Abstract
The invention allows flexible disabling/enabling of cross-carrier scheduling in carrier-aggregated wireless data transmission. In response to detecting a predetermined disabling indication of cross-carrier scheduling of received carrier aggregated wireless data transmission, the disabling indication targeting subframes allocated to uplink in a first component carrier transmitted from a cross-carrier scheduling cell and to downlink in a second component carrier transmitted from a cross-carrier scheduled cell: a downlink control region in the targeted subframes in the second component carrier is monitored for uplink/downlink grants; and in response to detecting an uplink/downlink grant, the detected uplink/downlink grant is utilized in uplink/downlink scheduling of the targeted subframe in the second component carrier.
