    • There is provided a timing entity (108) for a communication network (100} which includes a base station (102) and a user equipment (104) capable of communicating with each other over at least two carriers which have different temporal configuration of its uplink and downlink resources. The timing entity (108) comprises a control entity (10) adapted for determining timing data (120) defining a timing of a control signalling transmission (112) which is related to a data transmission (114) on a first carrier and which uses a resource of a first type on the second carrier. According to an embodiment the timing data (120) specify for the control signalling transmission (112) a time slot in which there is available a resource of the first type on the second carrier (132) for the control signalling transmission (112). The control entity (108) may be implemented in a base station (102} and/or a user equipment (104).
    • 提供了一种用于通信网络(100)的定时实体(108),其包括基站(102)和能够通过至少两个载波进行通信的用户设备(104),所述载波具有其上行链路的不同时间配置 定时实体(108)包括适于确定定时数据(120)的控制实体(10),定时数据(120)定义与第一载波上的数据传输(114)有关的控制信令传输(112)的定时 根据一个实施例,定时数据(120)为控制信令传输(112)指定在第二载波上可用第一类型的资源的时隙 控制实体(108)可以在基站(102)和/或用户设备(104)中实现。
