detecting DCI to indicate a usage situation of the at least one TO.

10. The method of claim 1 , wherein the repeatedly transmitting the uplink data on the at least one TO further comprises at least one of:

not counting a TO in which a time domain symbol conflicts with the transmission direction of the slot configuration into a number of repeated transmissions of the uplink data, and continuing the repeated transmissions of the uplink data on a TO configured later;

repeatedly transmitting uplink data corresponding to a TO in which a time domain symbol conflicts with the transmission direction of the slot configuration on a preconfigured redundant TO; or

repeatedly transmitting the uplink data on a preconfigured TO which does not conflict with the transmission direction of the slot configuration.

11. The method of claim 1 , wherein the slot configuration comprises at least the D symbol, at least one uplink (U) symbol, and at least the N consecutive F symbols.

12. A device for repeated transmission, comprising at least one processor configured to implement the method of claim 11 .

13. A method for receiving repeated transmission, comprising:

determining a plurality of transmission occasions (TOs) for uplink data to be repeatedly transmitted; and

in response to at least one TO, among the plurality of TOs for the uplink data to be repeatedly transmitted, being not conflicted with a transmission direction of a slot configuration, receiving repeatedly transmitted uplink data on the at least one TO,

wherein if the transmission direction of the slot configuration indicates N consecutive flexible (F) symbols, and an adjacent symbol before the N consecutive F symbols is a downlink (D) symbol, the uplink data is repeatedly transmitted from a time domain symbol corresponding to an M-th F symbol among the N consecutive F symbols, wherein M<N, and first (M−1) F symbols among the N consecutive F symbols serve as a guard period, wherein N is a first number and M is a second number.

14. The method of claim 13 , wherein each of the F symbols comprises a symbol that is flexibly configured in transmission direction.

15. The method of claim 13 , wherein N is 1, 2 or 8.

16. The method of claim 13 , wherein the slot configuration comprises at least the D symbol, at least one uplink (U) symbol, and at least the N consecutive F symbols.

17. A device for repeated transmission, comprising at least one processor configured to implement the method of claim 1 .

18. A device for receiving repeated transmission, comprising at least one processor configured to implement the method of claim 13 .

19. A non-transitory computer readable storage medium storing instructions, which when executed by one or more processors can cause the one or more processors to:

determine a plurality of transmission occasions (TOs), for uplink data to be repeatedly transmitted; and

in response to at least one TO, among the plurality of TOs for the uplink data to be repeatedly transmitted, being not conflicted with a transmission direction of a slot configuration, repeatedly transmit the uplink data on the at least one TO,

wherein if the transmission direction of the slot configuration indicates N consecutive flexible (F) symbols, and an adjacent symbol before the N consecutive F symbols is a downlink (D) symbol, the uplink data is repeatedly transmitted from a time domain symbol corresponding to an M-th F symbol among the N consecutive F symbols, wherein M≤N, and first (M−1) F symbols among the N consecutive F symbols serve as a guard period, wherein N is a first number and M is a second number.

determine a plurality of transmission occasions (TOs) for uplink data to be repeatedly transmitted; and

in response to at least one TO, among the plurality of TOs for the uplink data to be repeatedly transmitted, being not conflicted with a transmission direction of a slot configuration, receiving repeatedly transmit uplink data on the at least one TO,

wherein if the transmission direction of the slot configuration indicates N consecutive flexible (F) symbols, and an adjacent symbol before the N consecutive F symbols is a downlink (D) symbol, the uplink data is repeatedly transmitted from a time domain symbol corresponding to an M-th F symbol among the N consecutive F symbols, wherein M<N, and first (M−1) F symbols among the N consecutive F symbols serve as a guard period, wherein N is a first number and M is a second number.
