Abstract: Methods, apparatus, and systems for joint transmission are provided. In one aspect, a joint transmission method includes: sending, by a first AP, a first PPDU to a first STA and a second STA, and sending, by a second AP, a second PPDU to the first STA. A sending time of sending the first PPDU is same as a sending time of sending the second PPDU. The first PPDU includes a first preamble field and a first data field, and the second PPDU includes a second preamble field and a second data field. The first preamble field is same as the second preamble field. The first data field carries first data information sent to the first STA and second data information sent to the second STA, and the second data field carries the first data information.

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: A coordinated transmission control method, apparatus, and system are disclosed. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test, further determine an anti-interference beamforming manner based on a specific cell configuration parameter, and determine whether to perform coordinated transmission with reference to the dual decision condition of the interference test, so that the access points can learn an interference status in advance, thereby preventing unnecessary retransmission resulting from interference caused during actual coordinated transmission, and improving communication efficiency.

Abstract: A first station generates indication information of any one of an operating channel, an operating band, or an operating channel and an operating band of a wake-up receiver in a second station. The first station sends the indication information, so that the wake-up receiver in the second station works on the indicated operating channel or the indicated operating band. The first station controls the operating channel or the operating band of the wake-up receiver in the second station by generating the indication information.
