Flexible disabling/enabling of cross-carrier scheduling in carrier-aggregated wireless data transmission

摘要

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.

1. A method, comprising:
detecting a 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, wherein the detecting includes examining received time division duplex uplink/downlink configurations and cross-carrier scheduling configurations to determine if one or more of the targeted subframes exist; monitoring a downlink control region in the targeted subframes in the second component carrier for uplink/downlink grants; and utilizing the detected uplink/downlink grant in uplink/downlink scheduling of the targeted subframe in the second component carrier in response to detecting an uplink/downlink grant.
