receiving, by the terminal device, a Radio Resource Control (RRC) signaling sent by the network device, wherein the RRC signaling comprises the configuration information, and the configuration information comprises a corresponding relationship between a BWP and an SFI.

2. The method according to claim 1 , wherein the target SFI is an SFI corresponding to a currently activated BWP.

3. The method according to claim 1 , wherein the target SFI is used to indicate a slot structure within a slot.

4. The method according to claim 3 , wherein performing, by the terminal device, the data transmission according to the target SFI, comprises:

performing, by the terminal device, the data transmission within each slot according to a corresponding target SFI.

5. The method according to claim 1 , wherein the target SFI is used to indicate a slot structure of a corresponding slot of N slots, wherein N is a positive integer greater than 1.

6. The method according to claim 5 , wherein performing, by the terminal device, the data transmission according to the target SFI, comprises:

performing, by the terminal device, the data transmission within every N slots according to the slot structure corresponding to the each slot of the N slots.

7. A method for transmitting data, comprising:

determining, by a network device, one or more Slot Format Indicators (SFIs) corresponding to one or more Bandwidth Parts (BWPs) configured for a terminal device, wherein the SFI is used to indicate a slot structure within at least one slot; and

sending, by the network device, configuration information to the terminal device through a Radio Resource Control (RRC) signaling, wherein the configuration information is used to configure the one or more SFIs corresponding to the one or more BWPs; wherein the RRC signaling comprises the configuration information, and the configuration information comprises a corresponding relationship between a BWP and an SFI.

8. A terminal device, comprising: a memory, a processor, an input interface, and an output interface; wherein the processor is configured to execute instructions stored in the memory and cause the terminal device to:

receive, via the input interface, configuration information sent by a network device through a Radio Resource Control (RRC) signaling, wherein the configuration information is used to configure one or more Slot Format Indicators (SFIs) corresponding to one or more Bandwidth Parts (BWPs) configured for the terminal device; wherein the RRC signaling comprises the configuration information, and the configuration information comprises a corresponding relationship between a BWP and an SFI;

determine a currently used target SFI according to the configuration information; and

control the input interface or the output interface to perform data transmission according to the target SFI.

9. The terminal device according to claim 8 , wherein the target SFI is an SFI corresponding to a currently activated BWP.

10. The terminal device according to claim 8 , wherein the target SFI is used to indicate a slot structure within a slot.

11. The terminal device according to claim 10 , wherein the terminal device is further caused by the processor to:

perform the data transmission within each slot according to a corresponding target SFI.

12. The terminal device according to claim 8 , wherein the target SFI is used to indicate a slot structure of a corresponding slot of N slots, wherein N is a positive integer greater than 1.

13. The terminal device according to claim 12 , wherein the terminal device is further caused by the processor to:

perform the data transmission within every N slots according to the slot structure corresponding to the each slot of the N slots.

14. A network device, comprising: a memory storing instructions, a processor, an input interface, and an output interface; wherein the processor is configured to execute the instructions stored in the memory and cause the network device to:

determine one or more Slot Format Indicators (SFIs) corresponding to one or more Bandwidth Parts (BWPs) configured for a terminal device, wherein the SFI is used to indicate a slot structure within at least one slot; and

control the output interface to send configuration information to the terminal device through a Radio Resource Control (RRC) signaling, wherein the configuration information is used to configure the one or more SFIs corresponding to the one or more BWPs; wherein the RRC signaling comprises the configuration information, and the configuration information comprises a corresponding relationship between a BWP and an SFI.
