    • Uplink control channel synchronization in heterogeneous network deployment There are provided measures for uplink control channel synchronization in a heterogeneous network deployment. Such measures may exemplarily comprise that a base station requests a switching of an uplink control channel at a terminal by means of a request including an indication of a cell out of serving cells for the terminal, the uplink control channel of which is requested to be switched to, and that the base station switches to the requested uplink control channel upon determination of completion of switching to the requested uplink control channel at the terminal. Further, such measures may exemplarily comprise that the terminal, upon receipt of the request, determines completion of switching to the requested uplink control channel at the base station, and that the terminal switches to the requested uplink control channel upon determination of completion of switching to the requested uplink control channel at the base station. When the request further comprises an assignment of a dedicated random access channel resource, the terminal may perform a random access procedure based thereon and then perform a transmission of the assigned dedicated random access channel resource on the indicated cell to the base station, whereupon both the terminal and the base station may determine the completion of switching to the requested uplink control channel at the other side, respectively.
    • 异构网络部署中的上行链路控制信道同步在异构网络部署中提供了上行链路控制信道同步的措施。 这样的措施可以示例性地包括基站通过请求包括终端的服务小区中的小区的指示的请求来请求终端上行链路控制信道的切换,上行链路控制信道被请求切换 并且当确定在终端处对所请求的上行链路控制信道的切换完成时,基站切换到所请求的上行链路控制信道。 此外,这样的措施可以示例性地包括终端在接收到请求时确定在基站处切换到所请求的上行链路控制信道的完成,并且终端在确定切换到的完成时切换到所请求的上行链路控制信道 在基站处请求的上行链路控制信道。 当请求还包括专用随机接入信道资源的分配时,终端可以基于其进行随机接入过程,然后在指示小区上向基站执行所分配的专用随机接入信道资源的传输, 终端和基站可以分别确定在另一侧切换到所请求的上行链路控制信道的完成。

    • 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).
