Abstract
Embodiments herein relate to a method in a user equipment for handling control information in a radio communications network. The user equipment is served in a cell controlled by a radio network node and is of a second type of user equipments. The user equipment 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 defined 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 detects control information within the monitored search space, and uses the detected control information for communicating with the radio network node.
