III. Step 3
1. For the last slot in the slot set, one or more M sub-slot duration PUSCH resources mapped to the corresponding last slot are merged into one and determined as a single PUSCH resource having a symbol duration of {M×D}.
IV. Step 4
1. For the middle slot in the slot set, a single PUSCH resource having the slot duration is allocated to each slot.
3) Opt 3
A. DCI Signaling for PUSCH Scheduling
i. The DCI may indicate 1) a first slot index K where PUSCH transmissions/resources are indicated, 2) an in-slot starting symbol index S and a symbol duration D of the first sub-slot duration PUSCH resource in the corresponding first slot, 3) the number of middle slots to which slot duration PUSCH resources are allocated N_m or the total number of slots to which PUSCH resources are allocated N_s (in this case, it is assumed that N_m=N_s?2), and 4) a (in-slot) last symbol index E of the PUSCH resource allocated to the last slot.
B. Determination of PUSCH Resources
I. Step 1
1. To configure a slot set, consecutive N_m slots are determined as middle slots starting from K+1, which is the slot index immediately following the first slot, and K+N_m+1, which is the slot index immediately following the last middle slot among the middle slots, is determined as the last slot.
2. One or more (L) sub-slot duration PUSCHs of the duration D are repeatedly mapped L times such that the PUSCHs are adjacent to each other, starting from the symbol index S in the first slot (to the in-slot last symbol only in the first slot).
