A method is provided for receiving, at a receiving device, a control information message from a transmitting device. An example method includes determining at a user equipment (UE) a status of the UE and monitoring at the UE based on the status either a common search space (CSS) of a cell or a UE-specific search space (USS) of the cell. The cell is a cell of a secondary eNodeB for communicating with the UE. The method may further include monitoring a CSS and a USS of a cell of a master eNodeB (MeNB) simultaneously while monitoring either the CSS or the USS of the cell of the secondary eNodeB. The status may be a status of the UE with respect to a Random Access Channel (RACH) procedure with the cell.
