The method includes receiving DCI scheduling an uplink transmission; identifying a DCI format of the DCI; selecting, from a plurality of sets of preconfigured values, a set of preconfigured values that is mapped to the DCI format; and determining a number of times the uplink transmission is required to be repeated from the selected set of preconfigured values. A UE applying the same method is also provided. ## Claims ### Claim 1 A method performed by a User Equipment (UE) for repetition transmissions, the method comprising: receiving Downlink Control Information (DCI) scheduling an uplink transmission; identifying a DCI format of the DCI; selecting, from a plurality of sets of preconfigured values, a set of preconfigured values that is mapped to the DCI format; determining a number of times the uplink transmission is required to be repeated from the selected set of preconfigured values; receiving a Radio Resource Control (RRC) configuration indicating a number of sets of preconfigured values in the plurality of sets of preconfigured values; and determining whether to apply a non-slot-based repetition scheme to perform the uplink transmission according to the DCI format and the RRC configuration, wherein the non-slot-based repetition scheme allows the UE to perform the uplink transmission and at least one repetition of the uplink transmission in a same slot. ### Claim 2 (depends on 1) The method of claim 1, wherein determining the number of times the uplink transmission is required to be repeated comprises: selecting, from the selected set of preconfigured values, a preconfigured value indicated by the DCI; and determining the number of times the uplink transmission is required to be repeated according to the selected preconfigured value. ### Claim 3 (depends on 1) The method of claim 1, wherein each of the plurality of sets of preconfigured values is mapped to a respective DCI format. ### Claim 4 (depends on 1) The method of claim 1, wherein the RRC configuration comprises a Bandwidth Part (BWP)-specific configuration that is dedicated to a specific BWP. ### Claim 5 (depends on 1) The method of claim 1, wherein each of the plurality of sets of preconfigured values is included in a respective Time Domain Resource Allocation (TDRA) list. ### Claim 6 (depends on 1) The method of claim 1, wherein the uplink transmission comprises a Physical Uplink Shared Channel (PUSCH) transmission. ### Claim 7 A User Equipment (UE) that performs repetition transmissions, the UE comprising: one or more non-transitory computer-readable media storing one or more computer-executable instructions; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the one or more computer-executable instructions to perform operations comprising: receiving Downlink Control Information (DCI) scheduling an uplink transmission; identifying a DCI format of the DCI; selecting, from a plurality of sets of preconfigured values, a set of preconfigured values that is mapped to the DCI format; determining a number of times the uplink transmission is required to be repeated from the selected set of preconfigured values; receiving a Radio Resource Control (RRC) configuration indicating a number of sets of preconfigured values in the plurality of sets of preconfigured values; and determining whether to apply a non-slot-based repetition scheme to perform the uplink transmission according to the DCI format and the RRC configuration, wherein the non-slot-based repetition scheme allows the UE to perform the uplink transmission and at least one repetition of the uplink transmission in a same slot. ### Claim 8 (depends on 7) The UE of claim 7, wherein determining the number of times the uplink transmission is required to be repeated comprises: selecting, from the selected set of preconfigured values, a preconfigured value indicated by the DCI; and determining the number of times the uplink transmission is required to be repeated according to the selected preconfigured value. ### Claim 9 (depends on 7) The UE of claim 7, wherein each of the plurality of sets of preconfigured values is mapped to a respective DCI format. ### Claim 10 (depends on 7) The UE of claim 7, wherein the RRC configuration comprises a Bandwidth Part (BWP)-specific configuration that is dedicated to a specific BWP. ### Claim 11 (depends on 7) The UE of claim 7, wherein each of the plurality of sets of preconfigured values is included in a respective Time Domain Resource Allocation (TDRA) list. ### Claim 12 (depends on 7) The UE of claim 7, wherein the uplink transmission comprises a Physical Uplink Shared Channel (PUSCH) transmission.
