Abstract
This application provides a data transmission method, terminal device, and network device. The method includes: sending, by a terminal device, at least one precoded reference signal on at least one reference signal resource corresponding to a first PRG, where different precoding matrixes are used for different reference signals, and the first PRG is a PRG used to transmit a reference signal; receiving, by the terminal device, resource indication information, where the resource indication information indicates a reference signal resource that is corresponding to a second PRG and that is in the at least one reference signal resource, and the second PRG is a PRG used to transmit a physical uplink shared channel (PUSCH); and sending, by the terminal device, a precoded PUSCH on the second PRG based on the resource indication information, where a precoding matrix used for the PUSCH is a precoding matrix used for a reference signal sent on the reference signal resource corresponding to the second PRG. In this way, a precoding matrix used to transmit the PUSCH on the second PRG can be effectively selected.
