1. A method for receiving downlink control information (DCI), comprising:
determining a first set of candidate number of a first set of aggregation level (AL) for receiving a first DCI; and
receiving the first DCI according to the first set of candidate number and the first set of AL on a first cell,
wherein the first DCI is configured for scheduling physical downlink shared channels (PDSCHs) on a plurality of cells, the plurality of cells comprises a second cell and a third cell, and the first set of candidate number and the first set of AL are corresponding to a search space with a first identity,
wherein the method further comprises:
receiving the PDSCHs on the second cell and the third cell according to the first DCI, wherein the PDSCHs comprises a first PDSCH on the second cell and a second PDSCH on the third cell, the first PDSCH is received on a second slot, and the second slot is the nth slot and the latest slot among at least one slot configured for receiving the PDSCHs respectively on the plurality of cells;
transmitting a HARQ-ACK feedback on a first slot for the first PDSCH and the second PDSCH, wherein the first slot is the (n+K1)th slot, and the value K1 is a fixed value indicated by a DCI field of the first DCI for the first PDSCH and the second PDSCH,
wherein the second cell and the third cell are different cells, and the value K1 is an integer greater than 0,
wherein the (n+K1)th slot for transmitting the HARQ-ACK feedback of the first PDSCH and the second PDSCH respectively on the second cell and the third cell is determined according to the value K1 indicated by the DCI field and the latest slot among the at least one slot configured for receiving the PDSCHs.
