    • Format of a downlink control channel for a user equipment UE is changed in conjunction with switching the UE between being enabled for cross carrier scheduling and being disabled for cross carrier scheduling. The changed format is used on at least one serving cell of the UE's configured set of component carriers CCs. In one embodiment the changed format comprises an explicit carrier indicator field CIF for the case in which the switching is from disabled to enabled; and the changed format has no explicit CIF when the switching is from enabled to disabled. In another embodiment switching from disabled to enabled comprises the UE's configured set of CCs being changed from one to multiple cells; and switching from enabled to disabled comprises the UE's configured set of CCs being changed from multiple cells to one cell. In one embodiment the changed format is implicit.
    • 用户设备UE的下行链路控制信道的格式随着UE在交叉载波调度被使能并被禁用以进行交叉载波调度之间的切换而改变。 改变的格式用于UE配置的分量载波CC集合的至少一个服务小区。 在一个实施例中,改变的格式包括用于切换从禁用到启用的情况的显式载波指示符字段CIF; 并且当切换从使能到禁用时,更改的格式没有明确的CIF。 在另一个实施例中,从禁用到启用的切换包括UE被配置的一组CC从一个小区改变为多个小区; 并且从使能切换到禁用包括UE配置的一组CC从多个小区改变为一个小区。 在一个实施例中,改变的格式是隐含的。
