in a first basic set service (BSS), and the second node is included in a second BSS. The first node sends the PPDU.

Abstract: A data communication method and system are provided. In the method, a station sends sequence numbers to at least two APs, where the sequence numbers indicate a sequence in which the APs respond to the station. The station broadcasts a wake-up message to the at least two APs. The station receives acknowledgement messages sequentially returned by the at least two APs according to the sequence numbers of the APs. The station determines according to the sequentially returned acknowledgement messages, whether the corresponding APs need to transmit the downlink data. The station sequentially completes, according to the sequence numbers, downlink data transmission with the APs.

Abstract: A data transmission method and apparatus, and relates to the communication field. In the method, after obtaining a path parameter of each of at least one communication path between a first device and a second device, the first device may demodulate first data based on a pilot and the path parameter of each communication path. In other words, when demodulating the first data, the first device may refer to not only the pilot but also the path parameter of each communication path. The path parameter of each communication path can assist in demodulating the first data. When the path parameter of each communication path assists in demodulating the first data, there may be no need for too many pilots. Therefore, a resource occupied by the pilot can be reduced.
