1. A data transmission method, comprising:
configuring, by a network device, a plurality of different frequency domain resources, and configuring, by the network device, a same time domain resource for the plurality of different frequency domain resources; and
sending, by the network device, a same downlink control signaling on a plurality of beams, using the same time domain resource with the plurality of different frequency domain resources;
wherein the plurality of different frequency domain resources belong to a same control resource set (CORESET) or a plurality of CORESETs having different frequency domain resources,
wherein the plurality of different frequency domain resources in the CORESET or the plurality of CORESETs comprise one or more same configuration parameters, and
the configuration parameters comprise one or more of: a number of time domain symbols, a cycle of a search space, a slot offset of the search space, or a starting symbol position monitored in a slot of the search space;
wherein, the plurality of different frequency domain resources comprise frequency domain resources corresponding to the plurality of CORESETs with different second CORESET pool indexes and different frequency domain resources;
wherein the method further comprises:
indicating, by the network device, TCI states of the plurality of beams based on a plurality of second radio resource control (RRC) signalings and one or more second MAC signalings;
wherein, the plurality of second RRC signalings are configured to respectively indicate TCI state lists of the plurality of CORESETs with different second CORESET pool indexes; and
the one or more second MAC signalings are configured to activate TCI states, wherein a number of activated TCI states is less than or equal to a number of the plurality of different frequency domain resources.
