A user equipment terminal (UE) operates in a wireless network according to a configuration. The UE receives the configuration for a physical downlink control channel (PDCCH), and detects downlink control information (DCI) in the PDCCH. From the DCI, the UE receives control information for a serving cell configured with one or more bandwidth units in a frequency domain. The control information is provided for each bandwidth unit of the serving cell. According to the control information, the UE performs a downlink reception from the serving cell or an uplink transmission to the serving cell.
