determining a set of nominal PUSCH repetitions according to the one of the plurality of items, a number of nominal PUSCH repetitions in the set of nominal PUSCH repetitions being indicated by a first parameter included in the one of the plurality of items; and

transmitting at least one actual PUSCH repetition that is determined based on the set of nominal PUSCH repetitions,

wherein each nominal PUSCH repetition in the set of nominal PUSCH repetitions maps to one of the plurality of TCI states.

2. The wireless communication method according to claim 1 , wherein the one of the plurality of items further includes a second parameter that indicates a mapping type between the set of nominal PUSCH repetitions and the plurality of TCI states.

3. The wireless communication method according to claim 2 , wherein the mapping type is a cyclic mapping type or a sequential mapping type.

4. The wireless communication method according to claim 1 , further comprising:

determining the at least one actual PUSCH repetition by splitting the set of nominal PUSCH repetitions across at least one slot boundary or across at least one symbol that is considered invalid for Uplink (UL) transmission,

wherein:

the at least one actual PUSCH repetition comprises a first actual PUSCH repetition and a second actual PUSCH repetition,

the first actual PUSCH repetition and the second actual PUSCH repetition are split from a same nominal PUSCH repetition in the set of nominal PUSCH repetitions, and

5. The wireless communication method according to claim 1 , wherein the third information corresponds to a Time Domain Resource Assignment (TDRA) list.

6. The wireless communication method according to claim 1 , wherein the UE is further configured with fourth information that indicates a time-domain offset between two neighboring nominal PUSCH repetitions in the set of nominal PUSCH repetitions.

7. The wireless communication method according to claim 6 , wherein the time-domain offset is configured by the BS per a nominal PUSCH repetition basis.

8. The wireless communication method according to claim 1 , wherein each two neighboring nominal PUSCH repetitions in the set of nominal PUSCH repetitions have a same time-domain offset.

9. A User Equipment (UE) for performing repetition-based Uplink (UL) transmissions, the UE comprising:

at least one processor; and

at least one memory coupled to the at least one processor, the at least one memory storing computer-executable instructions that, when executed by the at least one processor, cause the UE to:

receive a Radio Resource Control (RRC) message from a Base Station (BS), the RRC message comprising

first information indicating a repetition type that supports more than one repetition transmission within a slot,

second information indicating a plurality of Transmission Configuration Indicator (TCI) states configured for the UE, and

third information including a plurality of items, each of the plurality of items configuring a Physical Uplink Shared Channel (PUSCH) resource allocation;

receive Downlink Control Information (DCI) that indicates one of the plurality of items;

determine a set of nominal PUSCH repetitions according to the one of the plurality of items, a number of nominal PUSCH repetitions in the set of nominal PUSCH repetitions being indicated by a first parameter included in the one of the plurality of items; and

transmit at least one actual PUSCH repetition that is determined based on the set of nominal PUSCH repetitions,

wherein each nominal PUSCH repetition in the set of nominal PUSCH repetitions maps to one of the plurality of TCI states.

10. The UE according to claim 9 , wherein the one of the plurality of items further includes a second parameter that indicates a mapping type between the set of nominal PUSCH repetitions and the plurality of TCI states.

11. The UE according to claim 10 , wherein the mapping type is a cyclic mapping type or a sequential mapping type.

12. The UE according to claim 9 , wherein the computer-executable instructions further cause the UE to:
