Abstract: The technology of this application is directed to reducing a data transmission latency in multi-hop transmission and improving data transmission efficiency, A method is provided and may be applied to a multi-hop transmission system. The method includes a first node obtaining second transmission parameter information. The second transmission parameter information may include one or more of the following: quality of service (QoS) configuration information, candidate transmission path information, candidate transmission resource information, or a candidate forwarding mode. The first node determines first transmission parameter information based on the second transmission parameter information. The first node sends service data to a second node based on the first transmission parameter information, where the second node is a next-hop node determined by the first node based on the first transmission parameter information.

Abstract: Examples communication methods and communications apparatus are described. In one example method, a base station sends a first synchronization signal block, where the first synchronization signal (SS) block includes a primary SS, a secondary SS, and information carried on a physical broadcast channel (PBCH). In addition, the base station sends a second SS block, where the second SS block includes a primary SS or includes a primary SS and a secondary SS, and does not include information carried on the PBCH. The first SS block is used by a terminal to access the base station. The second SS block is used to perform time and frequency synchronization after the terminal accesses the base station.

Abstract: Embodiments of this application provide a retransmission method and a device. After receiving feedback information transmitted by a receiving device based on first information indicated by a retransmission mode, a transmitting device uses second information indicated by the retransmission mode to generate data retransmitted this time, and transmits the data to the receiving device based on third information indicated by the retransmission mode. In this process, a plurality of retransmission modes are set, so that when different retransmission modes are used, the first information used for transmitting the feedback information, the second information used for generating the retransmitted data, or the third information used for transmitting the retransmitted data is different. Therefore, objectives of reducing HARQ overheads and ensuring transmission efficiency, reliability, and latency performance of a wireless communications system are achieved.
