Abstract

Apparatuses and methods for multi-slot/physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH) scheduling on multiple cells. A method for a user equipment (UE) includes receiving first information for a number of sets of cells, receiving a physical downlink shared channel (PDCCH) that provides a downlink control information (DCI) format, receiving first more than one PDSCH on first more than one cell, determining hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits, and transmitting a physical uplink control channel (PUCCH) or a PUSCH that provides the HARQ-ACK information bits. The DCI format schedules receptions of the first more than one PDSCH on the first more than one cell in a set s of cells from the number of sets of cells. The first more than one PDSCH include one or more PDSCHs on each cell from the first more than one cell.
