<p>A method implemented in a user equipment (UE) use in a wireless communications network configured to support carrier aggregation. The method comprises receiving, from a base station, downlink control information (DCI) in a physical downlink control channel (PDCCH) on a component carrier (CC), wherein the DCI is configured to have either a first DCI format with a non-zero-bit carrier indicator field (CIF) or a second DCI format with a zero-bit CIF.</p> |
