    Abstract: Embodiments of this application disclose a communication method, a related device, and a system. The method includes: receiving, by a network device, a first preamble sequence that is sent by a first terminal in a time window; sending, by the network device, a response message to the first terminal based on the first preamble sequence; receiving, by the network device, a first message sent by the first terminal, where the first message includes information used to identify the first terminal; and sending, by the network device, a second message to a second terminal and the first terminal, where the second message is used to indicate that the first terminal and the second terminal belong to a same user equipment cooperative group. According to this application, efficiency of establishing a user equipment cooperative group can be improved.

    Abstract: The present invention provides a WLAN system resource indication method and apparatus. The method includes: generating, by an access point, a frame that carries resource indication information; and sending, to multiple stations, the frame that carries the resource indication information. The resource indication information includes multiple pieces of sub resource indication information. Correspondingly, each piece of the sub resource indication information uniquely corresponds to one of the multiple stations. Therefore, a station side does not need read the entire resource indication information, so as to reduce resource overheads and improve efficiency.

    Abstract: One embodiment of the invention describes a synchronization signal sending method applied to an unlicensed frequency band. To ensure transmission fairness, a network device performs listen before talk (LBT) before a start time for transmitting a synchronization signal, to determine whether a channel is busy or idle. When the channel is busy, the network device cannot transmit the synchronization signal at the expected start time for transmitting the synchronization signal. Therefore, the network device performs LBT again within a preset time length after the start time, and sends the synchronization signal when determining that the channel is idle by performing LBT again. When the channel is idle, the network device preempts a channel resource, and sends the synchronization signal the expected start time for transmitting the synchronization signal.
