1. A method for scheduling on multiple cells, the method comprising:
receiving:
first information for a set of M cells,
second information for first search space sets for receptions of first physical downlink control channels (PDCCHs), and
a first PDCCH from the first PDCCHs, wherein:
the first PDCCH provides a first downlink control information (DCI) format, and
the first DCI format schedules transmissions of first physical uplink shared channels (PUSCHs) on respective first cells from the set of M cells;
determining that a transmission of a physical uplink control channel (PUCCH) with hybrid automatic repeat request acknowledgement (HARQ-ACK) information would overlap with transmissions of second PUSCHs, from the first PUSCHs, on respective second cells from the first cells; and
transmitting the first PUSCHs on the respective first cells, wherein the HARQ-ACK information is included only in a PUSCH, from the second PUSCHs, that is transmitted on a cell with a smallest index from the second cells.
