Systems and methodologies are described that facilitates identifying control information for two or more carriers in a multi-carrier system or environment. User equipment (UE) identifications (IDs) can be assigned for a user equipment, wherein each user equipment (UE) identification (ID) can correspond to a specific carrier. Upon receipt of control information related to a plurality of carriers from an anchor carrier, the user equipment (UE) identifications (IDs) can be utilized in order to identify which control information corresponds to each carrier. The user equipment (UE) identification (ID) can be, for example, a Cell Random Network Temporary Identity (C-RNTI).
