Abstract: This application provides a data sending method and a communication apparatus. The method includes: A first node determines, based on a quality of a channel between the first node and a second node, a sending time for starting to send data, where the first node is one of several candidate previous-hop nodes of the second node. The first node starts to send the data to the second node at the sending time. According to the data sending method, when a node needs to send data to a next-hop node of the node, the node may determine, based on quality of a channel between the node and the next-hop node of the node, a sending time for starting to send the data.

Abstract: A method, apparatus, and system is disclosed. The method includes: A first terminal obtains a first update request. The first terminal sends a first message to a remote processing center, or the first terminal sends a second message to a local processing center, where both the first message and the second message carry information corresponding to the first update request. The first terminal obtains a fourth message sent by the local processing center, where the fourth message carries second update information obtained after the local processing center performs a preset processing operation on first update information, and the first update information is information obtained by the remote processing center in response to the first message or the third message. The first terminal updates output information of the first terminal based on the second update information carried in the fourth message.

Abstract: This disclosure provides an information transmission method and a communications device. The method includes: when determining that higher layer signaling is not configured with a scrambling identifier, scrambling or descrambling, by a communications device, data by using a second initial scrambling value, where the scrambling identifier is used by the communications device to determine a first initial scrambling value used for data scrambling or descrambling, and the second initial scrambling value is related to at least one or two of a cell identifier, a radio network temporary identifier, and a reserved bit. Therefore, in the embodiments of this disclosure, when determining that the higher layer is not configured with the scrambling identifier, the communications device scrambles or descrambles the data by using the second initial scrambling value. This resolves a problem in the prior art that a terminal device cannot determine an initial scrambling value used for data scrambling.
