    • Embodiments herein relate to a method in a user equipment (10) for handling control information in a radio communications network. The user equipment (10) is served in a cell controlled by a radio network node (12) and is of a second type of user equipments. The user equipment 10 monitors a search space for control information of a physical data control channel, PDCCH, which search space is associated with the second type of user equipments. The PDCCH comprises at least one control channel element that comprises resource elements at least partly comprised in a second region of resource elements. The resource elements of the second region are only allowed to be scheduled for control information to user equipments of the second type. The at least one CCE is define in relation to a CCE of a first region of resource elements, which resource elements of the first region are allowed to be scheduled for control information to user equipments of a first type. The user equipment (10) detects control information within the monitored search space, and uses the detected control information for communicating with the radio network node (12).
    • 本文的实施例涉及用于在无线电通信网络中处理控制信息的用户设备(10)中的方法。 用户设备(10)在由无线电网络节点(12)控制的小区中服务,并且是第二类型的用户设备。 用户设备10监视用于物理数据控制信道的控制信息的搜索空间,该搜索空间与第二类型的用户设备相关联。 PDCCH包括至少一个控制信道元素,其包括至少部分地包括在资源元素的第二区域中的资源元素。 仅允许第二区域的资源元素被调度到第二类用户设备的控制信息。 所述至少一个CCE相对于资源元素的第一区域的CCE定义,所述第一区域的资源元素被允许被调度以用于第一类型的用户设备的控制信息。 用户设备(10)检测所监视的搜索空间内的控制信息,并使用检测到的控制信息与无线网络节点(12)进行通信。
