1. A method for processing downlink control information (DCI) formats, the method comprising:
receiving a first physical downlink control channel (PDCCH) on a first cell that provides a first DCI format; and
determining a set of fields in the first DCI format, wherein:
the first DCI format schedules a first physical downlink shared channel (PDSCH) reception, or a first physical uplink shared channel (PUSCH) transmission, only on the first cell,
the set of fields includes a carrier indicator field (CIF) when a second DCI format provided by a second PDCCH reception on a second cell can schedule a second PDSCH reception, or a second PUSCH transmission, on the first cell, and
the set of fields does not include the CIF when the second DCI format provided by the second PDCCH reception on the second cell cannot schedule the second PDSCH reception, or the second PUSCH transmission, on the first cell.
