1. A data transmission method, comprising:
determining, by a terminal device, L sounding reference signal (SRS) resources, wherein L is an integer greater than 1, and at least two SRS resources of the L SRS resources correspond to different spatial relations;
determining, by the terminal device based on a first correspondence between an SRS resource and a physical uplink shared channel (PUSCH) transmission, an SRS resource used for each of Q PUSCH transmissions; and
performing, by the terminal device, the Q PUSCH transmissions using the L SRS resources, wherein Q is an integer greater than 1;
wherein the first correspondence between the SRS resource and the PUSCH transmission comprises:
sequentially mapping resources to all transmissions based on a configuration order of the resources, and if there is still a remaining quantity of transmissions to which no resource is mapped, sequentially and cyclically mapping the resources to the remaining quantity of transmissions based on the configuration order of the resources;
sequentially mapping resources to all transmission groups based on the configuration order of the resources using P continuous transmissions as one transmission group, and if there is still a remaining transmission group to which no resource is mapped, sequentially and cyclically mapping the resources to the remaining transmission group based on the configuration order of the resources, wherein P is an integer greater than 1; or
sequentially mapping resources to all transmission groups based on the configuration order of the resources using the P continuous transmissions as the one transmission group, and if there is still the remaining quantity of transmissions to which no resource is mapped, sequentially and cyclically mapping the resources to the remaining quantity of transmissions based on the configuration order of the resources.
