实施例5：
网络侧通过一个DCI调度多个CC上的数据传输。在所述DCI中引入新的载波组合指示域，用于指示该DCI调度的N个CC的组合。具体方式与实施例1-4类似，在此不再赘述。

包含调度载波在内的CC组合；
或者，不包含调度载波在内的CC组合；
实施中对于具体的组合没有任何限制。具体的，假设高层信令配置的多个CC组合为{CC#0，CC#1}或者{CC#1},假设其中CC#0为调度载波，则表示该DCI同时调度CC#0和CC#1上的数据传输。当然实施中对于具体的CC数量不做任何限定。
进一步的，该高层配置为per search space配置或者per CORESET配置，即指示在特定search space或者CORESET内传输的一个DCI用于调度所述多个CC上的数据传输。
