10.11 Multi-cell scheduling by a single DCI

Multi-cell scheduling by a single DCI allows the PDCCH of a serving cell to schedule PDSCH(s)/PUSCH(s) on one or more serving cells with the single DCI but with the following restrictions:

• When a serving cell is configured with a PDCCH which schedules PDSCH(s)/PUSCH(s) on a cell set, the PUSCH/PDSCH on serving cells in the cell set is always scheduled by a PDCCH on the serving cell;
• When SpCell is configured with a PDCCH which schedules PDSCH(s)/PUSCH(s) on serving cells in a cell set, that SpCell's PDSCH and PUSCH cannot be scheduled by a PDCCH on an SCell;
• When an SCell is configured with a PDCCH which schedules PDSCH(s)/PUSCH(s) on serving cells in a cell set, SpCell is not included in the cell set;
• The scheduling PDCCH and the scheduled PDSCH(s)/PUSCH(s) can use the same or different numerologies;
• The co-scheduled PDSCH(s) with a PDCCH can use the same or different numerologies;
• The co-scheduled PUSCH(s) with a PDCCH can use the same or different numerologies.
