Data transmission method, terminal device and network device

A network device, comprising a processor, a transceiver, and a memory, the processor, the transceiver, and the memory communicate with each other through an internal connection path, when the processor executes instructions stored by the memory, the network device is caused to:

• send first resource indication information to a terminal device at a first moment, the first moment being located in an n-th time domain resource unit, the first resource indication information indicating a frequency domain resource allocated for transmission of a target channel in an (n+i)-th time domain resource unit, and the target channel comprising a data channel or a control channel of the terminal device, where n and i are positive integers;
• wherein the network device is further caused to send second resource indication information to the terminal device at a second moment after the first moment, the second resource indication information indicating a time domain resource allocated for transmission of the target channel in the (n+i)-th time domain resource unit;
• wherein the time domain resource allocated for transmission of the target channel in the (n+i)-th time domain resource unit is determined by the network device after the first moment, and wherein the frequency domain resource allocated for transmission of the target channel in the (n+i)-th time domain resource unit is determined by the network device before the second moment.
