B. Two data mapping types to be respectively applied to the middle slot and the last slot are indicated by a single DCI.
2) Method 2
A. For the last-slot PUSCH, one fixed data mapping type (e.g., B) is applied.
B. Two data mapping types to be respectively applied to the first slot and the middle slot are indicated by a single DCI.
3) Method 3
A. For the middle-slot PUSCH, one fixed data mapping type (e.g., A or B) is applied.
B. Two data mapping types to be respectively applied to the first slot and the last slot are indicated by a single DCI.
4) Method 4
A. Three data mapping types to be respectively applied to the first, middle, and last slots are indicated by a single DCI.
In the case of conventional DCI scheduling a single PUSCH transmission in one slot (such DCI is referred to as “single-slot DCI” for convenience), SRS transmission at a specific time may be indicated by an aperiodic SRS (a-SRS) request field in the corresponding DCI. Specifically, one SRS resource set (or multiple SRS resource set in carrier aggregation (CA)) and a (DCI-to-SRS) slot offset (K_s) indicating the SRS transmission time may be configured (independently) for each state signaled by the corresponding a-SRS request field/bit. Here, one SRS resource set may include one or a plurality of SRS resources (consecutive or nonconsecutive in the time domain), and one SRS resource may include one or a plurality of SRS symbols (consecutive in the time domain).
