    Abstract: This application discloses a multi-hop transmission method and an apparatus, which are applicable to fields such as V2X, internet of vehicles, intelligent connected vehicles, assisted driving, and intelligent driving, to resolve a problem that a multi-hop transmission latency is large in a conventional technology. In example embodiments, terminal devices participating in multi-hop transmission may share a shared resource pool. A first terminal device and a second terminal device participating in the multi-hop transmission are used as an example. The multi-hop transmission method includes: sending, by the first terminal device, data to the second terminal device on a first resource in the shared resource pool; and if the first terminal device fails to send the data on the first resource, retransmitting, by the first terminal device, the data to the second terminal device on a second resource in the shared resource pool.

    Abstract: An uplink control information transmission method includes: determining, by a terminal device, symbols occupied by first uplink control information in M time resource units; and transmitting the first uplink control information based on the symbols occupied by the first uplink control information in the M time resource units, where the first uplink control information occupies some or all symbols that are used to transmit uplink control information in each of the M time resource units, and occupies all symbols that are used to transmit the uplink control information in each of N−M time resource units other than the M time resource units.

    Abstract: This disclosure provides a data transmission method and a communication apparatus. The method includes: A first device receives first scheduling indication information and second scheduling indication information from a second device, where the first scheduling indication information indicates a first transmission resource from the second device to the first device, and the second scheduling indication information indicates a second transmission resource from the first device to a third device. The first device receives transmission data from the second device on the first transmission resource. When the transmission data is successfully received by the first device, the first device sends the transmission data to the third device on the second transmission resource.

    Abstract: This application discloses an uplink data sending method, an uplink data receiving method, and a communication apparatus. The sending method includes: A first terminal device sends first indication information to a network device, where the first indication information is used to determine a first precoding codebook subset to be used by a virtual terminal device. In this way, the network device sends configuration information to the first terminal device based on the first precoding codebook subset to be used by the virtual terminal device, so that the first terminal device sends data to the network device based on the first precoding codebook subset.
