Patent ID: 11792785

Abstract:
Methods and apparatuses for enhancing scheduling flexibility for operation with carrier aggregation. A method for processing downlink control information (DCI) formats includes 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. The first DCI format schedules a first physical downlink shared channel (PDSCH) reception, or 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 PUSCH transmission, on the first cell. The set of fields does not include the CIF when the second DCI format cannot schedule the second PDSCH reception, or PUSCH transmission, on the first cell.
