    • 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。

    • The disclosure relates to use of carriers for aggregation in a wireless system. A set of carriers available for use in carrier aggregation is first determined. It is then determined if at least one carrier of the set of carriers can become unavailable for use by a communication device. An indication of a configuration type of the at least one carrier is sent to the communication device, the configuration type being indicative of different behavior during a period. The at least one carrier is maintained in the set of carriers during said period. The communication device receives the indication. If a change in the availability state of the at least one carrier is determined, the communication is operated, device in relation to the at least one carrier, according to the availability state and the received indication during said period.
    • 本公开涉及在无线系统中使用载波进行聚合。 首先确定可用于载波聚合的一组载波。 然后确定该组载波中的至少一个载波是否变得不可供通信设备使用。 将至少一个载波的配置类型的指示发送到通信设备,该配置类型在一段时间内指示不同的行为。 在所述期间,至少一个载体被保持在该组载体中。 通信装置接收指示。 如果确定所述至少一个载波的可用性状态的改变,则在所述时段期间根据可用性状态和接收到的指示来操作与所述至少一个载波相关的设备的通信。
